I would like to ask how the patent was transferred.

Patent transfer requires both parties to sign a patent transfer contract, and then go through the formalities for changing the registered items in China National Intellectual Property Administration.

Procedures for changing the description of the project shall be submitted.

1. Record the project change statement.

2. Pay the recording project change fee within one month from the date of request, 200 yuan.

3. Proof materials (patent right transfer contract): If the patentee requests to change due to the right transfer or gift, it shall submit the transfer or gift contract. The contract is concluded by the unit, which shall be stamped with the official seal of the unit or the special seal for the contract. When concluding a contract, a citizen shall sign or seal it. If there is more than one patentee, all the certification materials that the patentee agrees to transfer or donate shall be submitted.
