Excuse me, I want to apply for a patent for a new technology now, but some of this technology uses other people's patented technology. How to deal with it?

Does not affect the patent application. Your patent is different from his patent protection scope, and his prior patent is regarded as existing technology. Many patents are based on the innovations of others' patents. The progress of technology is unstoppable.

However, when the patent is implemented, it needs the permission of the prior patentee. Otherwise, it is still infringement.

The solution is negotiation. You can license your patent and his patent and bind them together to form a win-win situation.

If the other party maliciously monopolizes and intentionally fails to implement it, it may apply to the State Council for compulsory license when it meets the statutory conditions.
