2026 — Q4 (October 3, 2026)

New pages, accuracy corrections, and clarifications

New pages: Which court hears patent cases?, Local patent rules compared, Eastern District of Texas Patent Rules, N.D. Cal. Patent Local Rules, Contributory infringement, All-elements rule, Graham v. John Deere Co., Supreme Court § 101 cases, IPR timeline, and a Reference section page. Frequently asked questions added to the most-read pages.

Accuracy corrections: the Eastern District of Texas page now describes the district's Patent Rules (P.R., Local Rules App. M) correctly, including that they followed rather than preceded the Northern District of California rules and that Delaware has no local patent rules; contention timing on the discovery page is now stated per district; the Phillips page now lists the separate opinions correctly; the IPR page no longer states that § 315(b) rulings are appealable (Thryv, 2020); the Octane Fitness vote note now reflects footnotes 1–3; an uncertain citation to In re TracFone and an uncertain fee-award citation were removed; the willfulness page now states that the effect of post-suit-only knowledge is unsettled; PTAB pages note the 2025 changes to discretionary-denial and institution practice.

Site notices: clarified throughout that Patent Court is an independent reference, not a court or an official court website, and corrected the privacy statement to disclose the use of Google Analytics (see About — Privacy).
