ital representations of designs. The enquiry goes on
to illustrate the implications that the making of a CAD
file available online might have. It suggests that the
act of uploading a CAD file onto a 3D printing plat-
form may be tantamount to a disclosure for the pur-
poses of triggering unregistered design protection,
and for appraising the state of the prior art. It also ar-
gues that, when measuring the individual character
requirement, the notion of “informed user” and “the
designer’s degree of freedom” may need to be recon-
sidered in the future. The following part touches on
the exceptions to design protection, with a special fo-
cus on the repairs clause set forth in Article 110 CDR.
The concluding part explores different measures that
may be implemented to prohibit the unauthorised

protected products.
Abstract: Three-dimensional printing (“3DP”)
is an additive manufacturing technology that starts
with a virtual 3D model of the object to be printed, the
so-called Computer-Aided-Design (“CAD”) file. This
file, when sent to the printer, gives instructions to the
device on how to build the object layer-by-layer. This
paper explores whether design protection is available
under the current European regulatory framework
for designs that are computer-created by means of
CAD software, and, if so, under what circumstances.
The key point is whether the appearance of a product,
embedded in a CAD file, could be regarded as a pro-
tectable element under existing legislation. To this
end, it begins with an inquiry into the concepts of “de-
sign” and “product”, set forth in Article 3 of the Com-
munity Design Regulation No. 6/2002 (“CDR”). Then,
it considers the EUIPO’s practice of accepting 3D dig-
A. What is three-dimensional
printing and what is a CAD file?
1
The term “three-dimensional printing” (“3DP”)
can be considered as an umbrella term that stands
for a set of related technologies building physical
objects by the consecutive addition of liquids,
sheet or powdered materials in ultra-thin layers.
Hence, in contrast with traditional “subtractive
manufacturing” technologies, which mostly rely
on the removal of material (e.g. cutting, drilling
and milling), 3DP is an “additive manufacturing”
technology. The peculiarity about 3DP is that every
physical object is created directly from a digital
le, the so-called Computer-Aided Design (CAD)
le. The latter is a virtual 3D model that serves to
send information to the printer on how to build the
object.
2 A CAD le can be obtained in different ways. First,
it can be created from scratch, by using modelling
software (“CAD software”). A number of open-source
software tools are freely available online. They enable
individuals with no prior experience in 3D modelling
to create their own designs, with some programs
providing pre-rendered shapes1. Furthermore, many
websites offer tutorials on modelling best practices
to assist users who are not design professionals2.
3
Second, an existing object could be turned quickly
into a virtual 3D model by using a 3D scanner. The
latter is a device that collects a huge amount of
data from a real-world object, by means of lasers
1 E.g. FreeCAD, Sketchup or ThinkerCad.
2 For example, Sculpteo provides a tutorial for users of the
Sketchup” 3D modelling software, available at:

printing-ketchup/.>

or x-rays. Hence, it reproduces a high-resolution
and accurate digital model of the scanned object
(“3D visualization”). Third, photogrammetry is a
valid alternative to 3D scanning. It is a photography
technique that uses software tools for stitching a
series of 2D photographs – taken from different
angles – together into a 3D model.
4 A CAD le can be saved in different formats, such as
the .stl format (“STereoLithography”) or the .amf
format (“Additive Manufacturing Format”). The .stl
format merely describes the surface geometry of a
three-dimensional object as a set of triangular faces,
whereas the .amf format is an XML-based format
inclusive of information about the volumetric
structure of the interior, composition, colour,
geometry and material.
5
At a second stage, CAD les need to be processed,
in order to become printable. Hence, a (CAD or
scanned) 3D model has to be segmented into a
number of layers by specialized software, so-called
“Computer-Aided Manufacturing” software or
“slicer”. The latter generates a G-code for each layer,
which contains commands to tell the printer how to
manufacture the object3. The slicing programs are
usually included with the printer or available online
for download4.
6
It emerges from the above considerations that three
consecutive steps have to be followed in an ordinary
3DP process: the creation of a virtual 3D model; the
deconstruction of the 3D model into a series of
slices (“slicing”), which are sent to the 3D printer
through a computer code; the nal print, consisting
in a layer-by-layer deposition of suitable materials.
7
3DP has gained a wider distribution among the
general public in recent years. The launch of Open
Source Hardware initiatives, such as the “Replicating
Rapid Prototyping” (“RepRap”) project5, together
with the expiration of a number of key patents on 3D
printing technologies, have contributed to a steady
improvement in the quality of personal 3D printers
and to a considerable reduction in hardware costs6.
The technology has, therefore, crossed over into
3 The CAD and CAM functions could also be integrated into a
single CAD/CAM program.
4 E.g. Slic3r, Cura and Skeinforge.
5 This project was launched by a research team at the
University of Bath. The idea was to create an open source
3D printer capable of reproducing its own spare parts. The
specications of the hardware (e.g. CAD les, mechanical
drawings, diagrams, etc.) were made freely available online
for anyone to use, modify and update. The RepRap project
could be realised because key patents, covering the fused
deposition modelling technique, had expired.

was offered for around €15.000. Today, the price for a
personal 3D printer ranges from €500 to € 2000.
the consumer sphere, with over 100,000 desktop 3D
printers having been sold so far7.
8
Furthermore, online platforms dedicated to the
dissemination of CAD les (“digital-design-le-
sharing”) have grown in popularity. These platforms
have contributed to the creation of a communication
infrastructure that is a powerful tool for co-creation.
They enable individuals to connect to a vast and
distributed network, where they can upload,
download, edit, remix, share or indeed sell a CAD
le, from which a 3D printed product will emerge.
9
Some recent studies, conducted by Rayna et
al.8, Moilanen et al.9, and Mendis et al.10, provide
examples of the diversity of existing 3DP platforms.
The latter include platforms, such as Thingiverse,
where users license their CAD les – rather than
selling them – under Creative Commons licences
(CC) or General Public Licence (GPL). By using CC
licences, the CAD le’s proprietor can withhold
certain rights (e.g. the right of attribution and the
right to make derivative works), and impose that
derivatives should be licensed under the same terms
as the licence of the original CAD le (the “Share
Alike” clause). Furthermore, the “Non Commercial
Use” clause restricts the possibility for the licensee
to use the CAD le for commercial purposes.
10
Other platforms, such as Cuboyo, offer paid
downloads to users’ CAD les (i.e. the 30% of the sale
price goes to the website, whereas the remaining
70% goes to the seller)
11
. Moreover, online platforms,
such as Shapeways and Sculpteo, offer printing and
delivery services on demand. Taking as an example
the architecture of Sculpteo, the 3DP process takes
place in the following way: individual users upload
their CAD les onto Sculpteo website; Sculpteo
automatically repairs any defect and optimizes the
digital blueprint, with its own 3D tools; then, it prints
the object and delivers it to costumers in nished
form, charging a price for its activities.

the near future is not altogether clear yet. For the
time being, 3D printing by individual makers reveals
major technical limitations to seriously hinder the
market for quality products. The 3DP community
is still a small niche, and the dissemination of CAD
les on the Internet is not a mass phenomenon yet.
So far, digital-design-le-sharing shows a high level
of participation by 3DP enthusiasts12. Furthermore,
to date, there is only evidence of IP infringement
occurring on a small scale, on online platforms such
as Thingiverse13.
12
Having noted that, the speed of technical
developments in consumer 3D printing is undeniable.
The level of precision and accuracy attainable by a
desktop 3D printer is steadily rising. The price of
printing material has dropped drastically, and the
technology has also become faster, more reliable
and cheaper.
13
Furthermore, there are continuous attempts to make
3D printing more easily accessible and affordable for
the average consumer. To give a recent example,
an Italian company specialized in rapid prototyping
and digital fabrication, called Solido 3D, came up with
one of the latest innovation in 3DP. It developed a
device, named “OLO”, which enables printing 3D
objects directly from a smartphone14. Because of its
size, weight, and battery power source, this device is
considered as the rst portable 3D printer, available
for sale at the price of $ 9915.
14
It is therefore maintained that, although personal
3D printers are still far from being ubiquitous, it
is just a matter of time until ordinary people will
manufacture – directly from a digital le – an
increasing number of items at the comfort of their
home. Furthermore, in the event that products are
not capable of being printed by means of personal
3D printer, it is possible to outsource the actual
manufacture to bureau services, such as Sculpteo
and Shapeways. Users can create online shopfronts,
where they display their own CAD les for products.
The Internet operator will then 3D print the product
on demand and deliver it worldwide.
12 Based on data extracted from 17 online platforms, the total
number of downloads, for the time-period 2008-2014, is
around 40.000. See Mendis, Secchi, UK Intellectual Property
Ofce (2015), supra note 7, p. 28.

