Which is more developed, patent agent assistant or drug research and development?

Each has its advantages and disadvantages. Personally, I think that drug research and development may be slow and will be exposed to toxic and harmful drugs; But maybe the starting income will be better. Compared with drug research and development, patent assistant may start with less income, work harder and have better work experience. In addition, the development of patent agents in Beishangguang is more promising. For reference only.
