A Practice Note discussing patent infringement claims and defenses in the US federal courts. Patent infringement occurs when someone makes, uses, sells, offers to sell, or imports into the US a patented invention without the patent owner's permission. In most cases the typical recipe for a "killer Margarita" or "the best barbeque sauce ever" will not be patentable because they won't be unique enough. A patent owner can enforce its patent rights against an infringer in any federal district court that has personal jurisdiction over the defendant. Section 271(f)(1) also requires that the defendant "actively induce" an infringing combination outside of the United States. Federal Court Interpreters Interpreters ensure that justice is carried out fairly for defendants and other stakeholders. Under Section 286, the patent owner has six years to file their infringement action after the infringement occurs.