blog (September 18, 2015). Retrieved February 7, 2016 from

15 OLO is a crowd-funded project, launched on kickstarter on
March 21, 2016. The aim of the developers of this portable
3D printer was to raise $ 80.000 in one month, whereas they
reached this goal in just thirty-three minutes. At the end of
the fundraising campaign, they collected $ 2,321,811 with
16,180 backers from all over the world.
I. Is a CAD file a computer program?
15
An emerging body of literature has addressed the
question of whether CAD les warrant copyright
protection16. Some scholars have suggested that
the denition of computer programs is perfectly
compatible with CAD les17. The present writer,
however, rejects former existing assumptions on
the application of this analogy.
16
As noted above, a CAD le simultaneously
encompasses both a “design drawing component”
and a “code component”. The latter serves to give
a series of instructions to the printer (i.e. where to
move the print head and how fast to deposit the
material). Even if a CAD le embeds a code, it is not
the equivalent of a computer program. This in light
of the fact that the designer of a CAD model does not
write the code herself, at least not directly.
17
As noted by Dolinsky, “the CAD designer ... “creates”
the code necessary to print the object only by
creating the design”, whereas the CAD software
programmer has already predetermined the code
associated with a pre-made shape or a free-hand
drawing18. It is therefore only the CAD software
that nds protection under the Software Directive
2009/24/EC, not the CAD le itself.
18
Although an enquiry on the copyright status of
CAD les goes beyond the purposes of the present
analysis, it is here suggested that a CAD le merely
serves as the medium in which a copyright protected
work (i.e. artistic work) is recorded. To the extent
that the design drawing component of the CAD le
is the expression of the author’s creativity, and is not
dictated by purely functional considerations, it may
qualify as a copyright protected work. By contrast,
the le itself is just the medium in which the work is
recorded. The fact that the work exists in digital le
format does not change its nature. In this respect,
a CAD le bears a certain similarity to other les,

such as JPG or PDF les, which respectively embed
a photograph or a literary work.
19
Therefore, the distinction between what is the
work of authorship, as opposed to the medium of its
expression, takes on a particular signicance when
claiming copyright protection of CAD les.
II. Aim of the present analysis
20
This paper explores whether design protection is
available under the current European regulatory
framework for designs that are computer-created
by means of CAD software, and, if so, under what
circumstances. The key point is whether the
appearance of a product, embedded in a CAD
le, could be regarded as a protectable element
under existing legislation. To this end, it begins
with an inquiry into the concepts of “design” and
“product”, set forth in Article 3 of the Community
Design Regulation No. 6/2002 (“CDR”). Then, it
considers the EUIPO’s practice of accepting 3D digital
representations of designs. The enquiry goes on to
illustrate the implications that the making of a CAD
le available online might have. It suggests that the
act of uploading a CAD le onto a 3D printing platform
may be tantamount to a disclosure for the purposes
of triggering unregistered design protection, and for
appraising the state of the prior art. It also argues
that, when measuring the individual character
requirement, the notion of “informed user” and
“the designer’s degree of freedom” may need to
be reconsidered in the future. The following part
touches on the exceptions to design protection,
with a special focus on the repairs clause set forth
in Article 110 CDR. The concluding part explores
different measures that may be implemented to
prohibit the unauthorised creation and sharing of
CAD les embedding design-protected products.
B. Designs in the European Union
21
For the purposes of the Community Design
Regulation (“CDR”), “design” means “the appearance
of the whole or a part of a product”19. While there
is no denition of appearance, Article 3(a) CDR
provides a non-exhaustive list of elements that one
may have to consider, for appraising the external
aspect of a product. These elements include the lines,
contours, colours, shape, texture and/or materials of
the product itself and/or its ornamentation. These
features are all perceivable by the human eye or by
the sense of touch, whereas sounds and smells are
19 Article 3(a) CDR.
not contemplated20. Yet the CDR does not make the
eye appeal a necessary prerequisite for registration.
22
Furthermore, as noted by the European Commission
in the 1991 “Green Paper on the Legal Protection of
Industrial Design”
21
, the external aspect of a product
is of considerable economic importance. The notion
of appearance, therefore, should be broad enough
to encompass any economic value attached to the
aspect of a product.
23 Article 3(b) CDR goes on to dene a product as “any
industrial or handicraft item other than computer
programs”. It then offers some guidance as to the
type of designs that are eligible for protection. The
latter include both three-dimensional designs, such
as packaging and get-up, and two-dimensional
designs, such as graphic symbols and typefaces
22
.
Designs of parts of products, for which no assembly
is required, and designs of component parts, which
are intended to be assembled in a larger complex
product, can also be protected23.
24 The concept of product, therefore, is central to the
whole structure of the CDR. The essence of a design
is the appearance of a product. Furthermore, as
explained below in more detail, there should be a
product, to which the design is applied, in order to
commit an infringement.
25
The following enquiry aims at analysing whether the
appearance of a product that is represented digitally
as a CAD le may attract design protection under
existing EU legislation.
I. The visual element of a CAD file
26
The ultimate generation of designs created by
means of CAD software embed all information that is
needed to dene the outer appearance of a product.
Embedded data can describe the geometry, as well
as the colours and materials of the product. In this
respect, the design-drawing component of a CAD
le differs from traditional blueprints or technical
drawings. In most cases, blueprints only dene the
geometrical aspect of an object. They may be seen as
graphical abstractions of the intended product that
need to be interpreted by a human being.
27
CAD les, instead, may dene all the properties

of America, 2nd edn., Sweet and Maxwell (2010), p. 95.

of Industrial Design, June 1991, at 2.1.2.

intended to be exhaustive.

and attributes of the product to be printed. They
may contain the entire product design that, when
printed, will be a nished 3D product. In such a case,
in parallel with a photograph, the visual element of a
CAD le – i.e. the image of the product stored therein
– may be regarded as a view of the appearance of
the nished product, for which protection is sought.
28
The CAD le can be seen as the medium in which the
design is rst recorded. Hence, as noted below, the
appearance of the product embodied therein may
enjoy Community design protection, irrespective of
whether the product comes into existence or not.
29
By contrast, in case where a CAD model does not
clearly reveal the outer appearance of the product, it
may be allegedly considered as a blueprint protected
in class 19-08 of the Locarno classication (i.e. “other
printed matters”)24.
II. Digital item embedded in a
CAD file: design protection?
30 The issue at stake is whether a digital item, which
is computer created by means of CAD software and
recorded in a CAD le, may attract design protection
in its own right, as a graphic symbol.
31
At rst reading, the notion of a “design” seems to be
conned to the appearance of products having some
physical form, insofar as the CDR makes express
reference to “industrial or handicraft items”, and
expressly excludes computer programs.
32 Hence, the denition of “product” set forth in the
CDR may give rise to a certain degree of uncertainty
as to whether a design, that is not applied to a
product in the sense of a physical, tangible object,
should likewise be considered as a protectable
element under existing regulation. The inclusion
of graphic symbols in the meaning of products
indicates that protectable designs need not be
tied to a physical dimension. The European Union
Intellectual Property Ofce (“EUIPO”) guidelines
provide some assistance in this respect. The Ofce’s
practice allows registration of screen displays, icons,
and other visible elements of a computer program,
such as graphical user interfaces (“GUIs”), in Locarno
class 14, Subclass 04 (“screen displays and icons”)25.
24 See EUIPO Guidelines for Examination of Registered
Community Designs, version of 01/08/2016, at 4.1.1.
25 Id., EUIPO Guidelines, at 4.1.3. Also, the Explanatory
Memorandum claries that the exclusion provided in the
CDR for computer programs does not extend to “specic
graphic designs as applied, for example, to icons or menus”.
See EU Commission, Explanatory Memorandum on the
Proposal for a European Parliament and Council Regulation
on the Community Design, 3 December 1993, p. 11.
33
Therefore, design protection appears to cover all
digital items – with the sole exclusion of sounds and
animated images – that appear on electronic devices,
such as computer screens or mobile phones.
34
By contrast, computer programs as such are excluded
from design protection. The reason for inserting
this exclusion is explained in the Explanatory
Memorandum of the rst proposal of the CDR.
The rationale was mainly to avoid any potential
interference with the Software Directive which
might arise whenever copyright protection provided
under the aforementioned Directive is supplemented
or reinforced by a protection of the “look and feel” of
a computer program by way of design protection26.
35
In theory, if a computer item is eligible for
protection, the digital item represented in a CAD le
could likewise enjoy Community design protection.
One may argue that, in parallel with other computer
icons, the item embodied in a CAD le is a graphic
symbol that appears on a computer screen when
the le is loaded. Since the CDR enumerates graphic
symbols as a category of product of their own, their
appearance can be protected under the title of
Community designs.
36 This analogy appears questionable, however. There
is a substantial difference between a computer icon
and a product embedded in a CAD le. The former
fulls its function exclusively once it is displayed on
a computer screen. As noted by Margoni, it does not
even possess the characteristics to be manufactured
or printed into an industrial or handicraft item27. It
is “intangible” by its very nature. On the contrary,
not only can an item embedded in a CAD le become
tangible once it is shown on a computer screen, but
it could also be turned into a physical product at the
click of a button.
37
In other terms, the reason why a person creates a
CAD le is to enable the manufacturing of the object
embodied therein. Design rights are vested in the
appearance of the product to be made from that le.
38
Having noted that, an applicant may also wish to
protect the virtual product per se under the scope
of European design law in order to avoid the risk
that no protection will be available, should a third
party make a digital copy of its design, i.e. creates
a CAD le depicting the design-protected product
and uploads such CAD le on the Internet. In fact,
as discussed below in more detail, Article 19 CDR
seems to conne infringing use of a design to use in
relation to physical goods or corporeal movables28.

