The right of signature is an important personal right of the inventor or designer. By exercising the right of signature, the society can know who is the inventor and designer of the invention, which embodies the affirmation and respect for the intellectual labor achievements of the inventor or designer. For service invention-creation, although the patent application right and 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-creation, affirm the intellectual labor achievements of the inventor or designer, stimulate the inventor or designer's enthusiasm for invention-creation, and at the same time, it is also the basis for the unit granted patent right to determine the objects of reward and remuneration when implementing the provisions of Article 16 of the Patent Law. The right of signature is a kind of spiritual right, which belongs to the personal right. Compared with other rights, it has the following characteristics: 1, exclusive, that is, the right of signature can only be enjoyed by the inventor or designer, and no one else can enjoy it; 2. Inaccessibility, that is, the right to sign is inseparable from the inventor or designer himself, and has nothing to do with the change of ownership of patent application right and patent right. Even if the patent application right and patent right are transferred, the transferee does not have the right to sign. On the other hand, the right to sign cannot be inherited. Two, the right of signature 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.
