An Exercise In Restraint: Seeking And Combatting Injunctive Relief

Prior to the Supreme Court's ruling in eBay v. MercExchange, when there was a finding of infringement, granting an injunction was almost automatic. See Richardson v. Suzuki Motor Co., Ltd., 868 F.2d 1226 (Fed. Cir. 1989). But eBay rejected this categorical grant of injunctions, raising the bar for obtaining such relief. The Court's decision in eBay sets forth the test used in United States district courts for establishing the necessity of a permanent injunction.

The four eBay factors represent four high hurdles for patentees to meet for the entry of this exceptional relief and four avenues for alleged infringers to attack such requests. After looking at the contemporary grant rates for injunctive relief, we outline just some of the ways in which patentees can meet these hurdles and ways in which alleged infringers may refine their attacks.
