Stragent v. Volvo Car USA: Federal Circuit Appeal Voluntarily Dismissed
Stragent, LLC appealed against Volvo Car USA, LLC at the Federal Circuit over four patents covering AUTOSAR automotive software architecture. The parties jointly agreed to dismiss the appeal under Fed. R. App. P. 42(b) after 139 days, with each side bearing its own costs.
Four AUTOSAR patents, one Federal Circuit exit — by agreement
Stragent, LLC filed this Federal Circuit appeal on 7 May 2024, challenging an outcome in an underlying AUTOSAR patent infringement action against Volvo Car USA, LLC. The four patents at issue — US10002036B2, US9705765B2, US10031790B1, and US10248477B2 — all relate to AUTOSAR, the standardised automotive open system architecture widely adopted across the automotive software stack.
The appeal concluded on 23 September 2024 when the parties filed a joint agreement to dismiss under Federal Rule of Appellate Procedure 42(b). The court ordered dismissal accordingly and directed each side to bear its own costs. Crucially, the public record does not specify whether the dismissal was with or without prejudice, leaving the question of future re-litigation open from a documentary standpoint.
The 139-day lifespan of this appeal is notably short, even by Federal Circuit standards, suggesting the parties may have reached a commercial resolution — or simply elected not to pursue the appeal further — relatively soon after filing. Whether a settlement underlies the mutual dismissal, or one party simply withdrew, cannot be confirmed from the public docket. The cost-neutrality of the order is consistent with a negotiated exit rather than a unilateral abandonment.

Voluntarily dismissed: what the mutual exit means for both parties
Fed. R. App. P. 42(b): dismissal by party agreement
Rule 42(b) allows parties to a Federal Circuit appeal to dismiss voluntarily by filing a signed agreement. No merits ruling is issued — the appellate court neither affirms nor reverses the decision below. The procedural posture of the underlying district court case therefore remains as it stood before the appeal, and the Federal Circuit made no finding on the AUTOSAR patent claims.
No merits adjudicationWith or without prejudice? The record is silent
A voluntary dismissal may be with prejudice — permanently barring re-litigation — or without prejudice, preserving the right to refile. The order in this case does not specify. That distinction matters significantly: if without prejudice, Stragent may potentially reassert these AUTOSAR patents in future proceedings. If with prejudice, the claims are extinguished. Practitioners should not assume either outcome from the public record alone.
Prejudice terms undisclosedStragent exits the appeal without a Federal Circuit ruling
As appellant, Stragent initiated this Federal Circuit appeal and then joined the agreement to dismiss it. Without a merits ruling, Stragent receives no appellate vindication of its AUTOSAR patent positions. Whether this reflects a settlement, a strategic recalibration, or licensing resolution is not apparent from the public docket. The cost-neutral order suggests a negotiated rather than one-sided exit.
No appellate vindicationVolvo Car USA avoids Federal Circuit merits ruling
Volvo Car USA avoids any Federal Circuit pronouncement on the validity or infringement of the four AUTOSAR patents. The cost-neutrality of the dismissal order is consistent with a negotiated resolution. However, without a with-prejudice finding or an invalidity ruling, the AUTOSAR patent portfolio asserted by Stragent may remain a latent risk for Volvo and similarly situated automotive OEMs using AUTOSAR-compliant systems.

