The Ministry of Commerce responded to the US modification of rules related to patent invalidation applications.

On November 18, the spokesperson for the Ministry of Commerce stated that China has noted that the US has recently revised the rules regarding patent invalidation applications in the name of "national security." China believes that the US practice violates its international obligations related to intellectual property rights and is a discriminatory restriction on the legitimate rights of Chinese enterprises. China will closely monitor the development of the situation and take necessary measures to firmly safeguard the legitimate rights and interests of Chinese enterprises. A reporter asked that the US Patent and Trademark Office of the Department of Commerce recently issued a memorandum to revise the transparency rules for patent invalidation applications, with a focus on reviewing applications filed by enterprises with foreign backgrounds. It is reported that individual Chinese enterprises have received notices from the US side, requiring them to state the reasons for applying for patent invalidation. What is the Ministry of Commerce's comment on this? The spokesperson for the Ministry of Commerce made the above response.
