S.D.N.Y.

I'll verify the S.D.N.Y.'s patent practice with targeted searches before writing.

Good data on local patent rules and the tracked cases' judges. Now the docket size, transfer practice, and recent rulings.

S.D.N.Y. — Patent Litigation Profile

Court overview. The U.S. District Court for the Southern District of New York sits in the Second Circuit, with its principal patent dockets in Manhattan (Daniel Patrick Moynihan and Thurgood Marshall courthouses) and a White Plains division. Patent appeals go to the U.S. Court of Appeals for the Federal Circuit under 28 U.S.C. § 1295(a)(1). S.D.N.Y. is one of the largest federal districts by overall civil filings, but patent cases are a small slice of its docket, which is dominated by copyright, trademark, securities, and other commercial work; it has never ranked among the top patent venues (E.D. Tex., W.D. Tex., D. Del., N.D. Cal., D.N.J., C.D. Cal.). Historically it was a meaningful secondary venue — Lex Machina's 2013 report ranked S.D.N.Y. third among districts in patent trials (17 trials, over 13% of the national total) and third historically in ANDA/Hatch-Waxman filings (148 cases from 2009 to September 2014, behind D. Del.'s 678 and D.N.J.'s 481). Lex Machina later reported a steep ANDA decline (down to a single case across five quarters by 2017) while design-patent filings rose sharply in the mid-2010s. I could not retrieve a verified current-year S.D.N.Y. patent filing count; exact figures should be pulled from Lex Machina, Unified Patents, or RPX rather than estimated.

Patent docket reputation. S.D.N.Y. is not a "rocket docket." It has no accelerated case-management track for patent cases, no district-wide first-claim-construction deadline tightening (the local rules set default intervals but the court sets its own schedule), and no reputation — in the published analytics I could verify — for the short time-to-trial that characterizes E.D. Tex. or W.D. Tex. Published district-level transfer-grant rates and time-to-trial medians for S.D.N.Y. patent cases were not available to me in verifiable form; I am not supplying numbers I cannot source. Structurally, the venue produces a high volume of early resolutions: the tracked CommWorks campaign resolved by consent judgment/dismissal with prejudice rather than trial. Venue/transfer practice follows the Second Circuit's § 1404(a) framework with no local rule compelling early transfer briefing; there is no specialized patent bench. On trials, Lex Machina's 2013 data for S.D.N.Y. recorded a mix of bench and jury patent trials — a reminder that bench trials are not unusual here, unlike the jury-heavy Texas venues.

Local rules and procedures. S.D.N.Y. does have Local Patent Rules, effective April 8, 2013, adopted jointly with E.D.N.Y. They are deliberately thin — roughly three pages — compared with the E.D. Tex. or N.D. Cal. patent rules, and apply to infringement, validity, and unenforceability actions (L. Pat. R. 1). Key mechanics: infringement contentions within 45 days of the scheduling conference; invalidity contentions within 45 days of infringement contentions; a Joint Disputed Claim Terms Chart (L. Pat. R. 11); and claim-construction briefing on fixed intervals — opening brief 30 days after the chart, response 30 days later, reply 7 days after the response (L. Pat. R. 12). Case management is otherwise driven by individual judges' practices, and S.D.N.Y. judges routinely require pre-motion letters/conferences (the CommWorks dockets show joint pre-scheduling conference letters) and frequently issue text-only orders. Related-case consolidation under Local Civil Rule 13 matters in multi-defendant campaigns — in CommWorks, the RCN case was referred to Judge Schofield as possibly related to the Mediacom case. Docket entries in the CommWorks matters also carry a "Case Eligible for Patent Pilot Program" flag, reflecting S.D.N.Y.'s participation in the 2011 Patent Pilot Program; that program has since sunset.

Notable tracked cases and rulings. Two clusters dominate this site's S.D.N.Y. list. First, Intellectual Ventures I LLC v. Citigroup, Inc. (No. 1:14-cv-04638, filed June 25, 2014, Judge Alvin K. Hellerstein) — an NPE assertion of five patents covering payment-security and cryptographic technology against Citibank, part of a bank-focused campaign that included parallel S.D.N.Y. claims against J.P. Morgan and a Maryland action against Capital One. Judge Hellerstein denied Citi's motion to stay pending the related cases (Dec. 9, 2014), reasoning that Citi had shown only the ordinary burden of litigation and no agreement to be bound by adverse rulings. Second, the CommWorks Solutions campaign against cable/ISP defendants — CommWorks v. Mediacom Communications (No. 1:20-cv-07529, Judge Lorna G. Schofield) and CommWorks v. RCN Telecom Services (No. 1:20-cv-07534, Judge Mary Kay Vyskocil), both filed Sept. 14, 2020, asserting nine patents on broadband provisioning, QoS, packet classification, and Wi-Fi access. CommWorks was identified by Unified Patents as an NPE (subsidiary of Brainbox Innovations/IP Investments Group); the RCN matter ended in a consent judgment/dismissal with prejudice (third-party summaries report termination in March 2023), and Unified's ex parte reexamination request on U.S. Patent 6,832,249 was granted Dec. 23, 2021. Other published S.D.N.Y. patent rulings worth knowing: Holotouch, Inc. v. Microsoft Corp. (No. 17-cv-8717, Judge Hellerstein, May 18, 2018) — the Local Patent Rules do not relax the Twombly/Iqbal pleading standard; Network-1 Technologies v. Google (Judge Paul G. Gardephe, 2019) — supplementation of infringement/invalidity contentions under L. Pat. R. 7 and 9 permitted; and Rovi Guides v. Comcast, where the court (noting a transfer from E.D. Tex.) treated § 101 as required content of invalidity contentions under S.D.N.Y. rules and declined to strike.

Judges. Patent cases are assigned randomly across the district's active judges; there is no permanent patent-only bench. Judges appearing in the tracked matters, or in verified published rulings, include Alvin K. Hellerstein (Intellectual Ventures v. Citigroup; Holotouch v. Microsoft), Lorna G. Schofield (CommWorks v. Mediacom), Mary Kay Vyskocil (CommWorks v. RCN), and Paul G. Gardephe (Network-1 v. Google). Lex Machina's 2013 report placed Sidney H. Stein seventh nationally in merits decisions (11 that year), and S.D.N.Y.'s other historically active patent judges include Jed S. Rakoff, Denise Cote, Lewis A. Kaplan, and P. Kevin Castel — though I did not verify specific patent rulings for each, so I would not characterize any of them as plaintiff- or defendant-leaning without published Lex Machina or Unified Patents analysis.

Data caveat. The tracked-case list supplied for this site contains repeated and untitled entries (the CommWorks matters appear multiple times with conflicting status labels). I have treated them as one campaign against two defendants rather than as distinct filings, and anyone relying on this profile for caseload counts should reconcile the duplicates first.
