N.D. Cal. (Judge James Donato)

I'll research this court's patent litigation profile before writing.

Let me dig deeper on transfer practice, local rules, and notable N.D. Cal. patent judges and cases.

Now let me verify the tracked case and N.D. Cal.'s prominent patent judges and time-to-trial data.

N.D. Cal. — Patent Litigation Profile (Judge James Donato)

Court overview. The U.S. District Court for the Northern District of California sits in the Ninth Circuit, with courthouses in San Francisco (450 Golden Gate Ave.), Oakland, and San Jose; patent appeals go to the Federal Circuit. It is a high-volume IP court in absolute terms but not a leading patent venue: Justia's docket lists roughly 4,700 intellectual-property cases (all IP types), while patent filings specifically have fallen sharply since TC Heartland — from a post-2017 peak of about 330 in 2018 to roughly 113 in 2024, with only 24 patent cases filed through March 2025 (Bloomberg Tax/Law, April 2025). That places it well behind the Western and Eastern Districts of Texas and the District of Delaware, which together draw over half of U.S. patent filings (Lex Machina 2024 Patent Litigation Report). LexisNexis data show N.D. Cal. averaging about nine SEP cases per year over 2014–2024, versus 65/year in E.D. Tex.

Docket reputation. No — this is not a rocket docket, and it is not a plaintiff-friendly patent venue. One Lex Machina dataset (1,445 N.D. Cal. patent cases, Jan. 2018–May 2023, reproduced in a case exhibit) shows a median of 428 days from filing to claim construction hearing, and just 160 claim construction hearings across those cases — a slow, low-trial-volume profile. Reporting characterizes the district as defendant-leaning on dispositive motions: § 101 motions were granted more than 70% of the time in 2024 and 80% so far in 2025, and stay motions were granted in 80% of 2024 rulings, with 14 of 20 granted stays issued pre-institution (Bloomberg Tax/Law, April 2025). Defendants also frequently seek transfer to N.D. Cal.: in a Federal Circuit mandamus study covering 2008–2021, N.D. Cal. was the proposed transferee in 51 of 124 § 1404(a) petitions (41.1%), a higher share than any other district (Washington University Law Review, Vol. 100). Practitioners note that N.D. Cal. judges often take up early pleadings-stage § 101 motions before or alongside the initial case management conference, giving defendants an early exit that Texas venues historically did not.

Local rules and procedures. N.D. Cal.'s Patent Local Rules are among the oldest in the country and served as a model for other districts (E.D. Tex.'s rules were adapted from them). Patent L.R. 3-1 requires infringement contentions within 14 days of the initial CMC, with claim charts mapping each limitation to each accused instrumentality; Patent L.R. 3-3 requires invalidity contentions 45 days after service of infringement contentions; amendment requires a "timely showing of good cause" under Patent L.R. 3-6, and courts routinely strike or compel amendment of non-compliant contentions. Those rules are district-wide. Judge Donato adds individual standing orders, including a Standing Order for Claim Construction in Patent Cases — a genuinely joint claim construction statement, a presumptive ten-term limit (excess terms construed only by leave, under Civ. L.R. 7-11), 20/20/10-page brief limits, and an optional technology tutorial one to two weeks before the Markman hearing with 30–45 minutes per side and a strong preference for non-lawyer presenters — plus a separate Standing Order for E-Discovery and Email Discovery in Patent Cases. His general civil standing order trims briefs to 15 pages (opening/opposition) and 10 (reply), sets trial dates at the initial CMC, and targets roughly 18 months from CMC to trial. Note that third-party practice guides (LawSnap, aivortex) summarize these orders; the court's own site at cand.uscourts.gov/judges/standing-orders is the authoritative source and the orders change.

Notable tracked case and related rulings. The single tracked matter, FireNet Technologies, LLC v. Fortinet Inc., No. 4:19-cv-00798 (N.D. Cal., filed Feb. 14, 2019; reassigned to Judge Donato; closed Aug. 9, 2019, ~177 days), was a four-patent willful-infringement suit over Fortinet firewall and web-security products (FortiWeb, FortiGate, FortiADC). FireNet was an IP Investments Group NPE in a campaign in which Intellectual Ventures retained an interest (RPX). The patents did not survive elsewhere: Unified Patents' IPR2020-00471 resulted in a March 18, 2021 PTAB final written decision holding all claims of U.S. Patent 8,892,600 unpatentable. More broadly, the district's most-cited recent patent ruling is Judge Donato's § 101 summary judgment in Broadcom v. Netflix, invalidating a "network adapted to process data" patent and eliminating roughly 85% of Broadcom's claimed damages, after which Broadcom stipulated to dismiss the remaining patents (Daily Journal, May 2026). Other substantial N.D. Cal. patent dockets include Google v. Sonos / Sonos v. Google, Apple v. AliveCor, Netskope v. Fortinet, and Applied Materials v. Demaray.

Judges. N.D. Cal. has no specialized patent bench; patent cases are assigned randomly under General Order No. 44. Judge James Donato (appointed 2014; San Francisco, Courtroom 11) is the tracked-case judge, handles a heavy technology docket, serves on the court's Local Rules Committee, and is a Sedona Conference member — his claim-construction and e-discovery standing orders are the most patent-specific individual rules on the court. Beyond him, the district's most prominent patent dockets have historically included Judge William Alsup (Oracle v. Google, Waymo v. Uber), Judge Vince Chhabria, Judge Yvonne Gonzalez Rogers, and Judge Edward Chen; this list reflects case volume rather than any published plaintiff/defendant-leaning analysis, and I did not find Lex Machina, Unified Patents, or Reuters judge-level outcome data for N.D. Cal. to support characterizing any individual judge.

Caveats: figures above are drawn from third-party datasets (Lex Machina, LexisNexis, Docket Alarm reprints) and news reporting; I found no single authoritative AOUSC time-to-trial statistic specific to N.D. Cal. patent cases, and judge-level filing counts were not independently verified against the court's own statistics.
