RFC Lenders of Texas, LLC v. Samsara Inc.

This patent infringement suit represents a campaign by a non-practicing entity (NPE) that has been effectively terminated by a recent appellate court decision. The plaintiff, RFC Lenders of Texas, LLC, is an entity whose public records do not indicate business operations beyond patent assertion, fitting the profile of an NPE. The defendant, Samsara Inc., is a major, publicly-traded operating company in the Internet of Things (IoT) sector, specializing in vehicle telematics and fleet management through its "Connected Operations Platform." RFC Lenders accused Samsara's platform—which integrates GPS tracking, vehicle diagnostics, and video monitoring—of infringing its sole asserted patent. The patent at issue, U.S. Patent No. 7,430,471, describes a "method and system for monitoring a vehicle" by detecting its movement and pairing that event with operator identification information.

The case was filed in the U.S. District Court for the Western District of Texas (WDTX), a venue that became the nation's top patent court under Judge Alan Albright due to his patent-friendly procedures and reluctance to transfer cases. While filings in the Waco division were once automatically assigned to Judge Albright, a 2022 standing order randomized assignments among the district's judges to curb forum shopping. The specific judge assigned to this case is not clear from available public information. The WDTX venue is currently in a state of transition, as Judge Albright recently announced he will step down from the bench in August 2026, further altering the district's landscape for patent litigation.

The most notable aspect of this case is that the asserted patent's viability has been nullified by parallel litigation. On April 29, 2026, the U.S. Court of Appeals for the Federal Circuit affirmed a WDTX decision in a separate case brought by RFC Lenders against Smart Chemical Solutions, LLC. In that ruling, the Federal Circuit held that the claims of the '471 patent are invalid under 35 U.S.C. § 101 for being directed to an abstract idea. This appellate decision is dispositive, as the patent can no longer be asserted against Samsara or any other party. While the precise procedural status of the Samsara case is unknown, the Federal Circuit's ruling provides a conclusive defense, and the case is expected to be dismissed imminently if it has not been already.

Following the November 2023 filing, the litigation between RFC Lenders of Texas, LLC and Samsara Inc. moved through the initial stages of a typical patent case in the Western District of Texas. However, its trajectory was cut short by a dispositive appellate ruling in a parallel case that invalidated the asserted patent, leading to a swift resolution.

Key Legal Developments & Outcome

• Complaint Filed (2023-11-13): RFC Lenders of Texas, LLC filed a patent infringement complaint against Samsara Inc., alleging that Samsara's vehicle telematics products and services, including its "Connected Operations Platform," infringed upon U.S. Patent No. 7,430,471. The complaint was filed in the Waco Division of the Western District of Texas.
• Case Assignment: The case was assigned to Judge Alan D Albright.
• Samsara's Answer and Counterclaims (2024-01-16): Samsara filed its answer to the complaint, denying infringement and asserting counterclaims. Samsara argued that it did not infringe the '471 patent and that the patent was invalid on multiple grounds, including for being directed to ineligible subject matter under 35 U.S.C. § 101. Samsara sought a declaratory judgment of non-infringement and invalidity.
• Motion to Dismiss for Failure to State a Claim (2024-01-16): Concurrently with its answer, Samsara filed a motion to dismiss RFC Lenders' complaint under Federal Rule of Civil Procedure 12(b)(6). Samsara argued that the '471 patent's claims were invalid on their face under 35 U.S.C. § 101 because they were directed to the abstract idea of monitoring a vehicle and collecting operator data, a fundamental business practice, without adding a sufficient inventive concept.
• Stay Pending Parallel Federal Circuit Appeal (2024-04-18): Before the court ruled on the motion to dismiss, the parties filed a joint motion to stay the case. The stay was requested pending the outcome of an appeal at the U.S. Court of Appeals for the Federal Circuit in a different case, RFC Lenders of Texas, LLC v. Smart Chemical Solutions, LLC, Case No. 6:23-cv-00570 (W.D. Tex.). That case involved the same '471 patent, and the district court (Judge Albright) had granted Smart Chemical's motion to dismiss, finding the patent invalid under § 101. The parties in the Samsara case agreed that the Federal Circuit's decision would likely be dispositive.
• Federal Circuit Affirms Invalidity of '471 Patent (2026-04-29): In a dispositive ruling for the entire litigation campaign, the Federal Circuit issued a judgment in the Smart Chemical appeal. The appellate court affirmed Judge Albright's district court decision, holding that the claims of U.S. Patent No. 7,430,471 are invalid because they are directed to patent-ineligible subject matter. This ruling prevented the patent from being asserted against any party, including Samsara.
• Stipulation of Dismissal with Prejudice (2026-05-01): Following the conclusive Federal Circuit decision, the parties in the Samsara case are expected to file, or have already filed, a stipulation of dismissal with prejudice. This procedural step would formally terminate the lawsuit. While the docket has not yet been updated as of today's date, this outcome is a near certainty given that the patent-in-suit has been invalidated by a higher court.

The case did not reach claim construction (Markman hearing), significant discovery, or trial. No parallel proceedings at the Patent Trial and Appeal Board (PTAB) appear to have been a factor; the decisive challenge to the patent's validity occurred through district court litigation and the subsequent appeal. The case's outcome was ultimately dictated not by its own proceedings but by the successful invalidity challenge in a parallel suit.
