Eastern District of Texas
The Eastern District of Texas built the modern playbook for patent litigation. Its Local Patent Rules, Track-style scheduling, and willingness to set firm trial dates made it the country's dominant patent venue from the mid-2000s until the Supreme Court's 2017 decision in TC Heartland reshaped venue. The court remains a major forum, particularly Marshall, where a substantial share of the national docket continues to be tried.
Overview
The U.S. District Court for the Eastern District of Texas covers forty-three counties stretching from the Louisiana border to the suburbs of Dallas. Its patent docket is concentrated in four divisions: Tyler (the seat of court administration), Marshall, Sherman (Plano), and Texarkana. Beaumont and Lufkin host civil work but rarely large patent cases.
The district's prominence in patent litigation grew during the 2000s under judges who set firm trial dates, declined to stay cases for parallel proceedings, and adopted local patent rules that pushed both sides to commit to infringement and invalidity theories early. Filings peaked in the mid-2010s, when the Eastern District at times accounted for a plurality of all patent cases filed in the United States.
Two events shifted that posture. First, the Supreme Court's decision in TC Heartland v. Kraft tightened the meaning of "resides" in 28 U.S.C. § 1400(b), eliminating the prior practice of treating any defendant subject to personal jurisdiction as properly venued for patent purposes. Second, the Federal Circuit issued a series of mandamus opinions sharpening the convenience analysis under § 1404(a) and reining in district courts that, in the appellate panel's view, had under-weighted the location of evidence and willing witnesses outside the venue. The post-2017 caseload reshaped accordingly, with a substantial volume of cases continuing in Marshall but transfer motions becoming a dominant procedural battleground.
As of recent practice, Marshall is the division most commonly associated with high-stakes patent trials, presided over by Judge Rodney Gilstrap, who has handled an outsized share of the district's patent docket. Judge Roy Payne sits as a magistrate judge in Marshall and routinely manages claim construction and discovery in patent cases by referral. Judges in Tyler, Sherman, and Texarkana also carry patent dockets but in smaller numbers.
Local patent rules
The Eastern District's Local Patent Rules (LPR) are among the oldest and most influential in the country, and they served as the model for parallel rules in the Northern District of California and the District of Delaware. The rules impose a sequence of mandatory disclosures that move ahead of formal contention interrogatories.
- LPR 3-1 (Disclosure of Asserted Claims and Infringement Contentions). The patentee must serve, early in the case, an identification of each asserted claim, the accused instrumentality on a claim-by-claim basis, an element-by-element chart, and a statement of which infringement is literal and which under the doctrine of equivalents. The disclosure also requires identification of priority dates and any willfulness theory.
- LPR 3-3 (Invalidity Contentions). The accused infringer must, within a specified period after infringement contentions, identify each item of prior art relied upon, provide claim charts comparing each prior art reference to each asserted claim, identify any § 112 grounds (written description, enablement, definiteness), and identify any § 101 arguments.
- LPR 3-4. Document production accompanying invalidity contentions, including documents sufficient to show the operation of the accused instrumentalities and any prior art documents in the producing party's possession.
- LPR 4-1 to 4-5. The claim construction sequence: exchange of proposed terms, exchange of preliminary constructions and supporting evidence, joint claim construction statement, briefing, and the Markman hearing.
Amendments to contentions require leave on a showing of good cause. The court has historically enforced contention rules strictly, treating late-disclosed theories as waived absent diligence. That stricter posture shapes early case strategy: patentees come in with claim charts already prepared, and accused infringers begin prior art searches before the complaint is even answered.
Typical scheduling
Eastern District scheduling is closer to an event-driven track than a generic civil order. The court's Discovery Order and Docket Control Order, often issued together, specify the LPR sequence and culminate in a firm trial setting roughly eighteen to twenty-four months from the scheduling conference.
A representative sequence runs roughly as follows: infringement contentions a few weeks after the scheduling conference; invalidity contentions about forty-five days after that; exchange of proposed claim terms within a few weeks; claim construction briefing several months later; the Markman hearing; expert reports and depositions; summary judgment and Daubert; pretrial; and trial. The court is known for moving cases on schedule and for rarely continuing trial dates absent extraordinary circumstances.
Trials themselves tend to be tightly time-limited. The court routinely sets per-side hour limits, and counsel are expected to budget opening statements, witness examinations, and closings against that clock. Juries are drawn from the surrounding counties; in Marshall, the venire reflects East Texas demographics, a fact that has historically influenced both jury selection strategy and damages presentation.
Notable practices
Transfer motions
Transfer practice under 28 U.S.C. § 1404(a) has become the central pretrial battleground. The Federal Circuit has issued repeated mandamus opinions reviewing Eastern District transfer denials, including In re Apple Inc., In re Samsung Electronics Co., and the older but still-cited In re Volkswagen of America, Inc., 545 F.3d 304 (5th Cir. 2008) (en banc), which sets the Fifth Circuit framework the district applies. The pattern in many of these decisions is a holding that the district court placed insufficient weight on the location of party witnesses and evidence and too much weight on factors the appellate court treats as marginal. Whether to file the transfer motion early, and how to develop the record on convenience, is now a first-order strategic decision.
Stays pending IPR
Stays pending inter partes review are granted, but less freely than in some other districts. The court weighs simplification, stage of the case, and prejudice, and has frequently denied stays when trial is set within a year. Practitioners track institution decisions closely because timing relative to the case's existing milestones often controls outcome.
Sealing and confidentiality
The court issues a standing protective order template that covers source code, financial information, and other sensitive technical material. Source code review typically occurs at counsel's offices on a non-networked machine subject to printing limits and an inspection log. Sealing of court filings is permitted but disfavored at the merits stage; redaction practice is closely policed at trial.
Recent doctrinal pressure points
Three pressure points dominate current practice. First, the Federal Circuit's mandamus jurisprudence on transfer continues to shape pleading and case-development choices. Plaintiffs assess venue exposure before filing; defendants prepare convenience records as soon as service is effected.
Second, the post-TC Heartland rules around what constitutes a "regular and established place of business" continue to generate disputes, particularly for defendants with employees, retail locations, or warehouse operations in the district. In re Cray Inc., 871 F.3d 1355 (Fed. Cir. 2017), set out the three-part test, but its application is heavily fact-specific.
Third, parallel PTAB proceedings — particularly IPR — interact with the district's trial-setting practice in ways that can produce estoppel consequences before institution decisions are even final. Coordinating between district court and PTAB calendars is now table stakes.
Practical notes for first-time practitioners
- Read the Docket Control Order with the LPRs side by side. The two documents together control the case in a way the Federal Rules alone do not.
- Treat infringement and invalidity contentions as binding. Amendments require diligence. Theories not disclosed under LPR 3-1 or 3-3 risk preclusion.
- Develop your convenience record early. Whether you intend to move to transfer, or to oppose, the location of witnesses and evidence drives the analysis. Affidavits and deposition testimony on these points are the standard form of proof.
- Plan trial-time budgets at the pretrial stage. Per-side hour limits affect witness order, demonstrative strategy, and even claim construction emphasis.
- Coordinate with PTAB counsel. An IPR petition strategy needs to align with the district court trial date. Late-filed petitions are unlikely to support a stay.
- Take local counsel seriously. The court expects active participation by local counsel admitted to the district, and judges have on occasion noted dissatisfaction when local counsel appear in name only.
