I have a personal patent, and I have applied for it. What is the use of patents in universities and schools?

It depends on your school's policies, such as adding credits, subsidies, evaluation bonuses or professional titles, which may also increase your chips for your future work. In addition, the local government may have some policies, such as incentives, subsidies, or extra points for opening accounts in Shanghai and other places. Of course, if your technology is good enough, you can license the transfer. Finally, when applying again, you can consider writing the teacher's name in inventor.
