PCT International Application

PCT International Application

PCT (Patent Cooperation treaty) is international treaty through which an application for patent can be filed in multiple countries on the basis of single application made before PCT. This treaty is administered by world Intellectual Property Organization (WIPO). Currently, there are around 157 contracting members in PCT.

Since the patent rights are territorial in nature; therefore, separate applications for patent are required to be made in countries where the applicant is willing to protect the invention. On the other hand, filing multiple applications before patent authorities of countries of interest within twelve (12) months from the priority date (as per Paris convention route) impose undue hassle to the applicant, such as:

  • The applicant is required to arrange a huge fund for filing patent application before multiple patent offices (including official fee as well as local Attorney fee);
  • The applicant is required to ensure that all such applications pertaining to the same invention be filed simultaneously; and
  • The Applicant can not extend the patent application to additional countries.

PCT International application is devoid of these disadvantages and offers certain advantage which makes PCT International application a better route for filing patent applications in foreign countries. These advantages are:

  • The PCT International application is deemed to be filed before each and every patent office of its member countries; provided that a national phase application is filed within an extended period. Thus, there is no hassle to manage simultaneous filing before multiple countries; instead, a single window is available for filing patent application in multiple countries;
