3. Exclusive license, also known as exclusive license, means that the licensor will not sign a license contract with a third party for the patented technology except allowing the licensee to use the patented technology within the specified period and area, but the licensor still has the right to use the patented technology.
4. Sub-licensing means that the licensee can allow a third party to use the patent in whole or in part in addition to using the patented technology in a certain period and within a certain geographical scope. Compared with the original license, it is called sub-license. Unless it is clearly stipulated in the original license contract, the licensee has no right to exercise the sub-license right. When sublicensing, the original licensor has the right to share the benefits obtained by the licensee in sublicensing.
5. Cross-licensing means that the two patents before and after are technically dependent, and the obligee confirms each other's right to use through the contract. Therefore, this license is more common between the patentee of the original patent and the patentee of the subordinate patent.
