Patent System in Japan

At the 3rd Japan-India Intellectual Property Evaluation Meeting, the Japan Patent Office (JPO) and the Ministry of Commerce and Industry of India signed the agreement document regarding the start of the Japan-India Patent Prosecution Highway (PPH) trial.

From October 1, 2019, a new mediation procedure called “Intellectual Property Mediation” has started in relation to disputes over intellectual property rights.

“Intellectual Property Mediation” is a mediation committee consisting of judges, lawyers and patent attorneys based on documents submitted by a certain date regarding disputes over intellectual property rights that have arisen in the course of business. This is a judicial service that provides a third dispute resolution tool that has characteristics not found in lawsuits and provisional dispositions. 

The JPO held the 9th Japan-ASEAN Patent Office Directors' Meeting and the ASEAN Patent Office Symposium 2019 in Tokyo on August 6-7, 2019.


The JPO held its first Japan-Africa Patent Office policy dialogue in time for TICAD7 held in Yokohama from August 27 (Tuesday) to 30 (Friday), 2019.


With the remarkable development of AI-related technology in recent years, the JPO has investigated the status of AI-related patent applications in Japan and overseas, assuming that patent applications have increased across technical fields and this trend will continue.