39
For the sake of clarity, it seems rather unrealistic
to assume, in the absence of a specic provision,
that digital items represented in the form of CAD
les could be seen as “products”, whose appearance
deserves protection in its own right. The denition
of “design” would need to be broadened in future
legislation in order to cover a wider range of
“immaterial” protectable elements.
III. CAD drawings as graphical
representations
40 Under current practice, the drawing component of
a CAD le may serve as a “graphic representation”
of the design for which protection is sought. The
following analysis attempts to clarify this point.
41
A person seeking protection for their design at
the EU level has the option to either apply for a
Registered Community Design (“RCD”) through the
EUIPO, before disclosing it, or, alternatively, opt
for an anti-copying right, relying on Unregistered
Community Design (“UCD”) protection.
42
In the former case, in order to have a valid
application for a RCD, Article 36 CDR requires to
include “a representation of the design that is
suitable for reproduction”. There are several ways
in which a design can be represented. The EUIPO
accepts drawings, photographs and computer-made
representations (i.e. CAD representations), either in
black or in colour, provided that they are of quality,
permitting all details of the design to be clearly
distinguished29.
43
Hence, it may well be that, in parallel with a
photograph, a CAD representation is used to disclose
the features of the design for which protection is
sought. By way of explanation, if the applicant
wishes to register the design of a table knife, rather
than afxing a photograph of such a knife, she can
afx the 3D representation, created by CAD software,
of the same household good. The applicant will then
have to indicate “knives” as the relevant product
category (class 7-03 of the Locarno classication)30.
44
However, in order to be of quality, a CAD
representation should enable to determine, with
clarity, the subject matter of the protection afforded
by the RCD to its holder. Hence, it should contain
clear and intelligible information about the sizes,
dimensions, and colours of the item in which the
29 EUIPO Guidelines, supra note 25, at 3.3.1.
30 The EUIPO has recently released an e-ling tool, called “3D
image uploader”, that allows the applicant to upload and
store its CAD les. The applicant can move the 3D image,
zoom in and out, take some pictures from different views,
and select between a maximum of 7 static views.
design is incorporated or to which the design is
applied.
45
Interestingly, a recent decision from the UK Supreme
Court, PMS International Group Plc31, is notable for
stressing the importance of the images afxed in
the application form, for determining the scope of
Community design protection. As noted by Lord
Neurberger, when it comes to deciding the extent
of protection afforded by a RCD, the question “must
ultimately depend on the proper interpretation of
the registration in issue, and in particular of the
images included in the registration”32. Therefore, it
will almost always be the images that “exclusively
identify the nature and extent of the monopoly”
which the applicant is claiming33.
46
The case concerned an alleged infringement of a
RCD, which consisted of six images prepared by CAD
software of an item (a ride-on animal suitcase) whose
main body appeared as a uniform grey, but which
had black strips in the front, a black strap on the
top and black wheels. After analysing these images,
it was not clear whether the two-tone colouring
on the CAD images – i.e. the contrast in colour
between grey and black – was simply an artefact
of the computer-generated process or a visual cue
to indicate that the wheels and the strap should be
considered as separate components. The problem,
therefore, was whether the RCD was to be considered
as protection for the shape only, or for the shape in
two contrasting colours. Only in the latter case, the
overall impression created by this contrast in colour
could be considered.
47
It might be, therefore, that CAD representations
depict some unnecessary tonal contrast. This, in
turn, could generate confusion and be understood
as limiting the scope of design protection to certain
colours only.
48
The application for a RCD should also indicate the
products in which the design in intended to be
incorporated or to which it is intended to be applied.
In this respect, it is worth noting that product
classication mainly serves administrative purposes
and does not affect the scope of design protection34.
Once the design is registered, it is protected against
any use in relation to any product that does not
produce a different overall impression on the
informed user.
49 Once the request for registration is led, the EUIPO
carries out an ex ofcio examination of the two
absolute grounds for non-registrability, set forth in

Article 47 CDR. Namely, the Ofce veries whether
the subject matter of the application corresponds to
the denition of a design foreseen in Article 3(a) CDR,
and whether or not it is contrary to public policy
and accepted principles of morality. Therefore,
the registration procedure is kept to a minimum.
Compliance with the novelty and individual
character requirements will only be examined at a
second stage if a third party submits an application
for a declaration of invalidity.
50
It should also be noted that the EUIPO examines
whether the appearance of the “product” is disclosed
in the light of the design itself. Whether the product
is actually made or used, or can be made or used, in
an industrial or handicraft fashion, is not taken into
consideration35. In fact, there is no requirement to
submit a specimen of the claimed RCD.
51
This, in turn, implies that a person can: create a CAD
le for a product by means of CAD software; include
in the application for a RCD an image taken from
such a CAD le; obtain a design registration covering
the product design represented therein, irrespective
of whether the product is actually manufactured or
not.
52 This leads to the outcome that, although the entire
regulatory framework in EU design law is structured
on the concept of “product”, a design is protectable
regardless of whether a product comes into existence
or not. Accordingly, legal protection does not depend
on whether designs represented as CAD models exist
as tangible articles or not.
C. Unregistered design
protection of CAD files
53
An Unregistered Community Design (“UCD”) is based
on the same substantive provisions postulating the
validity requirements for a RCD. The meaning of
“design”, “appearance” and “product” are the same
for both RCD and UCD. As a general matter, any
design capable of being registered at the EU level
could also benet from the protection granted to
UCD.
54
There are, however, substantial differences between
RCD and UCD. A RCD confers a true monopoly,
whereas an UCD grants the right to prevent any
commercial use of a design that is an intentional
copy of the protected one. Yet, it should not be
demonstrated that the alleged infringer acted in
bad faith. Furthermore, a RCD confers protection
for up to 25 years, subject to renewal each ve years,
whereas an UCD affords protection for only three
35 Id., at 4.1.
years.
55
Protection of the UCD commences from the date
on which the design has been “made available to
the public” within the EU. As Recital 16 CDR puts
forth, there is no need to register products having
a short market life. A designer can introduce a new
design testing the market and le an application for
registration at a second stage. In fact, the designer
is entitled to register her design within a 12-month
period (“grace period”) from the date of the rst
disclosure. In other words, in the event that the
designer les an application for a RCD, disclosure
during the year preceding the date of ling shall not
be taken into consideration when appraising novelty
and individual character of the design in question,
pursuant to Article 7(2) CDR.
56 Let us now assume that a CAD le for a product to
which a design is applied is uploaded onto a website
which is a 3DP marketplace or repository. This, in
turn, raises a number of questions. Should the act
of uploading a CAD le onto an online 3DP platform
be tantamount to a disclosure of the design to the
public, which triggers UCD protection? Has the
design been “made available to the public”, and
become known in the normal course of trade? Has
the 12-month grace period commenced?
57
The following part of this paper detects the
circumstances under which a design shall be
deemed to have been made available to the public.
The phrase “made available to the public”, for the
purposes of identifying the date on which UCD
protection commences, is dened under Article
11(2) CDR. This provision mirrors Article 7(1) CDR,
which claries when a design has been disclosed
for considering questions of novelty and individual
character, for both registered and unregistered
designs. In fact, all designs made available to the
public, prior to the relevant date (indicated at Article
5(1)(a)&(b) and 6(1)(a)&(b)), are to be taken into
account to determine whether a design is new and
if it has individual character. This, in turn, raises an
additional question: should we consider all the CAD
models that have been previously uploaded onto
3DP online platforms as antecedent designs in the
prior art?
58 It should also be noted that a disclosure should take
place within the territory of the European Union
in order to create an UCD. Hence, UCD protection
is not afforded to designs that have rst been
made available outside the EU. On the contrary,
this requirement is not imposed under Article 7
CDR, which denes the notion of disclosure that is
relevant for determining the state of the prior art.

