PCT System is a tool which helps protecting Inventions abroad and based on the Patent Cooperation Treaty (PCT). PCT is international treaty with more than 150 Contracting States. This system makes it possible for patent owner to protect theirs invention simultaneously in a large number of country by filing only one international application instead of national or regional submitting, normally through the support of IP attorney.
However, the patent is granted under the control of national or regional patent offices via national phase. The application when filing by this system is called PCT application. The general PCT procedures includes: filing application; international search; international publication; supplementary international search (optional); international preliminary examination (optional); national phase.
PCT is widely used by individuals and different organizations. Patent owner is entitled to file PCT application if they are a national or resident of a PCT Contracting States. If there are several applicants named in the international application, only one of them needs to comply with this requirement. Also, the PCT application can be filed, in most case, with national patent offices or directly with WIPO if pursuant to national law.
One of the most important matters which applicant notice is the time schedule when filing PCT application. Normally, applicant will have up to 18 months from the time they file their international patent application (or usually 30 months from the filing date of the initial patent application of which they claim priority) before they enter national phase with the separate procedures of each national patent offices. Be noted that you always can ask for an early entry into the national phase without waiting for the expiration of 30 months.
During the time period of PCT process, the PCT application will be gone through an international search which is the main search beside supplementary international search, by International Searching Authorities which may be either a national office or an intergovernmental organization, such as the International Patent Institute, whose tasks include the establishing of documentary search reports on prior art with respect to inventions which are the subject of applications, with the result of an international search report. The report enable applicant to evaluate the chances of obtaining patents in national phase. After that, the application will be published or this step called International publication. WIPO (World Intellectual Property Organization) publishes the international application shortly after the expiration of 18 months from the priority date together with the international search report on PATENTSCOPE. After the international publication, applicant can also request for a second evaluation of the potential patentability of the invention which is International preliminary examination. This examination allows applicant to amend the international application before entering the national phase. At the end of the procedure, an international preliminary report on patentability will be issued. This report give the opinion on the compliance with the international patentability criteria of each of the claims which have been searched and an even stronger basis on which to evaluate the chances of obtaining patents.
Finally, you may decide to push your application go further when proceeding with national phase. From that time, the procedures would comply with the national where it is elected or designated.
