eBay Inc. v. MercExchange, L. L. C., 547 U.S. 388 (2006)
Primary Holding
A federal court considering whether to award permanent injunctive relief in patent infringement cases must apply the traditional four-factor test used in equity, which requires the plaintiff to demonstrate irreparable injury, inadequacy of legal remedies, a balance of hardships favoring the plaintiff, and that the public interest would not be disserved by the injunction.
In the case of eBay Inc. v. MercExchange, the Supreme Court decided that when a company wants to stop another company from using its patented idea, it must show that it has suffered serious harm and that money alone won't fix the problem. This ruling is important for consumers because it ensures that patent holders can't easily shut down competitors without proving they really need that protection. This case is relevant if someone is involved in a dispute over a patent, as it sets the rules for when a court can issue an order to stop someone from using a patented invention.

In the case of eBay Inc. v. MercExchange, L.L.C., the underlying dispute arose when MercExchange, a company holding several patents, including a business method patent for an electronic marketplace, sought to license its patent to eBay and its subsidiary Half.com. After negotiations failed, MercExchange filed a patent infringement lawsuit against eBay and Half.com in the United States District Court for the Eastern District of Virginia. A jury found that the patent was valid and that eBay and Half.com had infringed it, determining that damages were warranted. Following the jury's verdict, MercExchange requested a permanent injunction to prevent eBay and Half.com from continuing their infringing activities. However, the District Court denied this motion for injunctive relief. The Court of Appeals for the Federal Circuit subsequently reversed this decision, applying a general rule that permanent injunctions should be issued in patent infringement cases unless exceptional circumstances exist. This led to eBay petitioning for certiorari, prompting the Supreme Court to review the appropriateness of the Federal Circuit's general rule regarding permanent injunctions in patent cases. The Supreme Court's opinion emphasized that the traditional four-factor test for granting permanent injunctions, which includes considerations of irreparable injury and the inadequacy of legal remedies, applies equally to patent disputes. The Court noted that the Patent Act allows for injunctions "in accordance with the principles of equity," indicating that a departure from established equitable practices should not be assumed without clear congressional intent. This case ultimately clarified the standards for issuing permanent injunctions in the context of patent law.
Whether a federal court, when considering a request for permanent injunctive relief in a patent infringement case, must apply the traditional four-factor test used in equity, rather than a general rule favoring the issuance of such injunctions absent exceptional circumstances.
The judgment is reversed.
