A: Whether the applied patent can be sold is not the only criterion for judging whether to compensate. The purpose of most patent applicants is not to sell, but to protect their own product market, so there is no compensation for applying for a patent. In addition, the essence of patent protection can be understood through patent application, and the risk of patent infringement can be avoided through patent application and patent analysis, and there is no compensation problem.
If the sole purpose of applying for a patent is to sell, then the official fee and agency fee paid for applying for a patent will not be recovered, which is a loss.
