Can further inventions and creations based on other people's patented technology apply for patents? If yes, how to apply? How to deal with the original patentee

1. According to the provisions of the Patent Law, as long as your technical scheme is innovative and practical on the basis of previous patents, you can apply for a patent: for example, a chair based on a stool can also be patented (compared with a stool, it has an extra backrest function).

2. Patent application: Write your technical proposal as a patent application document and submit it to China National Intellectual Property Administration for acceptance together with other relevant materials.

3. How to deal with the relationship with the original patentee: If your patent is authorized, there is no doubt that the products you produce according to this patent infringe the patent right of the previous patent. If your patented technology is promising and your products can occupy the market, then you can cross-license and restrict each other.
