N.D. Cal. (transferred from E.D. Tex.)

I'll research the court's profile before writing.

N.D. Cal. — Patent Litigation Profile

Court overview. The U.S. District Court for the Northern District of California sits in the Ninth Circuit, with courthouses in San Francisco, Oakland, San Jose, and Eureka. Patent appeals go to the Federal Circuit, not the Ninth. The district was once the nation's patent-filing leader, but its docket is now mid-sized: filings fell from a post-TC Heartland high of roughly 330 in 2018 to about 113 in 2024, with only 24 cases filed through March 2025 (Skadden analysis published in Bloomberg Law, Northern California Offers a Friendly Venue for Patent Defenders, Apr. 16, 2025). By contrast, Lex Machina's 2025 Patent Litigation Report shows the W.D. Tex., D. Del., and E.D. Tex. together took just over half of all U.S. patent filings in 2021–2023. The single case this site tracks at N.D. Cal. — Avago Technologies General IP (Singapore) Pte. Ltd. v. ASUSTeK Computer, Inc., No. 3:15-cv-04525 (N.D. Cal.), which settled — is a § 1404(a) transferee from the E.D. Tex. (originally Avago v. ASUSTeK, No. 2:15-cv-00239-JRG, Marshall Division). One case cannot support any court-level outcome statistics, so nothing here about win rates is drawn from this site's data.

Docket reputation. N.D. Cal. is not a "rocket docket." Its Patent Local Rules build in more claim-construction time than the Texas districts — roughly 220 days from the Rule 26(f) conference to resolution of claim construction, versus about 201 days in E.D. Tex. and 161 days in W.D. Tex. (Hsieh, Mississippi Law Journal). Contemporary analysis characterizes it in defendant-friendly terms rather than plaintiff-friendly ones. Skadden's April 2025 Bloomberg Law article reports that N.D. Cal. judges granted Alice/§ 101 motions more than 70% of the time in 2024 and 80% of the time in early 2025, and granted 80% of motions to stay pending IPR in 2024 (14 of 20 grants were pre-institution). That is law-firm analysis rather than an independent Lex Machina or Unified Patents study, so treat the percentages as directional. Patent trials — jury and bench — remain rare relative to filings; I did not find a reliable, current N.D. Cal.-specific average time-to-trial figure. (Lex Machina's national median time to trial for non-ANDA patent cases terminated 2022–2024 was 1,040 days.)

Local rules and procedures. N.D. Cal. adopted Patent Local Rules in December 2000 and is the model from which the E.D. Tex. rules were largely borrowed. Rules 3-1 through 3-4 require early infringement and invalidity contentions with element-by-element charts; amendment requires "good cause," a standard courts apply more strictly than the Texas rules — a point litigated at length in the Avago case after transfer. Amendments effective January 2017 (L.R. 3-8, 3-9) added damages contentions: the patentee serves damages contentions within 50 days of invalidity contentions, the accused infringer responds 30 days later, and the parties exchange non-binding good-faith damages estimates. Claim construction under L.R. 4-3 and 4-5, plus individual standing orders, generally caps construction at ten terms and pairs a technology tutorial with the Markman hearing. Standing orders of Judge Yvonne Gonzalez Rogers (rev. Mar. 13, 2024), Judge Edward J. Davila, and Senior Judge Saundra Brown Armstrong (eff. Oct. 1, 2018) follow this pattern and disfavor live claim-construction testimony. The district is also known for a strict good-cause standard on amending contentions and for the use of magistrate judges for discovery referrals.

Notable cases and judges. The tracked matter, Avago v. ASUSTeK, was assigned to Judge Edward M. Chen, whose rulings on leave to amend infringement contentions after transfer from Texas are a useful illustration of how N.D. Cal.'s local rules differ from E.D. Tex.'s. Historically the district's highest-profile patent matters include Apple Inc. v. Samsung Electronics Co., No. 11-cv-01846-LHK (Judge Lucy H. Koh; now on the Ninth Circuit), which produced some of the largest patent damages awards in U.S. history before a 2018 settlement, and Oracle America, Inc. v. Google LLC (Judge William Alsup), in which the patent claims were resolved before trial. Prominent patent-handling judges whose practices are documented by published standing orders include Judge Yvonne Gonzalez Rogers, Judge Edward J. Davila, and Senior Judge Saundra Brown Armstrong; Judge Chen's patent docket is documented in the tracked case. Skadden notes seven new N.D. Cal. judges appointed since 2022, several from large-firm litigation backgrounds — a bench-composition shift I have not seen independently quantified for patent outcomes.