D. The concept of “made
available to the public”
59
Articles 7(1) and 11(2) CDR provide some guidance to
assess whether a design has been ‘made available to
the public’. This is the case if “it has been published
following registration or otherwise, or exhibited,
used in trade or otherwise disclosed”. The following
part of these provisions set forth the so-called “safe-
guard” clause, stipulating that a disclosure shall
not be taken into consideration if these events
(publication, exhibition, and use in trade) could
not have become known “in the normal course
of business to the circles specialised in the sector
concerned”, operating within the Community.
60
The EUIPO
36
’s case law from 2004 onwards allows
enough clearance on which acts constitute a
disclosure of a design to the public, which could also
become known in the normal course of business to
specialised circles.
61
A remarkable ruling that helps us to understand
better whether the publication of a CAD le on
an online platform would amount to a disclosure
to the public is the Board’s decision in Crocs, Inc. v
Holey Soles Holdings Ltd37. The holder of a RCD for
Crocs clogs, which was published in the Bulletin
of 8 February, 2005, conceded that the design had
already been published on www.crocs.com before
28 May, 2003. Nonetheless, the right owner argued
that such disclosure on the website did not destroy
novelty of the design in question, since it could not
have reasonably become known in the Community.
62
At that time, the website was unsophisticated and
virtually impossible to access. The website merely
functioned as an information tool for persons “who
might have learnt about the clogs from people
who had already bought them” and was not used
as a large mail order service. Websites that will be
regarded as a source of inspiration for developing
new designs are those of the established footwear
companies, such as Nike or Adidas, whereas Crocs Inc.
was not an established manufacturer at the relevant
date38.
63
The Third Board of Appeal dismissed the appellant’s
ndings. In the rst place, the Board found that the
Internet is a formidable information tool and is used
by designers in footwear as well as in other elds
as a resource in the development of their designs.
Moreover, Crocs website was an active website
36 Formerly called Ofce for Harmonization in the Internal
Market (“OHIM”).
37 OHIM Third Board of Appeal, decision of 26 March 2010 – R
9/2008-3.
38 Id., at 10(d).
already at that date and was congured to function
as a sales channel. Henceforth, the audience targeted
by the website was not only composed by those who
knew Crocs from before39.
64
Accordingly, when a design is published on a website,
it will per se be publicly disclosed and reasonably
become known in the normal course of business,
even if the circles specialised in the sector were not
aware of the website owner at that date
40
. This is
further conrmed in recent case law from the EUIPO.
As a matter of principle, information disclosed on
the Internet or in online databases forms part of the
prior art and is considered to be publicly available as
of the date the information was posted41.
65
Moreover, neither restricting access to a limited
circle of people (for example, by using password
protection) nor requiring payment for access (in the
same way as requiring a payment for subscribing to
a journal or purchasing a book) prevent a webpage
from being part of the prior art. The European circles
specialised in the sector concerned could reasonably
meet the accessibility requirement42.
66
A disclosure shall be deemed to be obscure and
irretrievable only in situations in which a design
disappears from mankind’s memory over time
and is available only in a local museum or traded
on a remote local market. This is not the case for
prior designs made available online. Users – either
the broad public or experts in a particular eld of
industry – use the service of web browsers, such as
Google or Yahoo, to search on the Internet. By using
keywords, they can easily nd websites dealing with
a particular subject matter. Therefore, once a design
is published on the Internet it becomes automatically
accessible and retrievable43.
67 For the purposes of applying Articles 5 and 6 CDR,
a disclosure could also take place outside the EU,
insofar as the design has become known in the
trade circles in the European Union. The question
of whether events taking place outside the EU could
reasonably have become known to persons forming
part of specialized circles in the EU is a question of
fact, dependent on the particular circumstances of
each individual case44. In theory, even where the

design has been disclosed to a single undertaking
within the EU, a disclosure of that kind may, indeed,
be sufcient for that purpose45.
68
Making a design available overseas, therefore,
may destroy novelty on the basis that Article 7(1)
CDR is not geographically restricted to the EU.
On the contrary, the same disclosure taking place
outside the EU may not be sufcient to commence
UCD protection, given the territorial qualication
contained in Article 11(1) CDR46.
69
It is therefore maintained that, in principle, the act of
uploading a CAD le onto an online platform should
be a sufcient ground for “disclosing” the design
represented therein, for the purposes of applying
Articles 5 and 6 CDR. A CAD le is retrievable and
easily accessible by Internet users, including experts
in the eld. This might be the case for both CAD les
that have been made available to the public, subject
to a Creative Commons licence, and those offered for
sale in 3DP marketplaces.
70
It follows that whether the design is new and has
individual character would need to be considered,
taking into account the already-available body of
designs, including all antecedent CAD les that have
been previously disclosed. In other words, product
designs embedded in CAD les that have already
been distributed online will form part of the state
of the prior art47.
71 The publication of the CAD le on a EU website can
also trigger UCD protection from the date of the
rst online publication, if the criteria for protection
(i.e. novelty and individual character) are met. The
designer would then have the option to register the
design within one year.
72
An unsettled issue is whether UCD protection is
activated if the CAD le is rst uploaded onto a website
that is hosted outside the EU (such as Thingiverse). If
the website is easily accessible by European users,
a positive answer may appear as more appropriate
in light of the above-mentioned case law, which
focuses on the retrievability of Internet publications,
whereas a literal interpretation of Article 110a (5)
CDR may suggest the opposite.

WS Teleshop International Handles-GmbH, decision of 11 July

46 See the decision of the German Federal Supreme Court of
October 9, 2008, Gebackpresse I ZR 126/06, [2009] GRUR 79.
47 More precisely, in order to pass the novelty and individual
character test, the design embedded in the CAD le shall
differ from all the designs made available before: the date
on which the le itself was published on the 3DP website,
with respect to UCD; the date of ling or validly claimed
priority, with respect to RCD.
73
It should also be noted that the CAD le made
available online should clearly reveal the outer
appearance of the product for which protection is
sought. Lacking a clear representation of the product
design, the act of publishing the CAD le on a website
will not constitute a relevant disclosure for the
purposes of Articles 7 and 11 CDR.
74
The option of making CAD les available online,
therefore, constitutes an interesting possibility
for those designers that want to prevent third-
parties from using their 3D models to obtain design
protection48. When the CAD le is disclosed, all later
designs will have to produce a different overall
impression on the informed user.
E. Requirements that a design has to
meet towards design protection
75
Articles 5 and 6 CDR state that a design has to be new,
has to have individual character, and must not fall
foul of any of the stipulated exceptions, in order to
enjoy design protection. These requirements will be
analysed in turn, focusing on the implications that
3DP carries.
I. Novelty and individual character
76 A design is new only when it differs materially from
everything that has been produced before. In fact,
Article 5(2) CDR states that differences between
two designs are irrelevant whenever they relate
to mere “immaterial details”. In this regard, the
novelty requirement is much closer to that for utility
patents, rather than the originality requirement
for copyright protection. It follows that users who
download already-existing CAD models from a 3DP
platform will have to modify them substantially in
order for their designs to be new.
77
In this respect, a critical issue that 3DP poses is
whether customized designs differ materially from
other designs that have been made available before.
Today, many companies, such as eMachineShop.com or
Shapeways, manufacture customized products based
on consumers’ CAD les. From an IP perspective, a
key issue is whether customized products provide
“added value” because they imprint true novelty,
or because they just enhance the value inherent in
the design of the core product. It may well be that
customized designs lack in novelty, since they differ
from the core product design in details that are
immaterial, banal or commonplace.

