If a patent has an effective foreign licensing contract, these effective foreign licensing contracts will have a positive or negative impact on the value of patent assets, and option C is incorrect. If the content of patent claims makes the scope of rights protection wide and there are no unnecessary technical features, obtaining evidence for infringing products will increase the value of patents, and option D is incorrect.
