N.D. Cal.

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

U.S. District Court for the Northern District of California — Patent Litigation Profile

Court overview. The U.S. District Court for the Northern District of California (N.D. Cal.) sits in the Ninth Circuit, with courthouses in San Francisco (headquarters), Oakland, San Jose, and Eureka; because it covers Silicon Valley, its patent docket is dominated by software, semiconductor, networking, and consumer-electronics disputes. Patent filings here rose sharply after TC Heartland v. Kraft Foods (2017) — peaking at roughly 330 new patent cases in 2018 — but have fallen steadily since: about 113 new patent cases in 2024, and only 24 through March 2025, down ~20% year over year (Skadden white paper, Bloomberg Law US Law Week, Apr. 16, 2025). On the district-level rankings, N.D. Cal. is no longer a top-three patent venue: W.D. Tex., D. Del., and E.D. Tex. have accounted for more than half of all U.S. patent filings in recent years (Lex Machina 2024/2025 Patent Litigation Reports), with E.D. Tex. leading all districts in new filings in both 2023 and 2024. Public aggregator dockets show several thousand cumulative patent filings in N.D. Cal.; I did not retrieve current AOUSC Table C-4 figures for this session, so the annual numbers above should be attributed to the secondary sources cited.

Docket reputation. N.D. Cal. is not a "rocket docket." Older Law360/Cooley venue analysis put median civil time-to-trial at roughly 30 months and reported one of the lower patentee trial-win rates among major districts (57.5%), and Lex Machina-cited data (White & Case, 2020) showed the district's median times to case milestones tracking national averages rather than Texas-style speed. Jury trials dominate: in the Stanford/Lemley trial dataset, 27 of 33 N.D. Cal. patent trials were jury trials, with patentees winning 44.4% and accused infringers 48.1%. The venue's recent reputation has tilted toward defendants on pretrial motions rather than at trial: according to the same Skadden/Bloomberg Law analysis, N.D. Cal. judges granted Rule 12(b)(6) Alice § 101 motions in more than 70% of 2024 rulings, 100% in 2023, and ~80% year-to-date 2025, and granted 80% of motions to stay pending IPR in 2024 — 14 of the 20 grants being pre-institution stays. Those figures come from a defense-oriented law-firm analysis, not an independent statistical agency, and should be read with that caveat. On venue, the district is now both a source and a target of § 1404(a) transfer litigation; it remains a plausible transferee for defendants seeking a technically sophisticated bench.

Local rules and procedures. N.D. Cal. adopted patent local rules in 2000, making it one of the earliest such districts, and its rules (currently available at cand.uscourts.gov/localrules/patent, with revisions including Nov. 4, 2020 and later 2023 amendments) are among the most frequently cited models nationwide. Patent L.R. 3-1/3-2 require infringement contentions and accompanying document production shortly after the initial case management conference; L.R. 3-3/3-4 require invalidity contentions within 45 days thereafter; and L.R. 3-6 permits amendment of contentions only by leave on a showing of good cause — a deliberately conservative standard. L.R. 3-7 governs advice-of-counsel disclosures after claim construction. Distinctively, L.R. 3-8 through 3-10 require damages contentions (each damages category with a good-faith theory), served within 50 days of the defendant's invalidity contentions, with responses in 30 days and a damages meet-and-confer at 60 days — a feature aimed at early case valuation. Claim construction under L.R. 4-1 to 4-6 requires the parties to jointly identify no more than ten most-significant terms, followed by a Joint Claim Construction and Prehearing Statement, claim construction discovery, and briefing (roughly a 220-day claim-construction track from the Rule 26 conference). Individual judges supplement these with standing orders — e.g., Judge Jeffrey S. White's patent standing order enforced the ten-term limit. The district also publishes model patent jury instructions.

Notable tracked cases and public rulings. The tracked CyboEnergy, Inc. v. Duracell Power Center, LLC, No. 3:24-cv-08891 (N.D. Cal., filed Dec. 10, 2024), asserts U.S. Patent Nos. 9,331,488 and 9,331,489 (solar inverter status-messaging and low-light power maximization) against Duracell's solar micro-inverters; it was filed with a jury demand by Ramey LLP and is assigned to Magistrate Judge Lisa J. Cisneros, and remains pending. The second tracked entry, Sol IP, LLC v. [defendant — unconfirmed], is unverified: public dockets show Sol IP's N.D. Cal. activity as ancillary subpoena-enforcement litigation (e.g., Sol IP LLC v. Intel Corp., No. 5:20-cv-00399, a motion to compel compliance with a subpoena connected to its E.D. Tex. suits), not an infringement action, so that entry should not be treated as a confirmed N.D. Cal. patent case. Other publicly prominent N.D. Cal. patent matters include VLSI Technology LLC v. Intel Corp., No. 5:17-cv-05671-BLF (Judge Beth Labson Freeman) and Power Integrations v. Fairchild Semiconductor, in which a reported ~$105M award was entered in 2014; I could not verify current verdict or damages figures for these in this session. N.D. Cal. also produced high-profile § 101 jurisprudence and, historically, some of the largest patent damages awards, though current-year aggregate damages data for the district were not independently verified here.

Judges. N.D. Cal. does not concentrate patent cases in one or two hands: Lex Machina data reported in 2020 showed no individual judge receiving more than 22 of 240 new patent filings, and none of the ten judges nationwide with the largest patent dockets sat in N.D. Cal. — a structural contrast with E.D. Tex. and W.D. Tex. Judges with substantial, publicly documented patent experience include Judge Beth Labson Freeman (VLSI v. Intel), Judge Jeffrey S. White (a published patent standing order and contested ten-term claim-construction ruling in Fortinet v. SRI International), Judge William Alsup (long tenure and numerous § 101 and claim-construction rulings), and Judge James Donato (who presided over the FTC v. Qualcomm bench trial). Judges are drawn into patent work by the district's district-wide random assignment rules (Civil L.R. 3-2(c)) rather than a specialized patent calendar, and several patent cases — including the tracked CyboEnergy matter — are handled by magistrate judges such as Judge Cisneros. I did not identify independent Lex Machina, Unified Patents, or Reuters rankings labeling any current N.D. Cal. judge as distinctly plaintiff- or defendant-friendly, and I have avoided such characterizations for that reason.
