PCT Patent Filing & National Phase Entry Services

International Patent Filing, PCT Route and India Entry Support

PCT Patent Filing allows applicants to seek international patent protection through a single international application under the Patent Cooperation Treaty. A PCT application does not itself grant an “international patent,” but it helps applicants preserve rights across multiple countries while giving additional time to evaluate markets, funding, licensing, and national filing strategy.

The PCT procedure generally begins with an international application filed through a competent receiving office or directly with WIPO, followed by international search, publication, and later national or regional phase entry in selected countries. WIPO explains that PCT filing allows an applicant to file one international application in one language and pay one set of fees at the international filing stage.

AJ & Partners supports clients in Indian PCT filing, PCT national phase entry into India, and foreign national phase / convention-route coordination with careful attention to documents, deadlines, priority details, and procedural requirements.
