Is the invention patent double checked?

Legal analysis: double check. When an inventor applies for a patent, he usually has to go through at least two duplicate checking processes. The first time is before the application, in order to improve the invention content and improve the probability of successful application, the second time is in the patent office, where the staff who review the patent content will check the invention for authorization.

Legal basis: the design granted the patent right in Article 23 of the Patent Law of People's Republic of China (PRC) does not belong to the existing design; Before the filing date, no unit or individual has filed an application with the patent administration department of the State Council for the same design, and it is recorded in the patent documents published after the filing date. Compared with the existing design or the combination of existing design features, the patented design should have obvious differences. A design that has been granted a patent right shall not conflict with the legal rights that others have obtained before the date of application. Existing designs as mentioned in this Law refer to designs known to the public at home and abroad before the date of application.
