A spokesman for the Ministry of Commerce stated on November 18 that China has noticed that the United States has recently revised the rules related to invalidation of patent applications in the name of "national security." China believes that the US approach violates its international obligations related to intellectual property rights and is a discriminatory restriction on the legitimate rights of Chinese companies. China will pay close attention to the development of the situation and take necessary measures to resolutely safeguard the legitimate rights and interests of Chinese enterprises.

A reporter asked that the U.S. Patent and Trademark Office of the Department of Commerce recently issued a memorandum to modify the transparency rules for patent invalidation applications, focusing on reviewing applications submitted by companies with foreign backgrounds. It is reported that individual Chinese companies have received notices from the United States requiring them to state the reasons for applying for patent invalidation. What is the Ministry of Commerce’s comment on this? The spokesperson of the Ministry of Commerce made the above response.
