Why do patent rights only have property rights and no personal rights?

It is generally considered not to be included. Because personal rights refer to identity rights and personality rights. Personality right is a human right (life, health, privacy, name, portrait), and identity right is the right to maintain a certain identity (honor right-world champion, spouse right-marital status).

Patent right is the exclusive right enjoyed by the inventor or designer for invention and creation within the time limit prescribed by law. It is not a patent right to mark one's name in a patent, and one cannot have the right to say that one is an inventor or patentee. ?

Patent right is a kind of property right and an intangible property right; In a broad sense, the inventor's right of signature can be regarded as a personal right in the patent right, but the relevant laws do not provide substantial protection for the inventor's right of signature.
