What is the PCT system?
PCT is an international patent application filing system set up by the Patent Cooperation Treaty 1970 and managed by the World Intellectual Property Organization (WIPO). This is to facilitate an international patent application and make the process more accessible to applicant's from member states and an applicant will only be required to initially file only one application for all the intended countries.
At present (information at 14 January 2010) the Patent Cooperation Treaty has 142 member states and Thailand became the 142nd member of the Patent Cooperation Treaty on 24 December 2009
Thailand implemented the provisions of the Patent Cooperation Treaty through a Ministerial Regulation on Patent Applications. This regulation was in accordance with the Patent Cooperation Treaty 1979 and Section 17 of the Patent Act 1979. The ministerial regulation set out the principles and application procedures in order for an applicant to file an international patent application in the Patent Cooperation Treaty member state by filing the patent application with the Department of Intellectual Property.
