Abstract:FRAND is a private regulation institution with multi-objectives and balancing many sides interest. It is the essential requirement to take FRAND as a general principle and put private negotiation in good faith as the fundamental mechanism. FRAND commitment is a binding contract commitment, only under special conditions, it may violate antimonopoly law. Therefore, contract law should be given priority in the enforceability of FRAND commitment and take the hybrid enforcement path of “contract law + antimonopoly law”. Private negotiation is the fundamental mechanism to reach a FRAND royalty agreement. Government should not regulate the FRAND royalties. In the case decision, courts should not adhere to a particular methodology on FRAND royalty, and persist on ex ante incremental value benchmark.
