E.D. Tex. (Tyler Div.)

I'll research the current state of this district's patent practice before writing.

Useful baseline. Now let me verify transfer practice, judges, and the tracked cases.

Now let me verify judges, division assignments, and recent rule changes.

Court Profile — U.S. District Court for the Eastern District of Texas (Tyler Division)

Court overview. The U.S. District Court for the Eastern District of Texas sits in the Fifth Circuit and is divided into divisions including Tyler, Marshall, Texarkana, Beaumont and Lufkin. Patent cases in the district are not evenly distributed: Tyler is one of the two divisions (with Marshall) that carries the bulk of the patent docket, and cases filed in Tyler are frequently handled by the Marshall-based district judge assigned to the case. The district has eight authorized judgeships with no vacant-judgeship months in the most recent AOUSC Judicial Caseload Profile. After several years of reduced activity following TC Heartland (2017), EDTX reclaimed the top national patent venue: Lex Machina's 2025 report found it led all districts in new patent filings in both 2023 and 2024, and its 2026 report pegged EDTX at roughly a quarter of all U.S. patent suits in 2025 (about 1,245–1,248 cases, depending on the published count), ahead of the Western District of Texas and the District of Delaware combined.

Patent docket reputation. EDTX earned the "rocket docket" label in the 2000s and 2010s for fast schedules and high plaintiff win rates, and remains the most plaintiff-chosen venue. That reputation is now partly dated on speed. The AOUSC caseload profile for the district shows median civil filing-to-trial time rising from 18.0 months (FY2019) to about 24.5 months in the most recent reported year; PTAB petitioners have cited a median of 25.9 months for the 12 months ending March 31, 2025. Trial calendars are crowded — filings in Gilstrap cases show many patent trials stacked in the same weeks — and practitioners quoted in Bloomberg Law (April 2026) describe growing uncertainty in actually getting cases tried on the scheduled date. On transfer practice, post-TC Heartland data showed grant rates for transfer/dismissal motions out of EDTX rising sharply (from roughly 40% pre-decision to about 84% in the 90 days after, per a widely cited analysis); recent district-specific grant rates for 2024–2025 were not verified in this research. Claim construction is conducted under the local patent rules with a dedicated Markman hearing; the district's patent docket runs predominantly on jury trials, though bench trials occur (for example, post-trial findings on prosecution laches and equitable defenses). Published commentary in 2025–2026 (including quotes in Bloomberg Law) reports that defendant success rates in EDTX have risen, so the traditional "plaintiff-friendly" characterization should be treated cautiously.

Local rules and procedures. EDTX's Local Patent Rules, first adopted in Marshall in 2001 under Judge T. John Ward and extended district-wide in 2005, are the template emulated by other districts. Key steps: P.R. 3-1/3-2 infringement contentions and accompanying production (due 10 days before the initial case management conference); P.R. 3-3/3-4 invalidity contentions (45 days after infringement contentions); P.R. 4-1 exchange of terms for construction (10 days after invalidity contentions); P.R. 4-2 preliminary constructions and extrinsic evidence (20 days after 4-1); P.R. 4-3 joint claim construction and prehearing statement (60 days after invalidity contentions); P.R. 4-4 claim construction discovery (30 days after 4-3); P.R. 4-5 briefs (opening 45 days after 4-3, response 14 days, reply 7 days); and P.R. 4-6 hearing set roughly two weeks after the reply, subject to the court's calendar. The district has modified these rules twice in important respects: deadlines are keyed off the scheduled claim construction hearing date (e.g., P.R. 4-1 due 140 days before the hearing) to avoid briefing that outruns the court's calendar, and P.R. 3-1(g)/3-3(e) address software limitations and source code production. Individual judges add significant requirements via the district's model docket control and discovery orders: early claim and prior-art limits (commonly capped at five claims per patent and a total across patents), page and hard-copy rules for dispositive and Daubert briefing, a required joint notice on mediation within 14 days of the claim construction order, limits on attachments to discovery motions (five pages under the "meet and confer" standing order), and — in Judge Gilstrap's court — a Standing Order Regarding Subject-Matter Eligibility Contentions requiring § 101 contentions on roughly the invalidity-contention timetable.

Notable cases. The two tracked matters are both NPE suits by Realtime Adaptive Streaming LLC, a Tyler-based entity asserting data-compression patents (H.264/H.265-related): Realtime Adaptive Streaming LLC v. Amazon.com, Inc., No. 6:17-cv-00549 (E.D. Tex., Tyler Div., filed Sept. 27, 2017) and Realtime Adaptive Streaming LLC v. Samsung Electronics Co., Ltd. et al., No. 6:18-cv-00113 (E.D. Tex., Tyler Div., filed Mar. 9, 2018). Both were assigned to Judge Gilstrap with Magistrate Judge Roy S. Payne; the Amazon case proceeded through venue and TC Heartland–era motions, a mediation referral, and a 2019 trial setting, and both drew parallel IPR petitions (e.g., IPR2018-01187 by Hulu, Amazon and Netflix). Related Realtime actions were the subject of In re: Realtime Adaptive Streaming LLC Patent Litigation, MDL No. 2845, in which the JPML declined centralization (2018). More broadly, EDTX has produced some of the largest recent patent verdicts, and the district has been a frequent venue for standard-essential-patent and wireless disputes (e.g., Optis v. Apple) and for large Marshall jury awards; several of the biggest 2024–2025 verdicts nationally were rendered elsewhere, so the district's share of headline damages awards should not be overstated.

Judges. Judge James Rodney Gilstrap (Marshall) is by far the most prominent patent judge in the district and one of the most active in the country — reported at roughly 1,018–1,029 new patent cases in 2025 alone, and close to 20% of all U.S. patent cases over the most recent three-year window; both tracked Realtime cases were assigned to him. Chief Judge Amos L. Mazzant III (Sherman) has spoken publicly about EDTX patent volume, time-to-trial, litigation-funding disclosure and § 101 reform (IAM, April 2025). Magistrate Judge Roy S. Payne (Marshall) handles a substantial share of claim construction hearings and pretrial management, including in the tracked Realtime matters. Judge Robert W. Schroeder III (Texarkana) also sits on the district's patent docket (not independently re-verified in this research). Statistically supported plaintiff/defendant leanings for individual EDTX judges were not confirmed from Lex Machina, Unified Patents or Reuters in this review; the commonly cited "plaintiff-friendly" framing rests largely on older qualitative reporting and should be cited with care.