CAD Files and European Design Law
2016

78
Novelty and individual character overlap to a certain
extent. The main difference between these criteria
lies in the kind of examination carried out by the
EUIPO. When assessing novelty, the EUIPO makes a
comparison between the overall appearances of the
two designs. In contrast, when measuring individual
character, the EUIPO considers the overall impression
that the design produces on the “informed user”.
Therefore, any reference to the informed user is not
justied when assessing novelty. It is the Board’s
task to measure the differences between the designs
under examination on the basis of their overall
appearance49.
79
The test for individual character is less
straightforward and is likely to give rise to slightly
more subjective appraisals50. In Karen Millen
Fashions51, the CJEU held that, in order for a design
to be considered to have individual character, the
overall impression which that design produces
on the informed user must be different from that
produced on such a user “not by a combination of
features taken in isolation and drawn from a number
of earlier designs, but by one or more earlier designs,
taken individually”.
80
Therefore, the assessment as to whether the
product design embedded in a CAD le has
individual character must be conduced in relation
to individualised, dened and identied designs that
have been made available to the public previously.
81 Furthermore, in its recent decision in H&M Hennes &
Mauritz BV
52
, the CJEU held that the assessment of the
individual character of a Community design is the
result of a four-stage examination, which consists in
deciding upon: rst, the sector to which the products
belong; second, the identity of the informed user
of those products; third, the designer’s degree
of freedom in developing his design; fourth, the
outcome of the comparison of the designs at issue.
The designer’s degree of freedom cannot, on its own,
give rise to an outcome as regards the assessment of
individual character, but can only “reinforce” this
evaluation. The starting point should always be the
perception of the informed user.
82
The problem is how to carry out the four-stage
examination of the individual character requirement
with respect to CAD les. In order to be protectable,
a product design in the form of a CAD le should

produce an overall impression on the informed user
that differs from the impression produced by all
previous designs. Therefore, such a design will only
pass the individual character test if it differs from: a)
any CAD le for a product that has been previously
uploaded onto a 3DP platform; b) any product that
has already been marketed.
83
The situation is further complicated by the contention
that the informed user of an item represented as
a CAD le might need to be distinguished from
the informed user of the corresponding physical
product. Arguably, the former should be the user
of a 3DP platform, who wants to 3D print the item,
rather than the person who purchases the product
in a retail store.
84
Let us assume that a CAD le represents a bottle
opener, and that a later CAD le depicts a similar bottle
opener. In potential litigation, the informed user for
assessing the individual character requirement of
the disputed design could be: a private individual
who drinks wine; a professional (e.g. waiter or
sommelier); the user of a 3DP platform, who wants
to manufacture the bottle opener at home.
85 Therefore, a number of issues need to be addressed.
Who is the informed user of CAD les? How should
we evaluate the degree of freedom of the CAD le’s
designer? Will the individual character threshold
become less strict in the future if the market sectors
become overcrowded? The next paragraph suggests
some possible answers to these questions.
II. The “informed user” in the
3D printing landscape
86
For the purposes of this analysis, it is worth asking, in
the rst place, who would be the notional informed
user, if an increasing number of individuals engage
in the creation of CAD models and in digital-design-
le-sharing. Everyone can now design a product
from scratch by using CAD software. Users can also
download third parties’ CAD les and use online
tools to transform, adapt or recast the pre-existing
designs. Individual makers are both users and
designers. Hence, the following analysis suggests
that, if it becomes common practice that people
not only print but also design their own product at
home, the notion of informed user might need to be
revisited in the future. It argues that informed users
would tend to belong to the circles specialised in the
sector concerned, and resemble the “person skilled
in the art” in patent law.
87
The legal concept of “informed user” differs from
that of “average consumer” in EU trademark law.
The possibility of imperfect recollection on the
2016
Viola Elam
156
2
part of the average consumer plays a vital role
in trademark law, which is aimed at preventing
consumer confusion or deception. To the contrary,
design law protects the appearance of a product.
This implies that the informed user should not
merely half-remembering the articles but also have
a certain degree of familiarity with the item goods
in which the design is incorporated53.
88
Hence, according to established case law, the
informed user shall be particularly observant, aware
of the state of the art in the sector concerned, and
use the product related to the RCD in accordance
with the purpose for which the product is intended
54
.
The background knowledge of the items is certainly
higher than average, but not even too specic. She is
more than a mere consumer, but is less than a design
expert. Moreover, Lord Justice Jacob, in Procter &
Gamble Company v Reckitt Benckiser (UK) Limited55,
highlighted that the informed user is not the same
sort of person as the ‘person skilled in the art’ of
patent law. The equivalent to that person in the eld
of design would be some sort of average “designer”,
not a “user”.
89
Originally, the EUIPO’s Invalidity Division adopted
a rather different approach. The informed user was
found to be a person aware of the prior art known
in the normal course of business to “the circles
specialised in the sector concerned”. She does not
ignore the specic methods and techniques of
production56. For example, in a case concerning an
application for a declaration of invalidity of a RCD for
“wheels for bicycles”, the Invalidity Division found
that the informed user is aware of the requirements
that bicycle wheels must full in order to perform
their function. Therefore, the informed user also
“takes into account whether the degree of freedom
of the designer is limited by the requirement that a
wheel has to be laced with the spokes between the
hub and the rim and to transfer the weight of the
rider to the rim”57.
90 It thus seems that the notion of informed user was
once much closer to that of a design expert. The
Invalidity Division used to consider the informed
user as belonging the “circles specialised in the

sector concerned”. Nonetheless, as noted above, this
criterion should only apply when establishing what
is a relevant disclosure to the public, and potential
conicts with an already-existing design corpus,
under Article 7 CDR. The person of the informed
user, who is the reference for evaluating individual
character, shall not be part of any specialised circle,
lacking this sort or requirement in Article 6 CDR.
91
A correct interpretation of these two provisions
should be that a design is considered to have
individual character if the overall impression it
produces on the informed user differs from that of
an earlier design, which has already been disclosed
to the public. However, a design shall not be deemed
part of the prior art if not even the circles specialised
in sector concerned, operating in the territory of the
EU, are aware of its existence58.
92
Therefore, in a recent ruling, the Board of Appeal
found that the informed user of clogs is “neither the
manufacturer nor a seller of clogs, but the person who
wears clogs. Without being a designer or a technical
expert, the informed user knows the various designs
for clogs as a result of the relevant product range
offered in retail shops or over the Internet”59. In the
present context, footwear designers and footwear
industry, operating in the EU, represent the circles
specialised in the sector concerned.
93 This paper argues that 3DP may blur the distinction
between the notions of informed user and that of
design expert. Users may become more and more
aware of the specic methods and techniques of
production. If this is the case, one will have look at
early case law from the EUIPO in order to detect who
should be considered the informed user, in a new
ecosystem where the person of the designer and that
of the user conate to a greater extent.
III. How to evaluate the designer’s
degree of freedom
94 Following established case law from the EUIPO, the
designer’s degree of freedom is likely to be lower
if she has to comply with technical constraints.
Similarly, if a eld of application is already very
crowded, minor advances from the prior art might
produce a different overall impression on the
informed user60.
58 See, inter alia, opinion of Advocate General Wathelet, 5
September 2013, in case H. Gautzsch GroBhanden, supra note,

