专利许可中专利无效的法律问题探析

On Legal Issues Related to Patent Invalidity in Patent License

专利无效时往往涉及停止支付及对已支付许可费的返还的问题,许可协议中"不置疑条款"妨碍了公平竞争原则,是不合理的限制性条款。针对我国被许可人置疑被许可专利有效性时面临的困境,本文指出法律除了否定"不置疑条款"外,还应为被许可人行使"置疑"的权利提供相应的支持。

Suspending licensing fees and returning the amount already paid are normally involved in case of patent invalidity. Non-challenge clause in the license agreement violates the principle of fair competition and falls under the unfairly restrictive provision. With regard to the difficulties Chinese licensees face when challenging the non-challenge clause, this paper points out that the law shall provide relevant support for the licensees in exercising his/her right in addition to invalidating such clause.
