How to improve patent stability?

(1) Search for patents: Before applying for a patent, search for relevant information of the patent to avoid infringement. (2) Respond to the invalid request seriously: the patentee should read and understand the relevant technology carefully, understand the reasons for invalidation, put forward rebuttal opinions, prepare a defense, and request the Patent Office to reject the invalid request. (3) Principal-agent: Some enterprises and universities will entrust patents to professional intellectual property agencies for maintenance, so as to ensure the validity of patents and the settlement of disputes. (4) Mastering the core technology: Mastering the core technology is the foundation of an enterprise, so improving the research and development of patents and improving the quality of patents are the key points that can really avoid patent invalidation and disputes.
