What Are the Two Phases Involved in Applying for an International Patent?
International Phase
Upon the application for the International PCT, your national application may claim a priority date. During this step, an International Search Report is obtained and an International Publication Occurs. The maximum duration of this internationalization is 18 months.
National Phase
The national application is the first step in receiving a PCT patent. This phase includes a formal presentation to the PCT office in the product´s country of origin and in those additional countries where the applicant seeks a patent—or those recommended by the International Search Report. For Spanish applicants, this application phase must begin before the 30th month following the filing of the Spanish patent.