Man S.p.A. v Leng-D’Or S.A., decision of 4 November 2010,
at 20-21, found that the presence of so many shapes for
CAD Files and European Design Law
2016
157
2
95 On the one hand, when applying this reasoning to
3DP, one could maintain that the designer’s degree
of freedom will be gradually reduced. Assuming
that an increasing number of users and companies
will start producing and distributing their own
versions of CAD les, and that such les form
prior art, many market sectors will be thoroughly
soaked. If a specic sector is saturated, it inevitably
entails compromises, since minor differences in
the appearance of products might be enough to
lead to a different overall impression on the part of
the informed user. The appearance of a contested
design, therefore, might be very similar to that of an
earlier design and, nonetheless, lead to a different
overall impression.
96
Besides, it is worth considering that the designer
has to work within certain constraints in order to
make a 3D model suitable for printing. In the rst
place, there are some dimensional constraints.
The designer has to comply with height and size
requirements in order for the 3D printer to be used.
In other words, when designing the 3D model using
modelling software, the designer should take into
account that printed objects are limited by the
printers’ size
61
. Furthermore, a 3D model should have
a minimum thickness, at any given point (“minimum
wall thickness”), which depends on the material
used. Arguably, all of these technical constraints
limit the designer’s freedom.
97
On the other hand, one may argue that 3DP enhances
the designer’s freedom, since it enables the creation
of much more complex geometries, as opposed to
traditional manufacturing processes. Furthermore,
individuals have gained the capacity to design all
sorts of products with a relatively low experience.
It is also possible to nd tutorials on the Internet on
how to use modelling software, such as CAD software.
3D scanners enable the designer to digitize without
difculty any physical object. The newly-created 3D
model can then be modied, adapted and optimized.
98
Thus, it is questionable whether the designer’s
degree of freedom should be considered lower in 3DP
than in other design processes. This issue, however,
is dependant on whether the technology will or will
not become widespread. As noted above, for the time
being, individual users engaging in the creation and
“snacks items” is evidence of the broad possibilities open to
the designer and, at the same time, the limits thereof. The
designer freedom is not limitless, since the overcrowding
of the market sector and industrial feasibility of the goods
item determine much more constraint on a competing
company operating in the same market sector. Accordingly,
the designer’s degree of freedom was found to be average,
rather than broad or limitless, and implying a gradual
decline in the shapes that are still available.

F. Exceptions to Community Design
protection: the non-harmonisation
of the repairs clause
99 The scope of design protection for the appearance
of items represented as CAD les and the
corresponding 3D-printed products – is narrowed
by a series of exceptions, set forth in the CDR. The
rst functionality exclusion, provided in Article
8(1) CDR, states that a Community design shall not
subsist in features of appearance of a product, which
are solely dictated by its technical function. Such
features shall not only be necessary, but essential
to obtain a technical result. Thus, the level of
functionality required is higher than that provided
under trademark law.
100
In a way, such exclusion emulates the idea and
expression dichotomy in copyright law. In fact,
in the 1991 Green Paper on the Legal Protection
of Industrial Design62, the European Commission
made clear that if the designer has a choice among
various forms, in order to arrive at the technical
effect, the features in question could be protected.
This, in turn, means that features of appearance
of a product, represented as a CAD le, will not be
granted protection if they are only indispensable
for achieving a specic technical result. It does
not follow, however, that the whole design will
automatically be denied protection.
101 Over and above the general exclusion of “technical
function”, Article 8(2) CDR provides the so-called
“must-t” exception or “interface” exclusion. This
exclusion is aimed at enabling technical replacement
products and ensuring mechanical interoperability.
Hence, no protection is given to those features that
must necessarily be reproduced in their exact form
and dimension in order to permit the product, in
which the design is incorporated, to be mechanically
connected to another product (for example, exhaust
pipes or coupling sleeves are examples of “must t”
designs in the automotive industry). This permits
the possibility that either product may perform its
function.
102
This provision turned out to be rather redundant,
insofar as spare parts, which are not visible in
normal use63, and those that are solely dictated by
their technical function, are anyway excluded from
design protection64.

One of the most problematic issues the EU legislators
had to face concerns the so-called “must-match”
exclusion65. This exclusion deals with the visual
synchronisation and aesthetic appearance of a
complex product, rather than with functionality. In
other terms, the must-match provision concerns the
design of a component part, which should be used for
the purpose of the repair of a complex product so as
to restore its original appearance (e.g. the design of
a car body panel that is used to restore the original
appearance of the vehicle).
104
The protection of must-match spare parts has
occasioned the greatest controversy among a wide
range of stakeholders, especially in the automotive
industry. The following analysis provides a brief
overview of the legislative history on this issue. This
will help explain why the dispute is not resolved yet.
105
The original idea in the 1993 proposals for a
Regulation on the Community design66, and for a
Directive on the legal protection of designs
67
, was
to introduce a must-match exception in Europe,
specifying that only after a period of three years,
from the rst placing on the market of a complex
product, the rights conferred by a RCD could not be
exercised to prevent third parties from using the
design of a component part, in order to restore the
original appearance, or to permit the repair of, the
complex product. The Council of Ministers rejected
this option.
106
The European Parliament advanced a different
solution in the Amended Proposal for the Design
Directive, opting for a compulsory licensing regime
that allowed the use of component parts, for repair
purposes, immediately after the placing on the
market of the complex product, in exchange for a fair
and reasonable remuneration of the right holder68.
apply to design features which allow the multiple assembly
or connection of mutually interchangeable products within
a modular system (Recital 11, Article 8(3) CDR). Hence,
design subsists in interconnection features of construction
toys or modular furniture. Cornish et al., in Intellectual
Property: Patents, Copyright, Trade marks and Allied rights, 7th
edn Sweet & Maxwell (2007), p. 613, maintain that the special
treatment offered to toy manufacturers has no reasonable
explanation, except that it shows how determined lobbying
can squeeze special concessions into legislation.
65 The “must-match” terminology comes from the UK
legislation on UK Unregistered Design Rights. Such
exception was rst introduced within the UK Community
Designs and Patents Act 1988.

68 Amended Proposal Design Directive [1996] OJ C1 42/7,
Article 14.
Manufacturers of component parts were required to
inform the public as to the origin of their products
used for the repair by means of a trademark or trade
name. They also had to notify the right holder of
the intended use of the design, and regularly inform
her as to the scale of such use. Nonetheless, no
agreement on the compulsory licensing clause was
reached by the European Council.
107
Ultimately, the disagreement between EU institutions
was the subject of a Conciliation Committee meeting,
where the Council insisted on its position against
a remuneration scheme. It recommended, instead,
an extension of the period of exclusivity over
component parts for a period ranging from three
to seven years.
108 In such a tense context, the European Union opted
for the so-called “freeze plus” solution, stating that
until amendments to the Directive are adopted on
a proposal from the Commission on this subject,
Member States shall maintain in force their existing
legal provisions. Member States should only change
their laws if they wished to liberalise their market
for spare parts, pursuant to Article 14 Directive
98/71/EC. Therefore, Member States had alternative
options: they could introduce a clause allowing
any use of the design for repair purposes; adopt a
remuneration system; provide a term-limited design
protection; or craft their own exception, which is a
combination of the second and third options.
109
Article 110 CDR codied another “freeze plus” or
transitional provision, mirroring the one set forth
in the Directive. Thus, in 2004 the Commission
made its third attempt to achieve harmonisation in
this convoluted area, issuing a proposal designed
to liberalise the aftermarket for spare parts69. This
proposal, known as the “repairs clause”, purported to
increase legal certainty and allow market operators
and consumers to take full advantage of a uniform
Internal Market for spare parts70.
110 In fact, the situation at that time was characterised
by opposed regimes, where nine Member States,
including Italy and the UK, have liberalised, whereas
sixteen Member States had de jure design protection
to spare parts (among them, Austria, Denmark,
Finland, Germany, Portugal, Sweden). The European
Commission found that the status quo – with mixed
protection regimes of design protection for spare
parts – was altogether unsatisfactory and created
trade distortion in the Internal Market71. The non-

