Plaintiff
1 case as plaintiff.
Route Guidance Systems LLC is a Delaware-formed patent-holding entity established on February 15, 2019. It has no public ticker and no disclosed revenue or headcount; in court disclosures it identifies Equitable IP Corporation / Equitable IP Holdings, LLC as its parent. It is not an operating company — Stanford's NPE database classifies it as a patent asserter relying on "acquired patents," and Unified Patents describes it as an NPE. It should be treated as a non-practicing entity / patent assertion vehicle with no products or services.
Portfolio asserted. The entity's campaign rests on a single patent, U.S. 6,917,876 ("Route Guidance for Vehicles"), covering centralized route calculation transmitted to a vehicle over a communication channel opened in a "short burst" and then closed. The patent issued July 12, 2005 to Teletrac Navman (UK) Ltd. (then Trafficmaster), with a May 2001 priority date and an estimated expiry of May 2022. Equitable IP Holdings acquired it from Teletrac Navman in January 2018 and transferred it, with European and UK counterparts, to Route Guidance Systems on February 26, 2019. Counsel of record is Devlin Law Firm LLC.
Litigation posture. The tracked data shows one plaintiff-side case and zero defendant-side cases, consistent with a pure plaintiff/NPE filer. The sole tracked matter is Route Guidance Systems LLC v. Microsoft Corporation (1:22-cv-02278), filed May 2, 2022 in the Northern District of Illinois, Eastern Division, and voluntarily dismissed with prejudice on August 22, 2022, each side bearing its own costs. The Microsoft suit was one of a nine-defendant wave filed in N.D. Ill. in May 2022; earlier rounds were filed in the District of Delaware in 2019 (Lyft, Uber) and February 2022 (DoorDash, Instacart/Maplebear, Waitr), so filings cluster in Delaware and Illinois rather than the Eastern District of Texas.
Broader context. External reporting and Unified Patents document assertions against ExxonMobil, Verizon, Honda, Huawei, Salesforce, Grubhub, HERE Global, MyPizza Technologies and others. Unified's ex parte reexamination (90/015,113) produced a final rejection of all '876 claims in August 2023, confirmed by the PTAB on July 18, 2025.

Route Guidance Systems LLC filed a patent-infringement suit against Microsoft Corporation in the Northern District of Illinois. The narrative identifies this as an unverified lead because it could not confirm that US10145697 was among the asserted patents; the plaintiff voluntarily dismissed the case in August 2022.
