Narrative Opinion Summary
In a patent infringement case, Power Survey, LLC seeks a preliminary injunction against L-3 Communications Holdings, Inc. (Narda) and Premier Utility Services, LLC, alleging infringement of its patents for a mobile stray voltage detection system. Power Survey claims irreparable harm, citing market erosion and safety risks posed by the defendants' products, which allegedly infringe Power Survey's patents by failing to detect stray voltage effectively. The court evaluates the likelihood of success on the merits, focusing on claim construction and the definition of 'voltage anomaly,' and leans towards Power Survey's interpretation. Defendants argue that the patents are obvious and question the naming of the inventor but fail to provide sufficient evidence. The court finds a likelihood of success for Power Survey regarding patent validity and infringement. Considering irreparable harm, the balance of equities, and public interest, the court grants the preliminary injunction, emphasizing the safety concerns and market impact. Power Survey's technology is crucial in preventing potential hazards associated with stray voltage, and the injunction aims to protect its market position and public safety.
