It is suggested that the landlord should start with the assistant patent agent, be familiar with the patent law and patent examination guide, obtain the patent agent qualification certificate, and slowly handle the case independently and get the commission. Although he can't get rich, it is no problem to live a well-off life. In fact, many intellectual property agencies like people with R&D experience very much, so that they can fully understand technical documents when writing patent documents and communicate with inventors easily. If the landlord wants to develop in the intellectual property industry, it is beneficial to have R&D experience. But this line is boring, so you need to calm down and write at your desk, and the landlord should be mentally prepared.
I have been engaged in intellectual property related work since graduation. Please call me if you have any questions.
