International filing strategies should take into account not
only what to file for and in which countries – but also
where the first application should be filed.
The following discussion focuses on choosing whether to file a

If an applicant does take the route of filing in the United

reasons because this could affect filing strategies in other
We recommend to clients that if they wish to file a US patent