Official order — verbatim text
The order’s language — ‘The parties having so agreed’ — confirms this was a bilateral, consensual dismissal rather than a court-initiated termination. Invocation of Fed. R. App. P. 42(b) means the Federal Circuit issued no opinion on the merits of the AUTOSAR patent claims. The cost-neutrality provision (‘each side shall bear their own costs’) is a standard feature of negotiated exits and does not indicate relative litigation strength. No inference about patent validity or infringement should be drawn from this procedural outcome.
US10002036B2 and three related AUTOSAR software architecture patents
The four patents — US10002036B2, US9705765B2, US10031790B1, and US10248477B2 — originate from application families filed in 2017 and 2018, targeting software architecture methods consistent with the AUTOSAR standard. AUTOSAR defines a layered software architecture for automotive ECUs, governing how software components communicate, how run-time environments are structured, and how applications interface with underlying hardware abstraction layers. Patents in this space typically claim specific communication, scheduling, or component-binding methods within that architecture.
The strategic significance of this portfolio lies in AUTOSAR’s near-universal adoption across automotive OEMs and Tier 1 suppliers. Any entity holding enforceable patents on AUTOSAR-compliant implementation methods is positioned to assert against a broad defendant class. With the shift to software-defined vehicles accelerating adoption of AUTOSAR Adaptive Platform, the relevance of patents claiming software architecture methods is likely to grow, making clearance analysis against this portfolio commercially material for any automotive software programme.
Should your AUTOSAR implementation be cleared against US10002036B2?
Any R&D team, OEM, Tier 1 supplier, or automotive software vendor implementing AUTOSAR Classic or Adaptive Platform should assess exposure against these four patents. The fact that an appeal reached the Federal Circuit before mutual dismissal — without a validity or non-infringement ruling — means no court has held these patents unenforceable. Product teams building ECU software, run-time environments, or inter-component communication layers on AUTOSAR should treat this portfolio as an active clearance item.
PatSnap Eureka’s FTO Search Agent can map US10002036B2, US9705765B2, US10031790B1, and US10248477B2 against your specific AUTOSAR implementation stack, identify claim elements most relevant to your architecture, surface prior art that may support invalidity arguments, and flag continuation applications from the same priority families. This gives IP counsel and engineering leads a structured, evidence-based clearance baseline rather than a manual claim-by-claim review.

What this case signals for the automotive software IP landscape
Four AUTOSAR patents reaching the Federal Circuit — then quietly exiting — carries implications for every OEM and Tier 1 supplier building on the AUTOSAR standard.
AUTOSAR standardisation does not confer immunity from patent claims
The assertion of four patents against an AUTOSAR implementation by a major OEM illustrates that industry-standard adoption does not neutralise patent risk. Automotive software teams implementing AUTOSAR — including Classic and Adaptive profiles — should maintain active FTO monitoring against the Stragent portfolio and comparable assertion entities.
Voluntary dismissal without prejudice disclosure leaves exposure open
The public record’s silence on prejudice terms means Volvo and other AUTOSAR implementers cannot assume this threat has been permanently resolved. IP counsel at OEMs and Tier 1 suppliers should track the Stragent portfolio — US10002036B2, US9705765B2, US10031790B1, US10248477B2 — for continuation filings or re-assertion activity.
Stragent v Volvo — key questions answered
The Federal Circuit appeal was voluntarily dismissed by agreement of both parties under Fed. R. App. P. 42(b) on 23 September 2024, 139 days after filing. No merits ruling was issued on the four AUTOSAR patents. Each side bore its own costs.
Stragent asserted four patents: US10002036B2, US9705765B2, US10031790B1, and US10248477B2. All relate to AUTOSAR automotive open system architecture software methods, filed across application families in 2017 and 2018.
The dismissal order does not specify. The public record is silent on whether the dismissal was with or without prejudice. Practitioners should not assume either outcome without reviewing any underlying settlement agreement, which has not been made public.
A Rule 42(b) dismissal means the Federal Circuit issued no opinion on the validity, enforceability, or infringement of the asserted AUTOSAR patents. The patents remain in force unless separately challenged via IPR or other invalidity proceedings. The underlying district court record stands as it was before the appeal.
Indirectly, yes. Because no Federal Circuit invalidity or non-infringement ruling was issued, other OEMs and Tier 1 suppliers implementing AUTOSAR cannot rely on this case as precedent clearing the Stragent portfolio. The four patents remain potentially enforceable against other AUTOSAR implementers, and continuation risk from the same priority families persists.
