Part of the patent case before prosecution is invalid.

According to relevant information, after the patent is invalid, it will not be prosecuted for unfair competition. After the patent is invalidated, the product or technology involved in the patent is legally used by others, but it does not mean that the holder of the invalid patent will be sued for unfair competition. Because the invalidation of a patent means that the patent is no longer protected by law, the holder of an invalid patent can no longer sue others for infringement of its patent right on the basis of the patent. Unfair competition mainly refers to the act of obtaining commercial interests or harming the commercial interests of others through unfair means in commercial activities. If others use invalid patented technology or products without violating relevant laws and regulations, and there are no other improper means or behaviors, the right holder of invalid patents usually cannot sue others for unfair competition.
