Route Guidance Systems v. MapleBear: Shopper App Patent Dismissed With Prejudice
Route Guidance Systems, LLC asserted US6917876B2 against MapleBear, Inc. — the entity behind the Instacart Shopper App — in the Delaware District Court. The parties stipulated to a dismissal with prejudice of all plaintiff’s claims after nearly 1,358 days of litigation, with each side bearing its own costs.
A long-running Instacart Shopper App patent fight ends by stipulation
Route Guidance Systems, LLC filed suit against MapleBear, Inc. — the corporate parent of Instacart — in the District of Delaware on 9 February 2022, asserting infringement of US6917876B2. The patent relates to route guidance technology, and the accused product was the Instacart Shopper App, the driver-facing application used by Instacart’s delivery workforce. Judge Maryellen Noreika presided over the case.
The case closed on 29 October 2025 via a stipulated dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii). All of Route Guidance Systems’ claims against MapleBear were dismissed with prejudice, permanently barring refiling. MapleBear’s counterclaims were dismissed without prejudice, preserving the defendant’s ability to revive those claims in future proceedings. Each party agreed to bear its own legal costs and attorneys’ fees.
The 1,358-day duration suggests the matter survived early procedural hurdles and likely involved substantive motion practice before resolution. The with-prejudice dismissal of plaintiff’s claims — combined with cost neutrality — is consistent with a negotiated exit, though the precise terms driving settlement, if any, remain undisclosed on the public record. The asymmetric prejudice terms (plaintiff’s claims barred; defendant’s counterclaims preserved) is a notable structural feature of the stipulation.

Stipulated dismissal: what the with-prejudice ruling means for both parties
Rule 41(a)(1)(A)(ii): stipulated dismissal by agreement
A dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires the written consent of all parties. It is a procedural exit — not a judgment on the merits — but carries binding legal consequences where ‘with prejudice’ is specified. Here, plaintiff’s claims are permanently extinguished; the court need not issue findings on infringement or validity.
Procedural exit, no merits rulingWith-prejudice dismissal bars Route Guidance Systems from re-asserting these claims
Dismissal with prejudice of all plaintiff’s claims operates as a final adjudication against Route Guidance Systems for purposes of this action. Route Guidance Systems cannot refile the same infringement claims against MapleBear based on US6917876B2 in a future action. This is the most consequential concession a plaintiff can make short of a full defense verdict.
Claims permanently barredMapleBear’s counterclaims survive — dismissed without prejudice
MapleBear’s counterclaims — which may have included invalidity or unenforceability challenges to US6917876B2 — were dismissed without prejudice. This preserves MapleBear’s ability to revive those claims if circumstances warrant, such as if Route Guidance Systems asserts the same patent against a MapleBear affiliate or in a different jurisdiction. The asymmetry favours the defendant.
Counterclaims preservedCost neutrality suggests a negotiated resolution rather than a capitulation
The stipulation that each party bear its own costs and attorneys’ fees is consistent with a settlement in which neither side extracted a cost award. Combined with the with-prejudice/without-prejudice asymmetry, the structure suggests MapleBear secured favourable exit terms. Route guidance and location-based logistics patents remain commercially sensitive for gig-economy delivery platforms, and future assertion risk from related patents cannot be excluded.

