The European Patent Office (EPO) and the China National Intellectual Property Administration (CNIPA) agreed to the extension of the pilot on 22 September. Since its launch in December 2020, more than 770 enterprises, universities, and research institutes in China have designated the EPO as their International Searching Authority, benefiting from fast, top-quality search reports and insightful written opinions. The pilot continues to accept up to 3000 applications per year, maintaining broad access to its benefits, and the applications must be filed in English.

By choosing the EPO as their ISA, Chinese nationals and residents gain a strategic advantage.

1. They can accelerate the European patent grant process when entering the European phase and bypass supplementary search, thereby saving substantial time and cost

2. Additionally, these applicants benefit from a 75% reduction in examination fees when requesting international preliminary examination under PCT Chapter II with the EPO.

EPO noted that by simplifying procedures, reducing costs, and delivering tangible results to innovators, it exemplifies the impact of strategic international cooperation. This extension is more than a signal of commitment between the EPO and the CNIPA, it is a direct endorsement of the shared mission to elevate innovation, reduce barriers, and strengthen cooperation across regions.

According to CNIPA, as an important part of the cooperation between the CNIPA and the EPO, the pilot project has been widely welcomed by Chinese users since it was launched. The extension of the project enables Chinese entities to continue to choose the EPO as ISA and thus making it easier to apply for IP and get patent protection in Europe.
