1 October 2021


The EPO and CNIPA have launched a user survey on the pilot that enables nationals and residents of the People's Republic of China to select the EPO as their International Search Authority for PCT applications filed in English with CNIPA or the International Bureau of WIPO as receiving Offices. You can submit your comments in Chinese, English, French or German until 15 October 2021.

Whether or not you have already participated in the pilot, we sincerely hope that you will share your input and expectations by taking a few minutes to complete the survey. Your feedback is essential as it helps the EPO and CNIPA continuously improve the services offered to patent applicants.

The pilot was launched on 1 December 2020 and many companies have already benefitted from the scheme via one or multiple applications. A growing number of companies are choosing this route and this agreement further helps Chinese inventors protect their inventions abroad and obtain quicker protection for their inventions in Europe.

Survey replies are anonymous, confidential and personal data is processed in accordance with the Guidelines for the Protection of Personal Data in the EPO.