harmonisation of the must-match exclusion means
that independent manufacturers are only able to
sell their products and offer their services in some
Member States but not in others.
111 Following a lack of progress at Council level, in May
2014 the proposal was withdrawn. Successively, the
Commission launched a comprehensive legal and
economic evaluation of the overall functioning of EU
design systems72. In the framework of this evaluation,
an external contractor, Europe Economics, presented
“The Economic Review of Industrial Design in
Europe”73. The latter suggests that, among various
policy options, full liberalisation, meaning a complete
elimination of design protection for spare parts
within the EU, would be the best outcome. In an age
of widespread availability of 3D printers, consumers
and independent manufacturers think that they are
entitled to produce their own 3D-printed spare parts
for the purpose of repair. Hence, a de facto repairs
clause might become inevitable anyway. Insofar
as it is impossible to enforce design law against all
infringers in the 3DP landscape, a full liberalisation
has to take place.
112
In response to this argument, one could maintain
that 3DP makes the introduction of a repairs clause
a more delicate issue than it was in the relatively
recent past, because 3D printed products might not
meet quality and safety standards. Any proposal
for full liberalisation should foresee a method to
ensure that component parts are safe and useable,
when it becomes possible for different industries to
manufacture spare parts using 3DP.
113
In a study commissioned by the UK Intellectual
Property Ofce (“IPO”), Reeves and Mendis stressed,
in this regard, that it is rather unrealistic to assume
that 3DP will be heavily used, in the near future,
to make component parts in certain industrial
sectors, such as the automotive aftermarket74. The
component parts that, according to the UK IPO’s
study, are not yet suited to additive manufacture
include: tyres, batteries, oil lters, air conditioning,
etc. There are also aftermarket parts whose
manufacture is technically possible by means of 3DP,
but not economically viable yet, since the production
costs would be higher than the current aftermarket
value. The latter include: exhaust pipes, distributor
caps, water pumps, and radiators75.
72 See
industrial-design/protection/index_en.htm>.
73 Europe Economics, The Economic Review of Industrial Designs
in Europe, a study commissioned by DG Internal Market and
Services (January 2015).

Current Status and Impact of 3D Printing Within the Industrial
Sector: An Analysis of Six Case Studies (March 2015), p. 19.
75 Id., p. 17.
114
As noted by the authors, one of the biggest limitations
to the production of 3D printed spare parts lies in the
lack of credible design data from which to print. In
the Ofce’s opinion, it is erroneously “assumed that
parts can be simply scanned and reverse engineered,
with the resulting data then being stored on the
cloud” for downstream 3DP. It is of fundamental
importance to have access to the original CAD les,
to understand “issues such as tolerances, loading
conditions and material requirements”.
115
Hence, whether the impact of 3DP on the liberalisation
of the aftermarket sector will be signicant in the
next future is not altogether clear yet76.
116
For the sake of completeness, it is also worth recalling
a recent Order from the CJEU in Ford Motor Company v
Wheeltrims s.r.l.77, dealing with trademark law.
117
At rst instance, in the Italian proceedings, the
claimant Ford Motor Company claimed that the
defendant, a company operating in the automotive
aftermarket, had infringed its registered trademark
“Ford”. Wheeltrims was marketing wheel caps
bearing the registered trademarks of the original
manufacturers – including Ford’s trademark –
without the owners’ authorisation. The defendant
raised the repairs clause defence, arguing that
Article 241 of the Italian Industrial Property Code,
implementing Article 14 of the Design Directive,
should apply as a defence to trade mark infringement.
The use of the trademark “Ford” was justied for the
purpose of restoring the original appearance of the
complex product, in derogation of the Trade Mark
Regulation (EC) 207/2009 and Trade Mark Directive
84/104/EC. The Tribunale Ordinario di Torino made
a reference for a preliminary ruling to the CJEU on
the interpretation of the repairs clause set forth in
the DD and CDR.
118
The CJEU answered the referred questions by Order,
stating that Article 14 of DD and Article 110 CDR must
be interpreted as not allowing – by way of derogation
from the provisions of the Trade Mark Directive
2008/95/EC and Trade Mark Regulation 2009/207/
EC– a manufacturer of replacement parts and
accessories for motor vehicles to afx to its products
a sign, which is identical to a trademark registered
for such products by the original manufacturer,
without the latter’s authorisation, on the ground
that the use thus made of the trade mark is the
only way to restore the original appearance of the
complex product.
119 Hence, the CJEU has made clear that, in its current
76 According to Reeves and Mendis it will not be signicant for
the next 10 years. Id., p. 20.

form, the repairs clause that is anchored in European
design law does provide a defence to an alleged
trademark infringement. As a result, a third party
who replicates by means of 3DP a component part, to
which the manufacturer’s own trademark is afxed,
may be found liable for trademark infringement,
provided that the private use exception does not
apply78.
G. Exclusive rights conferred
by a design
120
In the event that a design is registered, the holder of
a RCD is granted an exclusive right to use it and to
prevent any third party not having her consent from
using it. Pursuant to Article 19 CDR, the right to use
the design covers different sorts of activities, such as
the making, offering, putting on the market or using
of a “product” in which the design is incorporated.
In contrast, an UCD confers the right to prevent the
same aforementioned activities, but only insofar as
the contested use results from copying the protected
design, and is not the result of an independent work
of creation.
121
The owner’s exclusive rights extend towards any
third party, without any differentiation between
primary and secondary infringers. This, in turn,
implies that the holder of a RCD can pursue claims
for direct infringement against intermediaries (e.g.
online 3D platforms).
122
Furthermore, as already mentioned, infringement
is not conned to the use of the design on the same
product, in which the design was incorporated in
the rst place. Protection extends toward any use
of the design, in relation to any products. It is also
worth remembering that infringement cannot
occur with respect to acts done privately and for
non-commercial purposes79, and acts done for
experimental purposes (Article 20 CDR).
123
In light of the above considerations, the question
of whether 3D printing a design-protected product
from a CAD le constitutes or not an infringing
activity is straightforward. There is no doubt that the
acts prohibited under Article 19 CDR will encompass
the manufacture of objects via 3DP, that is done in
the context of a commercial activity and outside the
78 According to Article 10 of Directive 2015/2436/EC, in
order to commit an infringement the use of a third party’s
trademark should be “in the course of trade”, i.e. in the
context of a commercial activity with a view to economic
advantage and not as a private matter. See the CJEU’s ruling
in Arsenal Football Club plc. v Reed, C-206/01 [2002] ECR
I-10273, [40].
79 These criteria are cumulative. Use should be both private
and for purposes that are not commercial.
scope of the private use exception (i.e. “making”
the design)
80
. Infringement will not be actionable,
instead, against an individual, who 3D prints a design
product at home, for private and personal use.
124 Moreover, the fabrication of products, by means of
3DP, done for scientic research will be exempted,
irrespective of whether it is for a private or
commercial purpose81. As noted by Suthersanen,
this exception should be interpreted narrowly and
be only allowed if the experimental usage of the
design is in the general interest. A demarcation
should always be made between acts of experimental
nature, and those that seek to exploit the design82.
125 Whether the scope of design protection should also
include the act of making a scanned representation
and/or a CAD le from a design already existing
as a tangible article is less clear-cut. Also, does the
unauthorized act of copying and marketing a third
party’s CAD le, in which a design is incorporated,
amount to infringement of the design right?
126 The unsolved issue, therefore, is whether activities
carried out in relation to CAD les fall foul of Article
19 CDR, and constitute an illegitimate “use” of the
design. Moreover, who is the party responsible for
the infringement: the one who uploads, downloads
or markets the CAD le? Should the host of the le-
sharing site be held liable too?
127
A strict interpretation of the law would suggest that
the answer to these questions should be no. Just as a
design requires there to be a product, infringement
should only occur where a person uses a physical
product83. The latter should not necessarily be the
same product to which the design was incorporated
in the rst place, but it should however be an
industrial or handicraft item.
128 Furthermore, the CDR does not provide protection
against indirect use of a design, differently from
patent law. There is no specic provision that confers
on the holder of a Community design the right
to prevent third parties, not having her consent,
from supplying the “means” for using the design
(e.g. marketing a complete kit that, when made up,
constitutes the design)84. A CAD le could be seen as
a “means” enabling the fabrication of the product in
which the design is incorporated. As a consequence,

