PCT Filing

The PCT filing is filing of a patent application under the Patent Cooperation Treaty (PCT). PCT is an International patent law treaty, and provides a unified and standard procedure for obtaining patent rights and protection of new inventions in one or more of its contracting states. PCT is operated by the World Intellectual Property Organization (WIPO). Established in the year 1970, the Patent Cooperation Treaty has presently (till June 2011) a total of 144 contracting States.

A single patent filing (PCT filing) is made at the Receiving Office (RO). On receipt of the PCT filing the patent search is carried out by the International Searching Authority (ISA) or optionally by the International Preliminary Examining Authority (IPEA), for drafting a written opinion regarding the patentability of the invention filed through the PCT filing. After this, the patent application or PCT filing enters into the national or regional phases, and the national or regional authorities handle the processes of the examination of the patent application and the grant of a patent. In general, after 30 months from the PCT filing at the RO, or from the earliest priority date of the application (if the application possesses a priority claim), the patent application enters into the national or regional phases.
