Comparative Study on Trial and Appeal Practices among JPO, KIPO and SIPO

June 2017

Japan Patent Office
Trial and Appeal Department

The first Joint Experts Group of Trial and Appeal (JEGTA) was held in 2013 in order to promote cooperation, advance the exchange of information and analyses relating to the systems/practice, deepen their mutual understanding, etc. among the JPO, the KIPO and the SIPO (the Three Offices) in the field of trials and appeals. The Three Offices have ever since conducted comparative studies on the trial and appeal systems/practice in each of the three countries so that users are able to have a deep understanding of their trial and appeal systems.

The JPO, the KIPO and the SIPO have published a new report titled “Comparative Study on the Patent Trial for Invalidation among JPO, KIPO and SIPO.” The report is available on this website (See below).

It is the hope of the Three Offices that these reports will help you gain a better understanding of different views concerning the trial and appeal practice at the Three Offices.