making and distributing a CAD le would constitute
an authorized (indirect) use of the design85.
129
Therefore, a crucial issue to address is the extent
to which a design right can be used against a new
form of exploitation that does not imply the making
of physical objects, but the creation and sharing of
digital les.
130
It is here suggested that conning the scope of
design protection to use on material products only
is overly restrictive, in the light of the current
technological change brought about by 3DP. This
technology is blurring the line between the physical
and the immaterial worlds. An increasing number
of undertakings might decide to make their CAD
les available online in the course of their business.
Digital networks might emerge as an ordinary means
of distributing 3DP templates of protected designs.
In this way, undertakings would not need to mass-
produce or distribute their products any longer.
131 Once a design is made available in the form of a CAD
le, it then becomes extremely easy for anyone to
replicate it, either by entrusting a third party with
the task of printing the product, or by using personal
hardware. Future advancements in personal 3D
printers will further expand this capability. Hence,
design-based industries have to be equipped for
the digitalization of things. In order for alternative
business practices to come to light, it is of utmost
importance to ensure that material protected by an
IP is respected.
132 This, in turn, calls for a reinterpretation of the legal
basis on which right holders shall receive protection.
Arguably, they should be exclusively entitled to use
– and prevent third parties from using and dealing
with – the CAD les of their protected designs.
133
There are several ways to address this issue.
A rst option would be to consider the digital
representation of a design as a “product” within
the meaning of Article 19 CDR. Accordingly, this
provision would cover different activities, such
as the unauthorized making of CAD les (i.e. the
making of a product), sharing of CAD les with other
Internet users (i.e. use of the design), and the sale
of CAD les on 3DP marketplaces (i.e. offering the
product and putting it on the market). Furthermore,
a possible interpretation of Article 20 CDR would be
that the private use exception exempts from liability
a third party who simply downloads a CAD le and
saves it on her computer.
134
One may support this conclusion arguing that
requiring products to have some physical form would
85 Bently, Sherman (2008), supra note 83, p. 666.
be unduly limiting
86
. From a systemic perspective,
it seems rather contradictory to allow registration
of graphic symbols – including computer icons –
and, at the same time, postulate that the notion
of “product” is tied to a physical dimension for
infringing purposes.
135 Furthermore, the scope of design protection is not
limited to a certain category of products; rather, it
covers any use of the design, in relation to “any”
product that does not produce on the informed
user a different overall impression. As noted by
Malaquias, it seems very difcult to ascertain that
a CAD le “will produce on the informed user a
different overall impression from the protected
design, considering that its purpose is to replicate
the existing design in three-dimensions”87.
136 In the opinion of the present writer, the preferable
solution is to follow the recommendation, made
by the European Commission in the “Legal Review
on Industrial Design Protection in Europe”88, to
introduce an infringement provision stating that
the creation of a design document amounts to an
infringing use89.
137
As suggested by the European Commission, a
template for such provision may be Section 226(1)
of the UK CDPA 1988, which states that “the owner
of a design has the exclusive right to reproduce
the design for commercial purposes [...] by making
a design document recording the design for the
purposes of enabling such articles to be made”.
138
In the UK jurisdiction, “design document” is
dened in Section 51(3) CDPA as: “any record of a
design, whether in the form of a drawing, a written
description, a photograph, data stored in a computer
or otherwise”. The scope of this provision is wide
enough to include CAD les as design documents90.
139
Furthermore, EU design law could fashion an
additional provision similar to Section 226(3) CDPA
1988, specifying that it is a primary infringement
of a design right to do or “authorise” another to
do, without the design right owner’s permission,
86 This expression is used by Bently and Sherman, id., p. 667,
footnote 66.
87 Malaquias (2014), supra note 80, p. 27.
88 MARKTD2014/083/D.
89 Id. 133.
90 It should however be borne in mind that in the UK
jurisdiction, pursuant to Section 51(1) CDPA 1988, copyright
in a design document (i.e. in the CAD le) will not infringed
by making a 3D article from it, where the design is for
anything other than an artistic work or a typeface. Hence,
if a CAD le embodies a utilitarian design (for example,
the design of automotive spare parts), printing the object
will not result in copyright liability. In this respect, the UK
model would not be a good model to replicate for the EU.

anything which is the exclusive right of the design
right owner.
140
In the rst place, this provision would clarify
that making a CAD le from an existing design-
protected product, for the purposes of 3D printing
such product, amounts to an infringement of the
design right. This provision would also specify that
intermediary parties (such as 3DP online platforms)
might also be directly liable for “authorising” design
infringement. As stressed in the Commission’s
review, the benet of such a provision is that
neither actual nor constructing knowledge would
be required for a positive nding of infringement91.
H. Conclusions
141
A clear message emerges from the arguments
developed in this paper. European design law
should adapt to the reality of digitized goods and
accommodate greater protection for right owners.
142
To date, the EUIPO accepts 3D digital representation
of designs as “representations of the design that are
suitable for reproduction”, within the meaning of
Article 36 CDR. Such a representation is enclosed
in the application form for a RCD to show, in the
same way as a photograph, the design for which
protection is sought.
143
It has also been noted that, although the CDR is
structured on the concept of “product”, the EUIPO
does not take into consideration whether a product
is actually made or used, or can be made or used, in
an industrial or handicraft fashion. This, means that,
in theory, the CAD representations included in the
application for a RCD will determine the scope of
design protection, regardless of whether the product
is actually manufactured or not.
91 As an alternative remedy, the European Commission
proposes to introduce “indirect design infringement” as a
separate head of liability. As noted above, a CAD le may
be seen as a “means” that enables the actual infringement
of the design right, i.e. as an “indirect” use of a design.
In addition, the European Commission focuses on the
possibility to review the private and non-commercial use
exception. One way to restrict the scope of this exception
is to employ the 3-step language adopted in Article 26
of the TRIPs Agreement (“provided that such exceptions
do not unreasonably conict with the normal exploitation of
protected industrial designs, and do not unreasonably prejudice
the legitimate interests of the owner of the protected design,
taking account of the legitimate interests of third parties”), in
order to provide greater exibility and achieve a balance
between the legitimate interests involved. The latter
recommendation does not seem advisable. The language
employed in the three-step test may lead to ambiguity and
to a non-uniform interpretation. Rather than representing
a useful tool, it may create additional confusion. Cf. 6.1 of
the report (MARKTD2014/083/D).
144
It has also been contented that in case a CAD le
clearly unveils the outer appearance of a product,
its publication online will be tantamount to a
“disclosure” for the purposes of Article 7 CDR. As a
consequence, all later products – and CAD les for
products – will have to produce a different overall
impression on the informed user. By contrast, it is
not entirely clear whether publishing a CAD le on
a website that is hosted outside the EU will trigger
UCD protection from the date of the rst online
publication, given the geographical limitation
contained in Articles 11 and 110(a) 5 CDR.
145
Hence, there are many issues that have to be
claried. First, who is the informed user of a product
represented digitally as a CAD le, as opposed to the
informed user of the nished product? Second, is the
designer’s degree of freedom enhanced or limited
by the fact that she creates a product design using
CAD software? Third, if many individuals begin to
create their own CAD les for products and upload
them online, thereby disclosing the design for which
protection is sought, will many market sectors
suddenly become overcrowded? Will all subsequent
designs have to depart from the considerable amount
of CAD models already made available online?
146
Besides, the ease of converting a CAD le into a
physical item leads us to suggest that design owners
should be entitled to claim protection for the CAD
representations of their designs. In a hypothetical
world of widespread 3D printers, it could be that
CAD les become almost interchangeable with
end products. The owner of a CAD le might be as
satised as if she possesses the end product itself. A
CAD le would then serve as a substitute for a good,
offered to the same or actual potential customers.
147
Many are the elds in which clear-cut rules are
needed, since new technologies empower the
individual in her creativity and yet should make
her responsible for potential infringement of third
parties’ exclusive rights.
148
In this respect, the present writer supports the
following recommendations, made by the European
Commission in its recent report “Legal Review on
Industrial Design Protection in Europe”: rst, to
introduce a provision that confers upon the design
right owner an exclusive right to make a design
document, which is a record of the design (i.e. a
CAD le); second, to introduce a provision on direct
primary infringement by authorisation.
