As far as you are concerned, it seems to me that it involves the use and transfer of patent rights. Patent transfer can be the transfer of the right to apply for a patent, or the transfer of the right to use a patent (that is, the patent implementation license). Even if the right to use is transferred, it depends on the specific conditions of the contract (scope of use, duration, conditions, etc.). ), so I think you should also look at the relevant contract laws (such as technology transfer contracts, including patent licensing contracts). For reference only, I hope I can help you.
