What is the basis of patent certification?

What is the basis of patent certification? Before there is a clear patent law, it can be said that there is no patent application, but even if there is a corresponding patent law, there are not necessarily many patentees applying for patents; The reason is that the patentee lacks awareness of legal protection and thinks that it costs money to apply for a patent. I invented the patent and I have the final say. This is not the same as a patent certificate. What the legal society needs now is a patent certificate or a copy of the patent. What is the basis of patent certificate in the related article "Application Process of Invention Patent"? Patent certificate is actually a patent certificate; This is a document that proves that China National Intellectual Property Administration has issued a patent certificate. The conditions of the request are proved by the patent certificate and only issued to the patentee. China National Intellectual Property Administration will no longer issue patent certificates for patents that are in late payment period, recovery period or have been terminated. Patent certificate refers to the certificate issued by the patent administration department of the State Council that the patent application has passed the examination and found no reason for rejection, and meets the conditions for granting patent right. Because of the duration of the patent right, the patent certificate has the same certification period; The authorization process of invention patent is relatively long, generally from the submission of application, one or two years to at least half a year, before authorization can be obtained, so as to obtain the invention patent certificate. The term of invention patent right is 20 years, the term of utility model patent right is 10 year from the date of application, and the term of design patent right is 10 year from the date of application. Finally, some patentees may ask, can all patentees get certificates? Patent certificates may not be available to everyone, including the patentee. Why do you say that? Because there is usually only one patent certificate, maybe only one person can get it. What about other patentees? No certificate? No, in addition to the patent certificate, there is also a copy of the patent certificate, and every patentee can apply. It is also a patent certificate with the same legal effect.
