An international patent filing procedure that helps applicants reserve time and coordinate patent protection before entering selected national or regional phases.
The Patent Cooperation Treaty (PCT) is used where patent protection may be needed in several countries, but the final filing geography, budget allocation or commercial priorities are not yet fixed.
It is important to understand that the PCT does not grant an “international patent”. Instead, it simplifies the filing process and creates a coordinated international phase before national or regional offices decide whether patent protection should be granted.
Final decisions on patent grant are always made by national or regional patent offices under their own laws and procedures.
The PCT procedure is usually chosen where international protection is planned but the final list of countries, budget allocation and commercial priorities are not yet fixed.
One international application can serve as the starting point for patent protection in multiple countries.
Major patenting costs are postponed until national or regional phase entry.
The system gives additional time to analyse markets, evaluate the invention and choose countries strategically.
The applicant receives an international search report and written opinion that help assess patentability prospects.
The route is useful where international protection is planned but the final list of countries is not yet fixed.
The system is widely used by corporations, research institutions and technology companies.
The PCT procedure usually includes three main stages, from the first filing to continuation in selected national or regional jurisdictions.
Important: Optional steps may also be available at this stage, including supplementary international search and international preliminary examination.
Important: By this stage, the applicant already gains a practical understanding of the invention’s patentability prospects and can make an informed decision on whether continuing the procedure in specific countries is commercially justified.
From that point onward, the application is examined under the laws and procedures of each selected jurisdiction, and patent grant is decided there.
First priority application is filed.
International PCT application is filed.
International Search Report is typically issued.
International publication of the application takes place.
Entry into selected national or regional phases.
Where the invention is intended for protection in several countries.
Where the applicant is not ready to incur separate national filing costs immediately.
Where more time is needed to assess markets, investors and licensing prospects before large-scale filing.
PCT is a filing procedure, not a single patent right.
National or regional phase entry deadlines must be monitored carefully.
The value of the PCT procedure depends heavily on selecting the right jurisdictions for continuation.
We support the PCT procedure from initial strategy and filing through analysis of international reports and national phase planning.
We prepare and file the international application.
We manage communication and procedural steps during the international phase.
We analyse the international search report and written opinion.
We help determine in which countries or regional systems the procedure should continue.
We coordinate continuation in selected jurisdictions through our regional and international practice.
