Any unit or individual can use it for free, thus obtaining economic benefits. Invalid patent does not mean that patent is useless. On the contrary, an invalid patent usually means that the patent is not protected by law, and the use of the patent will not infringe the patent rights of others. So after the patent expires, you can get the invalid patent in various ways and keep it for yourself. Many invalid patents actually hide a lot of economic benefits. 2. Any unit or individual can improve invalid patents and implement them free of charge. It is necessary for the patentee of the original invention and the patentee of the improved invention to reach an agreement, because the innovator is an improvement on the basis of the original invention, and in the process of implementation (including self-implementation and technology transfer), the innovator must pay a certain patent technology use fee to the original inventor. However, for an invalid patent, since the original patentee no longer owns the patent right of the patent, the invalid patent can be used and modified for free.
