We know that Japanese patents, like China patents, are divided into three types: invention, utility model and design patent. With the deepening of Sino-Japanese exchanges and the purpose of exploring patent value, more and more patent owners apply for Japanese patents, but where can they apply for Japanese patents? What are the ways of Japanese patent application? Bian Xiao answered your question in the following article. Where can I apply for a Japanese patent? What are the ways to apply for Japanese patents? There are three main ways to apply for Japanese patent, namely, Patent Cooperation Treaty (PCT), Paris Convention and directly submitting patent application to Japan Patent Office (JPO). 1, Patent Cooperation Treaty (PCT) Ways According to the patent cooperation treaty, the applicant can submit a PCT international patent application to the international patent application acceptance office including China National Intellectual Property Administration, China (which can claim the priority of the invention or utility model filed earlier). Then, within 30 months from the date of international application (if there is priority, from the earliest priority date), submit an application to JPO for entering the national phase of Japan. It should be noted that in order to enter the national phase through PCT application in Japan, the declaration of entering the national phase, that is, the domestic written statement, must be submitted within 30 months from the application date (priority date) and the corresponding fees must be paid. 2. Applying for a Japanese patent through the Paris Convention means that after the applicant filed a national patent application in any member country of the Paris Convention for the first time, he filed a patent application for the same theme with JPO within 12 months (invention or utility model) or 6 months (design) and claimed priority. 3. Submit a patent application directly to JPO. The applicant can directly submit a patent application to JPO, but it should be noted that when an invention or utility model completed in China applies for a patent overseas, it needs to be subject to confidentiality review in China in advance. Otherwise, the China patent application corresponding to the patent application will not be granted the patent right (Article 20 of the Franchise Law).
