US District Court, California Northern District Court

The U.S. District Court for the Northern District of California (NDCA) is a federal trial court within the Ninth Circuit, with its headquarters in San Francisco and additional courthouses in Oakland, San Jose, and Eureka. Its jurisdiction covers a significant portion of California's coastal region, including the technology-rich Silicon Valley. Historically, the NDCA has been a prominent venue for patent litigation, often ranking among the top federal districts for patent filings. While patent filings surged after the 2017 TC Heartland Supreme Court decision, they have since seen a decline, with 105 new patent cases filed in 2025, placing it tenth nationally, and 312 cases in 2022, representing 9% of national filings for that year.

The NDCA is generally not considered a "rocket docket" but offers a balanced approach to patent disputes, particularly favoring patent defendants in certain aspects. It is one of the most favorable venues in the country for pleadings-stage dismissals under Fed. R. Civ. P. 12(b)(6), granting 49.2% of such motions since 2020 and 53.7% in 2025. The court also demonstrates a willingness to grant summary judgment motions related to infringement or validity, with a 34.1% overall grant rate. Judges in the NDCA often view early dispositive motion practice favorably, frequently granting Alice motions challenging patent eligibility, with a grant rate exceeding 70% in 2024 and 80% in 2025. The court also tends to grant motions to stay cases pending inter partes review (IPR) before the USPTO, especially for pre-institution stays, granting 80% of stay motions in 2024.

The Northern District of California pioneered the use of local rules for patent cases, with other districts often modeling their rules after the NDCA's. These Patent Local Rules (Patent L.R.) regulate the procedure in patent infringement cases from filing through claim construction, requiring detailed infringement and invalidity theories early in the case. Distinctive standing orders from individual judges, such as Judge Saundra Brown Armstrong, Judge Yvonne Gonzalez Rogers, Judge Jeffrey S. White, and Judge Eumi K. Lee, often supplement these rules, typically limiting the number of terms to be construed to ten and requiring a truly joint claim construction statement with each party's proposed construction and support presented side-by-side. Many judges also require a tutorial on the technology at issue before the claim construction hearing, often presented by someone other than counsel. The local rules also mandate patentees to serve damages contentions within 50 days of receiving the defendant's invalidity contentions, aiding early case valuation.

While no specific named cases are listed as "tracked" in the provided data beyond an "Untitled case," the NDCA has been the venue for numerous high-profile patent disputes, particularly involving technology companies. Notable rulings from the court include decisions on patent eligibility under 35 U.S.C. § 101, such as Judge William H. Orrick's ruling in Wisk Aero LLC v. Archer Aviation and Judge James Donato's grant of an Alice motion in Broadcom Corp. v. Netflix Inc. In Longitude Licensing Ltd. v Google, LLC, Judge Chhabria dismissed a complaint based on patent ineligibility, a decision later affirmed by the Federal Circuit in April 2025. The court has also seen jury verdicts in significant cases, such as in Omnitracs, LLC, et al. v Motive Technologies, Inc. where a jury found no infringement of four patents in April 2025.

The NDCA bench includes judges with significant patent litigation experience. Prominent judges who have handled patent cases or served on relevant committees include Judge Beth Labson Freeman, who sits in the San Jose Division and serves on the Northern District's patent local rules and jury instruction committees, and Judge James Donato, who is a member of the Local Rules Committee and Patent Pilot Program. Judge William H. Orrick and Judge Yvonne Gonzalez Rogers are also noted for their patent rulings. Judge Lucy Koh, who was elevated to the Federal Circuit, was previously a key figure in patent litigation in the NDCA, notably presiding over the Apple v. Samsung patent suits. The court also appointed patent litigator Peter H. Kang as a U.S. Magistrate Judge in December 2022.
