宿主细胞、宿主菌株及表达载体的商业授权及商业收费模式讨论

最近国内也加强对细胞株及载体的来源提供证明及授权使用证明。还有如果去国外申报，肯定要事先搞清楚其中的授权及收费模式。
所以想和各位讨论一下这里面涉及到的几个关键词及商业收费模式。
几个关键词：Commercial license、Royalties、annual fees、上市销售提成。例如Life公司的
Freedom® CHO-S® Kit：
“Commercial Licensing that is Simple, Flexible and Without Royalties
Multiple companies provide CHO (Chinese Hamster Ovary) stable cell line development services and products that require annual fees during development of your therapeutic protein. In addition, royalties may be required on the sales of your therapeutic protein upon commercialization. Gibco® Freedom® Kits provide you with the tools that enable you or your CRO provider to develop your stable cell line for just the price of the kit itself. Furthermore, as you move towards commercial use, a flexible license structure is available without the burden of royalties and works to keep it as simple as a onetime payment (Fig 1).

我们最近在联系购买某微生物表达系统(大肠杆菌感受态细胞)，找原研实验室问如果产品上市是否需要谈Commercial license说不用了，因为专利期已过。但不清楚销售该产品（感受态）的公司是否收一些别的费用。就是搞不清楚上述关键词的关系。
