What if I find someone else has applied for a patent after I invented something?

First, China's patent application system is the first. If someone has applied before you and applied for a patent after the same technical scheme, it is impossible to obtain patent authorization.

Second, if the technical scheme has been made public before the other party's application date, if the other party's patent is authorized, it can make a request for invalidation and revoke the patent accordingly.

Third, if the technical scheme has been used before the other party's application date but not made public, you can continue to use the technology according to the right of first use if the other party's patent is authorized.

In addition, you can also apply for patent protection based on the improvement of this technology.
