InfoGation Corp. v. Subaru Corporation — Dismissed With Prejudice After 112 Days
InfoGation Corporation asserted four navigation patents against Subaru’s STARLINK Multimedia Navigation systems in the Eastern District of Texas. The parties jointly resolved all claims within 112 days — a timeline suggesting early negotiation — with the case dismissed with prejudice and each side bearing its own costs.
Four-patent navigation assertion against Subaru resolved in under four months
On May 14, 2024, InfoGation Corporation filed suit against Subaru Corporation in the Eastern District of Texas (Case No. 2:24-cv-00362) before Judge Rodney Gilstrap, asserting infringement of four U.S. patents — US8406994B1, US6292743B1, US10107628B2, and US8898003B1 — all relating to navigation system technology. The accused product was Subaru’s STARLINK Multimedia Navigation system, a core in-vehicle infotainment and navigation offering across multiple Subaru vehicle lines.
The case closed on September 3, 2024, just 112 days after filing. The parties filed a joint motion to dismiss representing that all of InfoGation’s claims for relief had been resolved. Judge Gilstrap granted the motion, ordering all claims dismissed with prejudice and directing each party to bear its own costs and attorneys’ fees. A dismissal with prejudice is a final adjudication on the merits, permanently barring InfoGation from re-asserting these specific claims against Subaru in future litigation.
The 112-day resolution is notably swift for a four-patent assertion in the Eastern District of Texas, a venue typically associated with lengthier pre-trial schedules. The joint nature of the motion and the mutual cost-bearing arrangement suggest the parties reached a private commercial resolution — likely a license or covenant not to sue — though the specific terms are not disclosed in the public record. What drove Subaru to resolve quickly, and whether any royalty or lump-sum payment changed hands, remains unknown from the available filings.

Dismissed with prejudice: what the joint resolution means for both parties
Dismissal with prejudice is a permanent, merits-equivalent bar
A dismissal with prejudice under federal rules operates as a final judgment on the merits. InfoGation cannot re-file these same claims — across all four patents — against Subaru in any future proceeding. The joint motion signals mutual agreement, distinguishing this from a unilateral withdrawal. The court made no finding of validity or infringement; the substantive merits were never adjudicated.
Claim preclusion appliesInfoGation forfeits future claims but likely extracted value
By agreeing to dismiss with prejudice, InfoGation permanently surrendered its right to sue Subaru again on these four patents. That concession is typically only made in exchange for commercial consideration — a lump-sum payment, licensing royalty, or other arrangement. The public record does not disclose any settlement terms. InfoGation retains the patents and remains free to assert them against other automotive manufacturers.
Settlement consideration likelySubaru secures permanent peace on these four navigation patents
Subaru obtains a durable litigation shield: InfoGation cannot revive these specific claims. The mutual cost-bearing arrangement suggests neither party conceded wrongdoing. Subaru’s STARLINK system can continue operating without the cloud of these particular patent assertions. However, dismissal with prejudice does not confer any ruling on patent validity — the patents remain in force against other defendants.
No validity ruling madeOther automakers remain exposed to InfoGation’s navigation patent portfolio
The swift resolution and absence of invalidity findings means InfoGation’s four navigation patents emerge from this case fully intact and enforceable. Automakers and Tier 1 suppliers with in-vehicle navigation systems — particularly those using similar route guidance, map-matching, or real-time traffic architectures — should treat this case as a signal that InfoGation is actively monetising its portfolio. The STARLINK dispute is consistent with a licensing campaign pattern.

