How to evaluate the price of a license to use a patent?

In terms of remuneration, within the framework of a patent exploitation licence, the parties benefit from the greatest freedom.

It is possible to provide for a fixed price and proportional royalties: very often, the contract provides for the payment of a lump sum and the payment of royalties proportional to the exploitation. With regard to these proportional royalties, it is up to the parties to set the rate and the base. It is advisable to base the rate of this royalty on an objective and indisputable element such as the turnover excluding tax or the production of the licensee, for example.

In any event, it is up to you to draw up the appropriate contract.

For more information on your rights, you can contact an industrial property attorney or a lawyer.

Finally, any transfer or modification of the rights attached to a patent must be entered in the national patent register to make the act "enforceable against third parties", i.e. to bring it to the attention of the public so that, on the one hand, he respects its existence and on the other hand that the owner can defend his rights.
