Where to file your PCT application?

Applicants who wish to file an international PCT application have to use the national office (which acts as a Receiving Office) in the country of which they are a national or resident or the International Bureau as a Receiving Office.

Requests for the Visegrad Patent Institute to act as an ISA should be filed at the Receiving Office of the Industrial Property Office of the Czech Republic, the Hungarian Intellectual Property Office, the Patent Office of the Republic of Poland or the Industrial Property Office of the Slovak Republic. The applicant must indicate the Authority chosen in the appropriate space in Box No. VII in the Request form.
