N.D.N.Y. (Judge Kahn)

I'll research the court's patent practice before writing.

Court overview

The U.S. District Court for the Northern District of New York (N.D.N.Y.) sits in the Second Circuit and covers 32 upstate counties, with courthouses in Albany, Binghamton, Syracuse, and Utica (Barclay Damon alert on the district's local patent rules). It is a small patent venue by national standards: it has never appeared among the top districts in Lex Machina's annual patent reports, which have consistently been led by W.D. Tex., D. Del., E.D. Tex., and N.D. Cal. (e.g., Lex Machina 2022 report and 2024 report transcript). Justia's docket index for the district lists roughly 178 patent suits cumulatively — an order of magnitude below the annual filings of the leading venues, and consistent with this site tracking only one N.D.N.Y. patent case. I could not verify a published AOUSC/Lex Machina annual figure specific to N.D.N.Y., so treat that count as an index snapshot rather than an official statistic.

Patent docket reputation

There is no well-sourced basis for calling N.D.N.Y. a "rocket docket," and I found no published Lex Machina, Unified Patents, or Reuters analysis characterizing its judges as plaintiff- or defendant-friendly; none should be inferred here. What the docket does show is a pattern common to small, non-preferred venues: high-volume NPE plaintiffs file isolated suits against defendants with upstate New York contacts, and those cases terminate early by settlement, voluntary dismissal, or transfer rather than by adjudication. The tracked case fits that pattern exactly — plaintiff noticed voluntary dismissal the day after filing the complaint and before any answer, and the court granted it about three weeks after filing. Because patent complaints there generally must rest on the defendant's residence or a regular and established place of business in the district, defendants are often regional or local businesses (e.g., Michelin North America v. Techno Pneu, 6:23-cv-01568; Research Products Corp. v. Brilliant Initiatives, 1:24-cv-01436). I could not verify district-specific § 1404 transfer grant rates or median time-to-trial figures for N.D.N.Y.; those numbers, if published, are not well established and the volume is too low for reliable inference.

Local rules and procedures

N.D.N.Y. has its own Local Patent Rules (L. Pat. R. 1–5, cited as "L. Pat. R. ___"), effective January 1, 2012, drafted by an ad hoc committee impaneled by Magistrate Judge David E. Peebles and modeled in part on other districts' rules (district rules PDF; Barclay Damon; Bond Schoeneck & King). Distinctive features: infringement contentions and accompanying document production are due 14 days after the initial Rule 16 conference (L. Pat. R. 3.1–3.2); no more than 10 claim terms may be presented for construction absent leave, with plaintiff and defendant each selecting five if they cannot agree; parties must file a Joint Claim Construction and Prehearing Statement that prioritizes the disputed terms by significance to the case; claim-construction discovery closes 30 days after that statement; and all fact discovery closes 120 days after the claim construction ruling. The rules are drafted to produce full Markman briefing roughly 10–10.5 months after the complaint is filed, somewhat faster than N.D.N.Y.'s counterpart in N.D. Ill. (about 12 months). If the parties do not agree on a protective order, the court enters one by default. Local Civil Rule 1.3 makes the patent rules applicable to all patent actions, and Local Rule 26.2 governs mandatory disclosures.

Notable cases or rulings

• Cedar Lane Technologies Inc. v. Videotec Security, Inc., 8:23-cv-00037 (N.D.N.Y.) — the single case tracked here. Filed Jan. 10, 2023, on patents 6,473,527; 6,972,790; and 8,537,242 (imaging/host-interface technology), assigned to Senior Judge Kahn with referral to Magistrate Judge Daniel J. Stewart. A G.O. 25 filing order set the initial conference for April 10, 2023 in Albany and required the Civil Case Management Plan and mandatory disclosures by April 3, 2023. Plaintiff noticed voluntary dismissal on Jan. 11, 2023 (dismissal by notice under Fed. R. Civ. P. 41(a)(1)(A)(i) is self-executing where no answer or summary-judgment motion has been served), and Judge Kahn granted it without prejudice on Jan. 31, 2023 (docket). Cedar Lane was among the most active patent plaintiffs nationally in that period, with the overwhelming share of its filings in W.D. Tex., D. Del., and E.D. Tex. — N.D.N.Y. was an outlier venue for a single defendant.
• Rensselaer Polytechnic Institute v. Amazon.com, Inc., 1:18-cv-549 (BKS/TWD) — the district's most consequential recent patent dispute. Claim construction was referred to Magistrate Judge Peebles, who held a Markman hearing on April 29, 2021 and issued a Report and Recommendation on Sept. 30, 2021; Judge Brenda K. Sannes adopted it in full on March 18, 2022, including findings on § 112 ¶ 6 / step-plus-function indefiniteness (CourtListener). The case is a useful illustration of the district's practice of delegating claim construction to magistrate judges.
• Vaughan Co. v. Global Bio-Fuels Technology, LLC, 1:12-cv-1292 (DNH/RFT) — Magistrate Judge Randolph F. Treece declined to apply the Local Patent Rules "rigidly or formulaically" where the accused instrumentality was a bid specification rather than a classic product, sustained the contentions, ordered supplementation, and refused to require document inspection outside the district (Justia). It remains the clearest local authority on how strictly L. Pat. R. 3.1 is enforced.

Judges

Patent work in N.D.N.Y. is spread thinly across a small bench, and there is no recognized "patent judge" in the Lex Machina sense.

• Senior Judge Lawrence E. Kahn — the judge in the tracked Cedar Lane case. Appointed by President Clinton (nominated April 18, 1996; commissioned Aug. 1, 1996) and in senior status since Aug. 1, 2007; based in Albany and still taking civil assignments (Wikipedia/Wikiwand).
• Judge Brenda K. Sannes — wrote the adopted claim construction ruling in RPI v. Amazon (2022) and has handled the district's most substantial patent matters in that period.
• Judge Glenn T. Suddaby — described as Chief Judge in 2018 docket text; succeeded Judge Kahn in his seat.
• Judge David N. Hurd and Judge Mae A. D'Agostino — both have handled patent-related dispositive motions and case management; D'Agostino maintains a Case Disposition Pilot in her individual rules. On the magistrate side, David E. Peebles drafted the Local Patent Rules and has served as the district's principal claim-construction magistrate.

No published Lex Machina, Unified Patents, or Reuters analysis supports classifying any N.D.N.Y. judge as plaintiff- or defendant-leaning, and I have not asserted one.
