How to put forward public opinions on invention patents?

Article 48 of the Detailed Rules for the Implementation of China's Patent Law stipulates that from the date of publication of an application for a patent for invention to the date of announcement of the grant of a patent right, anyone can make comments to the patent administration department of the State Council and explain the reasons. To make public comments on a patent, an "opinion statement" shall be filled out, indicating the application number, invention name, applicant and other information, providing reasons and evidence that the patent does not meet the authorization conditions, and the materials shall be delivered to the China National Intellectual Property Administration Patent Office in person or by post.
