D.N.J.

I'll gather sourced data on the District of New Jersey's patent practice before writing.

District of New Jersey — Patent Litigation Profile

Court overview. The U.S. District Court for the District of New Jersey (D.N.J.) sits in the Third Circuit, with three vicinages — Newark, Trenton and Camden — and is one of the largest district benches in the country (the district was described as having 24 Article III judges and 12 magistrate judges in a Law360/Cooley venue survey, and IAM reported in February 2025 that it had no judicial vacancies, which practitioners cited as a draw). It is a top-tier patent venue but not the largest: Docket Navigator data reported by IAM showed 232 patent cases filed in D.N.J. in 2024, a 77% year-over-year increase and the district's highest total since 2015, making it the fifth-most-popular patent venue nationally that year — its best ranking since 2018. Its volume is heavily pharmaceutical: in 2024, for the first time in a decade, New Jersey (51%) overtook Delaware (42%) in new ANDA/Orange Book cases.

Docket reputation. D.N.J. is not a "rocket docket." An older Law360/Cooley venue comparison put the district's median time to trial for civil cases at 38.5 months — the longest of the districts studied — and reported patentee trial success at roughly 50% versus a 57% national average; those figures are dated (circa 2010) and should be re-verified against current Docket Navigator or Lex Machina data. The district also has not historically been a PAE magnet: a Buffalo Law Review study of 2014–2016 patent filings found that about 82% of D.N.J. patent plaintiffs were product companies and only ~2% were PAEs, essentially the mirror image of the Eastern District of Texas in the same period, and that roughly 4% of D.N.J. patent cases reached trial (versus 0.6% in E.D. Tex.), with about 19.8% of cases generating a written opinion. On outcomes, research cuts both ways: Lemley's outcome-adjusted pro-plaintiff rankings placed D.N.J. near the bottom of 33 districts, while Lemley & Melamed's later study identified Delaware and New Jersey as districts comparatively likely to find for patentees on infringement. I could not verify a published district-specific § 1404(a) transfer-grant rate from the sources retrieved; any transfer-practice claim should be checked against Lex Machina or Docket Navigator rather than asserted here.

Local rules and procedures. D.N.J. has full Local Patent Rules (L. Civ. R. 9.3), effective January 1, 2009 and amended (notably adding L. Pat. R. 4.3(f) in 2011), which apply to infringement claims and to declaratory-judgment actions of non-infringement, invalidity or unenforceability. They are the district's most distinctive procedural feature. Infringement contentions are due 14 days after the initial scheduling conference; non-infringement and invalidity contentions follow 45 days later; the claim construction sequence (L. Pat. R. 4.1–4.6) requires exchanges of proposed terms, preliminary constructions with intrinsic and extrinsic evidence, responsive evidence, a Joint Claim Construction and Prehearing Statement, and a Markman hearing "to the extent such a hearing is necessary." Rule 4.3(f) bars evidence not timely disclosed, and judges enforce it by striking late claim-construction positions (e.g., Bristol-Myers Squibb v. Dr. Reddy's, 2021 WL 1820486 (D.N.J. May 6, 2021); see also a 2025 D.N.J. opinion striking an expert from a JCCS for disclosure violations). The rules also contain Hatch-Waxman-specific provisions (L. Pat. R. 3.6) that reverse the usual sequence — the ANDA defendant serves non-infringement and invalidity contentions early and must produce its ANDA/NDA shortly after responding — a structure commentators have described as favoring the brand plaintiff. Appendix S supplies a model discovery confidentiality order, and Appendix T / L. Civ. R. 40.1(f) governed patent-case assignment under the Patent Pilot Program, in which D.N.J. was one of the original 14 districts with a list of designated patent judges; I could not confirm from the sources retrieved whether that assignment mechanism is still operative.

Notable tracked cases and trends. The tracked docket is dominated by two matters. GEOTAB Inc. et al. v. Fleet Connect Solutions LLC (D.N.J., filed May 13, 2024, assigned to Judge Stanley R. Chesler) is a 20-patent declaratory-judgment action of non-infringement — a defensive DJ filed by Geotab after Fleet Connect, a New Jersey-registered entity, sued Geotab's telematics customers (LKQ, Enterprise, Orkin, Wheels) in other districts; parallel DJ actions were filed by other accused parties in other venues. Secondary reporting reproducing the PACER docket indicates the case was administratively terminated on November 5, 2024 after settlement was reported, with a 60-day window to file dismissal papers — so the "pending" status in the tracked list may be stale. The Cedar Lane Technologies matters (v. KTC America, Hanwha Techwin America, Zicom Technology, Leica Camera, ZKTeco USA) reflect that prolific NPE's 2022 filing campaign in the district; the tracked outcomes are settlement or dismissal (several without prejudice), with no merits rulings recorded.

Judges. Reliably identifiable patent-side judges from the district's Patent Pilot designation and case assignments include: Stanley R. Chesler (Newark; designated patent judge; handled the Geotab DJ and authored the damages opinions in Mondis Technology v. LG Electronics, vacating a $45M jury award on apportionment grounds and ordering a new damages trial); Chief Judge Renée M. Bumb (Camden; designated patent judge and current chief judge); Claire C. Cecchi (Newark; designated patent judge); and Noel L. Hillman (Camden; designated patent judge, former chief judge). Michael A. Shipp (who authored the Local Patent Rules enforcement opinion cited above) appears in the district's patent caseload as well. Note that the designation list dates to 2011 and several designees (e.g., Faith S. Hochberg, Joel A. Pisano, Mary L. Cooper, Jerome B. Simandle) have since retired or taken senior status; a current judge-by-judge confirmation should be run against the district's website. I found no published Lex Machina, Unified Patents or Reuters analysis that characterizes an individual D.N.J. judge as plaintiff- or defendant-leaning, and none should be inferred here.