Official order — verbatim text
The joint motion language — ‘the Parties represent that they have resolved all Plaintiff’s claims for relief’ — confirms a complete commercial resolution rather than a partial settlement. The court made no findings on infringement or validity; the dismissal with prejudice is purely procedural, reflecting mutual agreement. The mutual cost-bearing order is standard in privately resolved patent disputes and neither signals weakness by Subaru nor failure by InfoGation. The patents remain valid and enforceable against third parties.
US8406994B1, US6292743B1, US10107628B2 & US8898003B1 — Navigation Systems
The four asserted patents span nearly two decades of navigation system innovation. US6292743B1 (application filed 1999) represents foundational map-matching and position-determination technology. US8406994B1 and US8898003B1 cover dynamic route guidance and navigation interface control architectures, while US10107628B2 — with a 2008 application date and grant extending into the 2030s — covers real-time traffic integration and route optimisation methods. Together they form a layered portfolio targeting core functions present in modern embedded automotive navigation platforms.
The strategic value of this portfolio lies in its breadth across multiple navigation sub-systems, making it difficult for a single defendant to design around all four patents simultaneously. The oldest patent’s priority date predates most modern automotive navigation deployments, potentially capturing a wide range of accused implementations. For Tier 1 navigation suppliers — including those providing systems to Toyota, Honda, Ford, and GM — and for OEMs integrating third-party mapping services, these patents represent a credible assertion risk that warrants proactive FTO analysis.
Should your navigation system be cleared against InfoGation’s patent portfolio?
Any R&D or product team developing or sourcing in-vehicle navigation, route guidance, map-matching, or real-time traffic integration technology should treat InfoGation’s four-patent portfolio as an active enforcement risk. The Subaru STARLINK resolution demonstrates willingness to litigate in EDTX and resolve commercially — a pattern consistent with targeting additional OEMs and Tier 1 suppliers. Pre-launch FTO analysis is particularly urgent for teams integrating third-party navigation stacks into connected-vehicle platforms.

What this case signals for the automotive navigation IP landscape
A four-patent assertion resolved in 112 days in EDTX is a textbook licensing campaign signal for the connected-car sector.
EDTX remains InfoGation’s preferred venue for navigation patent enforcement
Filing in the Eastern District of Texas before Judge Gilstrap — one of the most patent-plaintiff-friendly venues in the US — is a deliberate strategic choice. The rapid resolution suggests Subaru calculated that early settlement was more cost-effective than full EDTX litigation. Automakers without existing clearance on these navigation patents should assess their exposure now.
Four-patent bundles increase settlement pressure on defendants
Asserting four patents simultaneously — spanning multiple application dates from the early 2000s to 2018 — raises the cost and complexity of invalidity challenges. Even if one patent is vulnerable to IPR, the others maintain leverage. This portfolio structuring is a recognised tactic by navigation patent licensors and suggests InfoGation may replicate the approach with other automotive targets.
InfoGation v Subaru — key questions answered
Dismissal with prejudice in this case means InfoGation permanently forfeited its right to re-file these four patent infringement claims against Subaru. The court made no ruling on validity or infringement — the dismissal reflects a private resolution between the parties. The four navigation patents remain valid and enforceable against other defendants.
InfoGation asserted four patents: US8406994B1, US6292743B1, US10107628B2, and US8898003B1. All relate to navigation system technology including map-matching, route guidance, and real-time traffic integration. The accused product was Subaru’s STARLINK Multimedia Navigation system deployed across multiple Subaru vehicle lines.
The 112-day resolution is faster than the typical EDTX patent case lifecycle. The joint nature of the dismissal motion suggests the parties reached a private commercial arrangement early in proceedings. EDTX litigation costs and the complexity of defending against four patents simultaneously likely incentivised Subaru to negotiate rather than contest the case through discovery and trial.
No. The dismissal with prejudice was agreed by both parties and the court made no findings on patent validity or infringement. All four patents — US8406994B1, US6292743B1, US10107628B2, and US8898003B1 — remain presumptively valid and fully enforceable against third parties. Other automotive manufacturers or navigation system suppliers cannot rely on this case as precedent for invalidity arguments.
InfoGation Corporation is a navigation technology IP licensor that holds patents covering core automotive navigation functions. The Subaru assertion is consistent with a portfolio licensing approach targeting OEMs and suppliers whose in-vehicle navigation systems may practice the claimed methods. The rapid resolution pattern suggests InfoGation may pursue additional defendants — R&D and product teams in the automotive navigation space should consider proactive FTO clearance.
