Why should the patent right be given up?

1. patentee's own interests: during the patent term, the patentee may find that the patented technology has no commercial value or cannot be effectively developed commercially. Giving up the patent right at this time can avoid unnecessary costs and risks.

2. Technological development and market changes: With the continuous development of technology and market changes, the original patented technology may be outdated or replaced by new technologies. Giving up the patent right at this time can avoid unnecessary expenses and maintenance costs.
