U.S. District Court for the District of Nevada

Patent Litigation Profile: U.S. District Court for the District of Nevada

Court Overview
The United States District Court for the District of Nevada (D. Nev.) is a federal trial court within the jurisdiction of the U.S. Court of Appeals for the Ninth Circuit. The court holds proceedings in Las Vegas and Reno. While not considered one of the nation's top patent venues by case volume, such as the Western District of Texas or the District of Delaware, the District of Nevada has maintained a consistent, moderate patent docket. A 2014 analysis noted a steady increase in patent case filings in the district between 2010 and 2013.

Patent Docket Reputation
The District of Nevada is not known as a "rocket docket" for patent cases. An analysis of federal court data published in 2018 indicated that the average time from filing to trial for civil cases in the district was 43.7 months, one of the slower timelines in the nation at that time. There is no prevailing, data-supported reputation for the court being particularly favorable to either patent holders or accused infringers. The court was a participant in the Patent Pilot Program, a now-sunsetted national program designed to enhance the expertise of judges in patent matters by allowing them to hear more patent cases.

Local Rules and Procedures
The District of Nevada has adopted a specific set of Local Rules of Practice for Patent Cases, which apply to all civil actions involving utility patent infringement or declaratory judgment claims. These rules are designed to structure litigation efficiently by establishing a clear and relatively rigid schedule for discovery and disclosures. Key provisions mandate early and detailed disclosures of infringement and invalidity contentions, as well as a structured process for claim construction briefing and hearings, which helps to crystallize legal theories early in the litigation.

Notable Cases and Judges
The court has handled several significant patent disputes. A notable historical case is Symbol Technologies, Inc. v. Lemelson Medical, Education & Research Foundation, LP, part of the long-running litigation involving the prolific inventor Jerome Lemelson, which was handled by Senior Judge Philip M. Pro. More recently, the district was the original venue for the dispute in Hikma Pharmaceuticals USA Inc. v. Amarin Pharma, Inc., a major "skinny label" case concerning induced infringement that is now before the U.S. Supreme Court as of April 2026. Another tracked case, Datacloud Technologies LLC v. Zillow Group, Inc., was dismissed in 2023.

Several judges in the district have developed experience with patent matters, partly through participation in the former Patent Pilot Program. An analysis of cases filed between 2010 and 2013 showed that Judge Gloria Maria Navarro and Judge Miranda Du had the largest patent caseloads. Along with the now-retired Judge Philip M. Pro, they were the designated Patent Pilot Program judges for the district.
