This paper deals with the widely-known technology plea in the patent infringement litigation in terms of its concept, its scope of application, the principles of judgement, and the problems of freedom. It proposes that the technology against the patent infringement is supposed to be a kind of widely-known technology, but it should not be free. The widely-known technology pleas could be applied to all sorts of patents, including the realm of the same or similar infringement. This kind of technology could be both independent and component.The widely-known technology plea, in effect, belongs to a process of virtually invalid patent. This modei promotes the judgement of the patent infringement, guards against the abuse of patents, and protects the rights and interests of the public.