Official order — verbatim text
The stipulation’s precise language — plaintiff’s claims dismissed with prejudice, defendant’s counterclaims dismissed without prejudice — creates a deliberately asymmetric outcome. The with-prejudice designation extinguishes Route Guidance Systems’ infringement claims against MapleBear as a matter of res judicata, while the without-prejudice carve-out for MapleBear’s counterclaims (likely invalidity and/or unenforceability) keeps those legal weapons available. The cost-neutrality clause prevents either party from leveraging a fee award. No merits findings were issued, leaving US6917876B2’s validity and infringement scope legally undetermined.
US6917876B2 — Route guidance system and method patent
US6917876B2 (application number US10/138418) covers route guidance technology — systems and methods for directing a user along a navigational path. Filed under a 10-series application number, this patent predates the smartphone era, suggesting it captures foundational concepts in turn-by-turn or optimised routing that may read broadly onto modern delivery and logistics applications. Its assertion against the Instacart Shopper App indicates the claims were argued to cover driver-facing routing or task-sequence navigation features.
Route guidance patents from this vintage present distinctive strategic risk: their broad, pre-smartphone claim language can be mapped onto contemporary delivery, ride-hailing, and logistics applications with relative ease. For any platform deploying shopper or driver routing interfaces — including last-mile delivery, grocery fulfilment, and on-demand logistics — US6917876B2 and its related family members warrant monitoring. The absence of a merits ruling here means the patent’s validity remains unchallenged on the public record.
Should you run an FTO analysis against US6917876B2?
Any company operating a driver-facing, shopper-facing, or delivery routing application should treat US6917876B2 as a live risk. The patent was asserted against one of the largest grocery delivery platforms in the US and survived nearly four years of litigation without a validity determination. Product and engineering teams building route optimisation, task sequencing, or turn-by-turn navigation features for gig-economy or logistics apps should assess claim coverage before scaling those features.
PatSnap Eureka’s FTO Search Agent can map the full claim scope of US6917876B2 against your product architecture, surface related patent family members held by Route Guidance Systems or affiliated entities, and identify prior art that was not adjudicated in this proceeding. Because this case closed without a merits ruling, an independent FTO analysis is the only reliable way to assess your exposure before deployment or investment decisions.

What this case signals for the logistics and delivery app IP landscape
Route guidance patent assertions against delivery platforms are increasing. This case offers a strategic blueprint for how defendants can structure a favourable exit.
Delivery platforms face growing route-guidance patent assertion risk
US6917876B2 targets the operational core of gig-economy apps — the shopper/driver routing interface. As delivery platforms scale, their patent exposure in navigation and route optimisation technology intensifies. In-house teams at logistics and delivery companies should audit their FTO posture against route guidance patent portfolios held by NPEs.
Asymmetric dismissal terms are a negotiating lever — not just a formality
The structure here — plaintiff’s claims out with prejudice, defendant’s counterclaims preserved without prejudice — is a tactically significant outcome for MapleBear. Defendants in NPE litigation should actively negotiate counterclaim preservation in any stipulated dismissal, as it provides a defensive shield if the same patent is reasserted elsewhere.
Route v MapleBear — key questions answered
The case was dismissed with prejudice as to all of Route Guidance Systems’ claims against MapleBear, and without prejudice as to MapleBear’s counterclaims, pursuant to a stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii). Each party agreed to bear its own costs and attorneys’ fees. No merits findings were issued.
Route Guidance Systems asserted US6917876B2 (application number US10/138418), a patent covering route guidance systems and methods. The accused product was the Instacart Shopper App, the driver and shopper-facing navigation interface used by Instacart’s delivery workforce.
Dismissal with prejudice operates as a final bar against Route Guidance Systems refiling the same infringement claims against MapleBear based on US6917876B2. The doctrine of res judicata would prevent a new suit on the same claims in US federal court. The patent itself remains in force and could theoretically be asserted against other defendants.
The parties stipulated to asymmetric dismissal terms. MapleBear’s counterclaims — which likely included invalidity or unenforceability challenges to US6917876B2 — were preserved by being dismissed without prejudice. This gives MapleBear the option to revive those claims if the patent is asserted again in a related context, providing a defensive advantage.
The case lasted 1,358 days (approximately 3.7 years) from filing in February 2022 to closure in October 2025. This duration is notably long and suggests the matter progressed beyond early motions, likely including claim construction proceedings. The eventual stipulated dismissal with cost-neutrality is consistent with a negotiated resolution reached after substantive litigation activity, though specific settlement terms are not public.
