Belief in Patent Invalidity is not a Defense
The Commil v. Cisco decision involved the issue of what knowledge is required by a defendant in a claim of induced patent infringement. Briefly, a party can be liable for directly infringing the patent of another, where it utilizes patented matter of another without authorization, or by inducing a third party to infringe a patent of another. Induced infringement often involves situations where a party may simply provide the means to third-parties and their use of those means result in infringement of a patent.
