Remedies



The Patent Act provides for several remedies in the event of an infringement, including injunctive relief, compensable damages, treble damages when appropriate to punish the infringer, payment of attorneys' fees in cases involving knowing infringement, and payment of the costs incurred in bringing the infringement claim in court.



The owner of a patent has a right of action for the unlawful invasion of patent rights by an infringement that has arisen within six years from the date when the lawsuit is initiated.

Injunction Courts frequently grant injunctions to protect property rights in patents. An INJUNCTION is a court decree that orders an infringer to stop illegally making, using, or selling the patented article. An injunction is only granted when an award of monetary damages will not adequately remedy the situation—for example, when an infringer plans to continue the unlawful acts. If an individual disobeys an injunction and continues to make use of an invention without permission, he will be guilty of CONTEMPT and subject to a fine or imprisonment or both.

Damages In an action for infringement of a patent, compensation for prior infringements can be awarded; however, compensation will be denied for use of the invention before the date the patent was issued. Where there is an infringement, the court will award the patentee actual damages adequate to compensate for the loss in an amount that is equal to a reasonable royalty for the infringing use, together with interest or costs set by the court. If the jury in a trial does not determine the amount of damages, the court will. In either case, the court, under the authority of statute, can increase the damages awarded by the jury up to three times the amount determined, called treble damages. Treble damages are punitive and awarded only in certain instances, such as when the infringer intentionally, in bad faith, infringed the patent.

The question of whether amendments to a patent can bar an infringement claim was ruled on by the Supreme Court in the 2002 case of Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., Ltd., 535 U.S. 722, 122 S.Ct. 1831, 152 L.Ed.2d 944 (2002). In that case, the Court unanimously ruled that a patent amendment is not an absolute bar to a claim of infringement under the doctrine of equivalents. Justice ANTHONY KENNEDY, writing for the court, stated the patentee has the burden of proving that the amendment did not surrender the particular equivalent in question.
