Patents are helpful to the evaluation of professional titles, but there are more opportunities to use patents when evaluating the professional titles of middle and senior engineers. Patent is a way to add points to the evaluation conditions of professional titles. If you have the opportunity to participate in the patent title evaluation, it will be helpful for your title promotion, so don't underestimate the role of patents. As far as the position of patent author is concerned, only the top four inventors of the patent can add points to the title.
