Signed in 1970 in Washington, USA, The Patent Cooperation Treaty (PCT) was created to align the patent application for a new invention or optimization in several countries.

With 153 current signatory nations, the agreement has included Brazil since 1978. To be entitled to register a patent on a global scale, the applicant must first apply for registration in one of the countries that are part of the agreement, or at the office World Intellectual Property Organization (WIPO) in Geneva. In Brazil, the responsible body is the INPI, National Institute of Industrial Property.

For the patent application to be properly extended to abroad, it is necessary to go through two distinct phases: the national registration in the country of origin, following all the national laws of the body in question and, later, the international process (through PCT or direct filing in the countries of interest).

Choosing to file the patent internationally using PCT, the patent application will pass through an International Search carried out by the INPI (in the case of a patent filed in Brazil) and a report will be issued on the existence of international priorities regards to the patent application as well as a written opinion with formal evaluation of the patent application. It will be analysed: inventiveness, industrial applicability, novelty, reports descriptive and figures.

It is worth remembering that both national and international requests have fees and deadlines for analysis and eventual approval, as well as mandatory completion of specific forms at each stage. For the international phase, the application for patent registration must be in one of the following languages accepted by WIPO: German, Arabic, Chinese, Spanish, French, English, Japanese or Russian.
