In terms of professional title evaluation and professional ability evaluation, only the first and second inventors (or signatories) are considered. Two factors are mainly considered here: First, the substantial contribution to the invention (or scientific and technological achievements) is considered, and the substantial contribution of the first and second inventors (or signatories) is great. Second, considering the current situation, many scientific and technological achievements will be signed by all members of a project team, and even some units will include people who have nothing to do with the project (such as leaders). In fact, they made little contribution.
