This industry needs precipitation as much as lawyers.
Moreover, it is not the people who write patents who have more money, but the people who pull customers have more money. Write a case, almost 5K a month.
Graduate students must have written patents in the past.
Of course there is development. Getting a patent agent within three years of working will help your income.
This industry has been mixed up for a long time, and I want to be the head of intellectual property in a large enterprise with an annual salary of 50W. However, not everyone can do this. In addition to analyzing the technological development of an industry, you also need to experience how your technology is done, how it is laid out, how it bypasses other people's technology and so on.
To sum up, it is not recommended to go to the patent office. Do your major, have technology accumulation, product accumulation, want to engage in patents, you can jump.
