The patent transfer fee depends on how your technology is transferred, that is, it will be clearly reflected in the process of patent transfer. For example, in No.7.com online intellectual property trading platform, the fees mainly include two aspects: patent technology transfer fee = platform service fee+patent trading price (patent price itself)+patent value evaluation fee (optional). If trading on the platform, the third-party platform in 250 yuan mentioned above does not accept the China National Intellectual Property Administration fee.
To sum up, the possible components of intellectual property technology transfer fee are: intellectual property technology transfer price (own price), intellectual property value evaluation fee, agency fee, platform service fee and basic official fee 250 yuan. Its calculation method depends on how you transfer technology!
