As a graduate student, you don't need to do anything outside the subject to apply for a patent.

Of course, our subject direction cannot be directly used to apply for a patent, because the subject direction is the problem I want to solve, not our solution to the problem, and the core content of patent application is precisely the solution to a certain problem we put forward.

So what is the solution to this problem?
