What is the PCT system?
The PCT system is based on an agreement that encompasses over 130 states. According to the agreement, an applicant can file an international patent application, i.e. a PCT application, in which he may designate all signatory states. The novelty and inventive step of the invention disclosed in the international application are examined centrally, and the applicant receives an opinion on the patentability of the invention. Within 30 months from the priority date, the applicant must file national and/or regional applications in the states and regions where he wishes to pursue the application further. The advantages of the PCT system include, on the one hand, the central processing of the application and, on the other hand, the postponement of the costs associated with national and regional applications to a time when the patentability and economic value of the invention will be better known.
