Is there a difference between patent signature first and second?

Legal analysis: 1. When a patent has multiple inventors, the order of signatures is arranged, and the default value is contribution size. Inventors who have made significant contributions have the priority to sign and rank high. As the first inventor of the patent, he has made greater contributions than the second inventor, and the more praise he gets, the higher his status will be.

2. By default, the first inventor of a patent is an external contact. Regarding matters related to patent external communication, the contact information left by the first inventor of the patent will be used, but when patent interests are involved, communication will be made with other inventors. It will not be arranged without the consent of the second inventor.

3. Patents have the function of evaluating professional titles, and the first and second inventors play the role of adding points to professional titles within the scope of professional titles identification. But the questions are different, and the first inventor gets more points. In addition, the title that the first inventor can participate in may not be available to the second inventor.
