Can invention patents be sold?

I can't. 1. Although the right to apply for a patent and the patent right do not belong to the inventor or designer, this Law still gives the inventor or designer the right to sign the patent document, so as to show that he has made substantial contributions to the invention and creation, affirm the intellectual labor achievements of the inventor or designer, and stimulate the inventor or designer's enthusiasm for invention and creation. At the same time, the entity granted the patent right will determine when to implement the provisions of Article 16 of the Patent Law. 2. The right of authorship is the right given to the inventor or designer by law, and the inventor or designer may or may not exercise it. Just because an inventor or designer has not signed a patent document, he cannot be considered as an inventor or designer of an invention-creation.
