This concerns Innova's appeal of a district court's preliminary injunction favoring Power Probe in a patent infringement lawsuit. Power Probe sued Innova for allegedly infringing its patent on an electrical test device. The district court initially denied the injunction but was reversed on appeal regarding claim construction. Subsequently, the district court granted a preliminary injunction, finding Power Probe likely to succeed on the merits and suffer irreparable harm. The Federal Circuit reviewed the district court's decision based on four factors for preliminary injunctions and the Ninth Circuit's abuse of discretion standard. Ultimately, the Federal Circuit affirmed the district court's grant of the preliminary injunction, finding no abuse of discretion in its analysis of the relevant factors.
