How to collect the standard necessary patent license fee?

At present, the patent laws of all countries basically stipulate that the patentee enjoys the patent license right according to law, but there is no provision on the calculation method and payment method of patent license fee. In practice, there are mainly three ways: exclusive license, exclusive license and ordinary license. The patent license fee varies according to factors such as the gold content of the patented technology and the license method. Specific to the determination of a patent technology license fee, it is usually agreed by the licensor and the licensee through the contract. Generally speaking, there are three main payment methods: one-time payment, royalty payment and entry fee plus royalty payment.

Generally speaking, four important factors should be fully considered in the calculation of patent license fees:

1, the factors of the patent itself, such as the innovation degree and industrialization maturity of the patent, the technical field to which it belongs, the type of patent right, the scope of protection, the stability of rights, the difficulty of technical evasion, the effective period, etc. ;

2. Factors related to the content of the license, such as license period, license scope, license mode, etc. ;

3. Relevant factors of the licensee, such as the technical requirements of the licensee, production scale and patent enforcement ability. ;

4. The potential impact of technological development trends in related fields on patent value, because new development trends may indicate that existing patented technologies are about to depreciate or even be eliminated.
