The specific process of patent transfer includes the following three aspects:
First, before the patent is transferred, the assignee should verify the legal status of the transferred patent, such as whether there are multiple patentees, whether the patent status is valid or invalid, whether the patent is pledged, etc.
Second, when signing a written patent transfer contract, it is necessary to clarify the way of patent transfer, the transfer price and the effective time of the contract.
Third, the patent transfer should be registered and take effect, so after signing the patent transfer contract, it should be announced to the patent administration department of the Intellectual Property Office after filing and registration.
Legal basis: Article 10 of the Patent Law of People's Republic of China (PRC), the patent application right and patent right can be transferred. Where a unit or individual in China transfers the right to apply for a patent or the patent right to a foreigner, foreign enterprise or other foreign organization, it shall go through the formalities in accordance with the provisions of relevant laws and administrative regulations.

The transfer of the right to apply for a patent or the patent right shall take effect from the date of registration.
