“Induced infringement” under patent law means a party may be found liable for patent infringement even if it did not itself infringe a patent claim, if it induced another (the “direct” infringer) to infringe a patent claim. For method claims, patent litigators for many years operated under a body of law that required showing that a direct infringer carried out all steps of the claim, and that the inducer encouraged and enabled the infringement by the direct infringer.
