What is the difference between patent exclusive license and patent implementation license contract filing?

A patent exploitation license contract refers to a contract in which the patentee or its authorized person acts as the assignor, allowing the assignee to exploit the patent within the agreed scope, and the assignee pays the agreed royalties. After the contract is established, the transferee may implement the patented technology in the agreed area, time limit and manner. According to the extent and scope of the transferor's transfer of patent use right and the transferee's acquisition of patent use right, the patent exploitation license contract can be divided into the following forms: ① Exclusive patent exploitation license contract. An exclusive license contract for patent exploitation means that the transferee enjoys the right to use the patented technology agreed in the contract within the prescribed scope, and neither the transferor nor any third party may have the right to use the patented technology within the prescribed scope at the same time. (2) Patent exclusive license contract. An exclusive patent license contract means that the transferee enjoys the right to use the patented technology agreed in the contract within the specified scope, and the transferor still retains the right to use it within this scope, but excludes any third party from using the same patented technology within this scope. ③ General patent licensing contract. A general patent licensing contract means that the transferee has the right to use the patented technology within the specified scope, and the transferor not only reserves the right to use the patented technology within this scope, but also reserves the right to transfer the right to use the patented technology to any third party within this scope. The form of license may include granting the transferee a sublicense. The retransfer license shall be a general implementation license.
