Trademark agent is a relatively professional position. Some companies with trademark business have this position specifically, which is to help customers apply for trademarks and handle subsequent opposition procedures. This does not require a science or engineering background. A trademark attorney has no role in being a patent attorney.

Patent agents need to understand the client’s technical solutions and require relatively deep knowledge of science and engineering. If you have the confidence, you can give it a try. If it is just a self-study exam, the journey is probably quite long
