by Ryan H. Flax, Esq. (Former) Managing Director, Litigation Consulting A2L Consulting On May 26, 2015, the U.S. Supreme Court released its opinion in Commil USA, LLC v. Cisco Systems, Inc. (575 U.S. ____ (2015)) and it will significantly change patent litigation in the U.S.1 In Commil USA, the Court clarified when indirect patent infringement known as “inducement” occurs and how [not] to escape liability. As a bit of background, a patent can be infringed directly and indirectly. The Patent Act, at 35 U.S.C. § 271, makes it unlawful to make, use, sell, or offer to sell (in the U.S.) a patented thing or process without the patent holder’s permission. Part (a) of this section provides liability for direct infringement, that is, outright doing the thing that infringes a patent. Part (b) governs the first of two indirect infringements, induced infringement, and states “whoever actively induces infringement of a patent shall be liable as an infringer.” This is the focus of the Commil USA case. Part (c) of section 271 deals with the second of the indirect infringements (and interestingly, the one that was first statutorily identified), which is contributory infringement, which makes it an infringement to supply a non-staple, component for use in a patented thing or process.
