What's the difference between patent transfer and patent licensing?

1. There are different ways to acquire rights. Patent transfer is generally a way to change the patent right when purchasing a patent, which means that the right holder transfers all the patent rights of his patent to the assignee. Patent licensing is usually achieved by signing a patent licensing contract, which means that the patentee allows the licensee to use the patent in a certain way in a certain area and within a certain period of time.

2. In patent licensing, the licensee can only exploit the patent licensed by the licensor within a certain period of time, in a certain area and in a certain way, and pay a certain fee. The patent ownership is still in the hands of the licensor, and the licensee has only limited right to use it, and the licensor has the right to transfer its patent. Patent transfer is different. The transferor loses all patents and the transferee gains all patents. The assignee becomes the new patentee and has the right to completely control the patent.

3. With different conditions for entry into force, patent licensing can only be achieved through a written contract between the licensor and the licensee, with the relevant clauses in the contract as the main reference conditions for the entry into force of the patent. Patent transfer requires both parties to conclude a contract and must be registered with the relevant patent authorities before it can take effect.
