The PCT international application is a patent filing framework established by the Patent Cooperation Treaty (PCT). Through this mechanism, an applicant can file a single application with a receiving office and simultaneously seek patent protection across the treaty’s member states. Compared with traditional country-by-country filing, a PCT application streamlines procedures and also buys extra time to evaluate target markets, find partners, and prepare for entry into each jurisdiction’s national phase.

        In the international phase, the application undergoes a formalities check and an International Search, with the option to request an International Preliminary Examination. These steps provide important reference information so that, before entering the national phase, the applicant can better assess patentability prospects and commercial value.

        With extensive practical experience, our services cover: drafting and translation of application documents, responses during the PCT international search/examination process, and coordination with local associates for national-phase entries. With the support of a professional team, applicants can efficiently build a global patent portfolio to protect their innovations.
