Route Guidance Systems v. Grubhub: Patent Infringement Action Dismissed After 1,261 Days
Route Guidance Systems LLC, a Delaware patent-holding entity, sued Grubhub Inc. in the Northern District of Illinois asserting US6917876B2 — a route guidance patent — against Grubhub’s Driver App and supporting server infrastructure. The case ran for over three and a half years before being dismissed.
A Route Guidance Patent Asserted Against a Food Delivery Giant
Filed on 2 May 2022 in the Northern District of Illinois, Route Guidance Systems LLC (‘RGS’) brought a patent infringement action against Grubhub Inc. under 35 U.S.C. § 1 et seq. RGS, organised under Delaware law with a stated address in Atlantic City, NJ, alleged that Grubhub’s back-end servers and the Grubhub Driver App infringed US6917876B2, a patent covering route guidance system technology. The case was assigned to Judge John F. Kness.
The case was terminated on 14 October 2025, with the public record recording a dismissal. The basis of termination is listed as ‘Case Dismissed,’ but the available record does not specify whether the dismissal was with or without prejudice, or whether it was voluntary or court-ordered. This distinction carries significant legal weight — a dismissal with prejudice bars re-filing, while one without prejudice preserves the plaintiff’s right to bring the same claims again.
At 1,261 days, the case’s duration suggests substantive litigation activity before resolution, potentially including claim construction or summary judgment proceedings, though the public record does not confirm this. The involvement of Fish & Richardson PC — a prominent IP litigation firm — on Grubhub’s defence side suggests the case was contested. What drove the ultimate dismissal, and whether any commercial resolution accompanied it, remains unknown from the public record.

Case dismissed: what the termination means for RGS and Grubhub
Dismissal without a stated basis — what the record shows
The public record designates this case as ‘Case Dismissed’ without specifying the procedural basis. A dismissal can arise under Rule 41(a) (voluntary, by the plaintiff), Rule 41(b) (involuntary, by court order), or following a dispositive ruling. Without further detail, the precise mechanism — and which party, if any, prevailed on the merits — cannot be confirmed from the available data.
Basis of termination unspecifiedWith or without prejudice? The public record is silent
This distinction matters materially. A dismissal with prejudice operates as a final adjudication on the merits — RGS would be barred from re-asserting US6917876B2 against Grubhub on the same claims. A dismissal without prejudice leaves that door open. The available public record does not specify which applies here, and practitioners should consult the docket directly before drawing conclusions about RGS’s ability to refile.
Prejudice status: not confirmedGrubhub exits litigation — but on what terms?
Grubhub, defended by Fish & Richardson PC and Goldberg Kohn Ltd., secured the termination of a case that had run for over three and a half years. However, absent confirmation that the dismissal was with prejudice or followed a merits ruling in Grubhub’s favour, it is premature to treat this as a full vindication. A confidential settlement that included a licence to US6917876B2 would also appear as a dismissal in the public record.
Grubhub: litigation ends, terms unclearRoute guidance IP and the gig-economy delivery sector
The assertion of a route guidance patent against food delivery logistics infrastructure signals that navigation and routing technology remains a live enforcement area for gig-economy platforms. Other operators running proprietary driver-dispatch or route-optimisation systems — including competitors in the food delivery and on-demand logistics space — should monitor the status of US6917876B2 and assess exposure, particularly if the dismissal was without prejudice.

Official order — verbatim text
The complaint’s language establishes the standard elements of a patent infringement action under 35 U.S.C. § 1 et seq., identifying Grubhub’s Driver App and back-end servers as the accused products. Notably, the operative record terminates with a dismissal rather than a merits adjudication, meaning the substantive infringement claims — validity, claim scope, and alleged acts of infringement — were never publicly resolved. The dismissal does not constitute a finding of non-infringement or invalidity, and neither party can be said to have prevailed on the merits based solely on the available public record.
US6917876B2 — Route Guidance System Technology
US6917876B2 was filed under application number US10/138418 and issues as a granted utility patent covering route guidance system technology. Route guidance patents in this generation typically protect methods and systems for dynamically computing and transmitting navigation instructions to mobile users — technology directly applicable to driver-dispatch and logistics platforms. The patent’s application date and grant history place it within an era of foundational navigation system innovation, predating the widespread adoption of smartphone-based delivery applications.
The assertion of US6917876B2 against Grubhub’s Driver App and server infrastructure demonstrates the continuing relevance of first-generation navigation and routing patents to modern gig-economy platforms. Companies operating driver-side mobile applications, real-time route computation engines, or logistics coordination systems face potential exposure to patents of this vintage — particularly where the claims are drafted broadly enough to capture server-side route guidance functionality. This case reinforces the need for proactive FTO analysis across the route guidance patent landscape for any platform managing last-mile delivery logistics.
Should your logistics platform run an FTO against US6917876B2?
Any company operating a driver-dispatch application, real-time route guidance system, or logistics coordination platform in the United States should assess its exposure to US6917876B2. The Grubhub litigation demonstrates that back-end servers and mobile driver apps are squarely within the scope of enforcement activity for this patent. Food delivery platforms, ride-hailing operators, and on-demand logistics companies are the most directly at-risk product categories.

Portfolio viewWhat this case signals for the food delivery and logistics IP landscape
A route guidance patent asserted against Grubhub’s Driver App raises questions that extend well beyond one food delivery platform.
Routing and navigation patents remain enforceable against logistics platforms
US6917876B2 was asserted against Grubhub’s Driver App and back-end servers — infrastructure common to virtually every gig-economy delivery operator. Companies running proprietary dispatch, routing, or navigation systems should treat this case as a prompt to audit their exposure to legacy route-guidance patent portfolios.
Three-and-a-half year duration signals substantive contested litigation
Cases that run 1,261 days before dismissal typically involve meaningful procedural activity — claim construction, early summary judgment, or extended discovery. The retention of Fish & Richardson PC by Grubhub suggests the defence was prepared to litigate on the merits. IP teams facing similar assertions should prepare for a long timeline and experienced opposition counsel.
Prejudice status of dismissal determines RGS’s future enforcement options
If the dismissal was without prejudice, RGS retains the ability to refile against Grubhub or bring parallel actions against other food delivery platforms. Competitors and licensing targets of RGS should monitor the docket closely and consider whether a proactive declaratory judgment strategy is warranted to achieve certainty on the ‘876 patent.
US6917876B2 may anchor a broader assertion campaign — track the portfolio
Patent-holding entities like RGS frequently assert a single patent as a lead instrument while holding related continuations or divisionals. A full portfolio analysis of the application number US10/138418 and its family members is advisable for any company operating driver-side routing or dispatch technology in the United States.
