1. First, read the notice of rejection decision carefully. The examiner will explain the reasons for rejection in the notice of rejection decision. Reading the notice of rejection decision carefully is helpful to understand the examiner's opinions and make corresponding treatment according to these opinions.
2. Secondly, submit a request for reexamination to the Patent Reexamination Board. If you think that the examiner's opinion is unreasonable, you can make a reexamination request to the Patent Reexamination Board within 3 months after receiving the notice of rejection, and pay the formal reexamination fee at the same time. In the reexamination request, why do you think that the examiner's opinion in the rejection decision is incorrect? When submitting the review request, you can also modify the application documents to overcome the existing problems. In other words, if the examiner's opinion is really well-founded, then you can try to get authorization by modifying the application documents.
Finally, after reexamination, if the rejection result remains unchanged, the Patent Reexamination Board can be taken as the defendant to bring a lawsuit to the court.
