How much is the patent? Is there an intermediary company? Please help. Thank you.

There are several ways to transform patented technology into industry, among which patent transfer is one, commonly known as "selling patents". The specific operation method is as follows: (1) Direct transfer, that is, after the patentee announces the patent transfer announcement through advertising or media propaganda, it attracts units or individuals interested in purchasing and using the patented technology to contact the patentee directly, and the two parties sign a patent transfer contract, and the buyer pays the patentee the patent fee, which will take effect after notarization by a notary office. (2) Indirect transfer: the patentee registers the patented technology he invented with a technical consulting service organization with legal business qualifications, and the technical consulting service organization issues a patent transfer announcement to the outside world, and the unit or individual who intends to purchase the patent use right indirectly purchases the patent use right through the technical consulting service organization. Then the service organization notarizes and pays the transfer fee to the patentee. At the same time, after receiving the patent transfer fee, the patentee pays a certain intermediary fee to the technical service organization according to the prior agreement.
