Direct acquisition means that one enterprise buys another enterprise's patent, mainly in order to obtain patent ownership. Specific methods can be inquired through the website announcement of the Intellectual Property Office, patent transfer network and other channels. If you or your partner has knowledge, you can communicate and coordinate through the Patent Office or the patent owner, and go directly to China National Intellectual Property Administration for the transfer formalities after confirmation.
When purchasing a patent, it is necessary to determine the type and authorization of the patent to be purchased and find the corresponding seller. Then, it is necessary to stipulate whether the specific right to be transferred is the transfer of the whole patent right or the exclusive license. Finally, you can handle the transfer formalities in China National Intellectual Property Administration by yourself or by entrusting a patent agency.
