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

The United States District Court for the Eastern District of Texas, part of the U.S. Court of Appeals for the Fifth Circuit, has re-emerged as the nation's busiest and most influential venue for patent litigation. Historically known as the "patent litigation capital of America," the district saw its dominance diminish after the Supreme Court's 2017 TC Heartland decision, which tightened venue requirements. However, following procedural changes in other popular patent venues, the Eastern District has reclaimed its top position, attracting a significant percentage of all new patent infringement lawsuits filed nationwide. As of early 2026, the district is the leading venue for patent cases overall and for those filed by non-practicing entities (NPEs).

The district maintains a reputation for experienced judges and a pace of litigation that moves cases toward trial efficiently. While often labeled a "rocket docket," recent data suggests an average time-to-trial of approximately 24 to 29 months. The court is known for its detailed and well-established Local Patent Rules, which govern the progression of cases, setting firm deadlines for infringement contentions, invalidity contentions, and the claim construction process. These rules create a structured and predictable schedule, which is often seen as an advantage by litigants. The district's juries are also a significant factor, having returned some of the largest patent damage awards in the country in recent years.

The court's docket features a high volume of cases filed by prolific patent asserters, as seen in recent filings such as IOT Innovations LLC v. Schneider USA Inc, Lepton Computing LLC v. Samsung Electronics America Inc et al., and multiple cases from entities like ContentNexus LLC and Modulus Systems LLC. The district has also hosted significant trials with major technology companies, including a long-running dispute between PanOptis and Apple that resulted in multiple jury verdicts. Rulings from the district's judges often draw national attention; for example, a decision by Judge Mazzant was among the first to apply the Supreme Court's Halo standard for awarding enhanced damages for willful infringement.

Two judges handle a substantial portion of the district's patent docket. Chief Judge Rodney Gilstrap is the most active patent judge in the United States, presiding over a significant percentage of all patent cases filed nationally. His Marshall courthouse is the epicenter of the district's patent activity. Judge Amos L. Mazzant, based in Sherman, also manages a heavy patent caseload and is known for his detailed rulings on discovery and damages. These judges' deep experience with the unique procedures and substantive law of patent litigation contributes to the district's prominence as a preferred venue for patent disputes.
