If someone else's patent A is under trial, I find that patent B is similar to patent A (the same patent), and the applicant of AB is different, and the date of B is earlier than that of A. How should I report it?
I wrote a public opinion, similar to the reply to the notice of examination opinions, explaining the reasons why it should not be authorized around Article 53 of the Detailed Rules. Of course, it is more effective to be specific. I didn't send the final document. The recipient should be in the acceptance office of China National Intellectual Property Administration Patent Office, and the patent application number must be clearly written.
Send it by registered mail to the acceptance office of China National Intellectual Property Administration Patent Office (No.6, West Tucheng Road, Jimenqiao, Haidian District, Beijing), and indicate the public opinion on the envelope.
