IBM v. AttestWave: Federal Circuit Appeal Voluntarily Dismissed in 14 Days
International Business Machines Corp. and AttestWave, LLC jointly agreed to dismiss their Federal Circuit appeal over US7305704B2, a patent covering management of trusted flow systems. The proceeding ended in just 14 days under Fed. R. App. P. 42(b), with each side bearing its own costs — suggesting a negotiated resolution reached swiftly after the appeal was filed.
A 14-day Federal Circuit exit: IBM and AttestWave walk away jointly
Filed on 5 November 2024, Case No. 25-1152 saw IBM — one of the world’s largest patent holders — facing off against AttestWave, LLC at the Court of Appeals for the Federal Circuit in Washington, D.C. The underlying dispute centred on US7305704B2, a patent covering the management of trusted flow systems, a technology domain encompassing secure network identity and access-control flows. IBM was represented by Sheppard Mullin Richter & Hampton LLP, while AttestWave retained Ramey LLP, a firm known for patent assertion work.
The appeal was closed on 19 November 2024 — just 14 days after filing — when the Federal Circuit entered an order dismissing the proceeding under Fed. R. App. P. 42(b) upon the agreement of both parties. Each side was ordered to bear its own costs. The public record does not specify whether the dismissal was with or without prejudice; Rule 42(b) dismissals at the appellate level leave the district court record undisturbed unless otherwise specified, but the terms of any underlying agreement between the parties remain confidential.
A 14-day lifespan is exceptionally brief even by Federal Circuit standards, where voluntary dismissals typically follow the resolution of a licensing negotiation or settlement reached after the appeal was docketed. The mutual cost-bearing arrangement is consistent with a negotiated exit rather than a concession by either party. What drove the resolution — whether a licensing agreement, covenant not to sue, or other commercial arrangement — is not disclosed in the public record. The speed of dismissal suggests the parties may have been in advanced discussions before the appeal was even filed.

Voluntarily dismissed: what the Federal Circuit exit means for both parties
Fed. R. App. P. 42(b): what a joint appellate dismissal means
Rule 42(b) of the Federal Rules of Appellate Procedure allows parties to voluntarily dismiss an appeal by filing a signed agreement or on a party’s motion. Here, both IBM and AttestWave agreed, and the Federal Circuit entered the dismissal by order. Critically, no merits ruling was issued — the court made no finding on patent validity, infringement, or claim scope. The underlying district court record remains as it stood prior to the appeal.
No merits adjudicationWith or without prejudice? The public record is silent
Rule 42(b) dismissals do not automatically specify whether the appeal is dismissed with or without prejudice. The order here simply states the proceeding is dismissed, without expressly addressing preclusion. This distinction matters: a dismissal with prejudice bars re-filing the same claims on appeal; without prejudice may leave options open. The docket does not resolve this question, and any clarifying terms would exist only in a private settlement or agreement between the parties.
Preclusion terms undisclosedIBM exits the appeal without a Federal Circuit ruling on US7305704B2
For IBM, the dismissal means no appellate precedent was set on the validity or enforceability of US7305704B2. The patent’s status remains as it stood after the district court proceedings. IBM avoids the risk of an adverse Federal Circuit ruling that could weaken the patent’s enforceability across its broader portfolio, but also foregoes any affirmance that might have strengthened its licensing position in future disputes.
Patent status unchangedSwift exit suggests resolution — but trusted flow IP remains live
The 14-day dismissal timeline is consistent with a licensing resolution or commercial agreement reached before substantive appellate briefing commenced. For companies operating in the trusted flow management, network identity, or access-control space, US7305704B2 has not been judicially invalidated and remains an enforceable grant. Organisations developing overlapping technology should treat this patent as an active risk and consider FTO analysis accordingly.

Official order — verbatim text
The order’s language — ‘The parties having so agreed’ — confirms this was a bilateral, consensual dismissal rather than a unilateral withdrawal. The Federal Circuit issued no opinion on the merits of the infringement action concerning US7305704B2. Under Fed. R. App. P. 42(b), the court’s role is ministerial once both parties consent; no standard of review was applied and no claim construction or validity analysis appears in the record. The cost-neutrality clause reinforces the reading that neither party conceded liability.
US7305704B2 — Management of Trusted Flow Systems
US7305704B2, filed under application number US10/219380, protects technology directed at the management of trusted flow systems — a domain encompassing mechanisms for establishing, verifying, and controlling trusted data flows within network environments. This patent sits at the intersection of network security, identity management, and access-control architecture. The corrected application number suggests a standard utility patent prosecution path through the USPTO, and the B2 designation confirms it issued with at least one round of post-filing amendment.
For the network security sector, US7305704B2 represents an assertion risk that has survived to the appellate stage without judicial invalidation. IBM’s enforcement of this patent against AttestWave — a smaller assertion entity — suggests the patent may be deployed across a range of targets in the identity and access management space. Competitors and product teams building trusted computing, zero-trust network architecture, or secure flow management solutions should assess whether their implementations risk reading on the claims of this grant, particularly given the absence of any narrowing court order.
Should your team run an FTO against US7305704B2?
Any organisation developing or commercialising technology in the trusted flow management, network identity verification, zero-trust architecture, or access-control domain should treat US7305704B2 as an active clearance risk. The patent has not been invalidated, its claims have not been construed by the Federal Circuit, and the underlying enforcement action was resolved by private agreement. This combination means the full scope of enforceable claims remains uncertain — and potentially broad.

What this case signals for the network security IP landscape
A 14-day Federal Circuit dismissal is rarely accidental — here is what practitioners and product teams should take away.
Speed of dismissal signals pre-existing settlement or licensing deal
Fourteen days is insufficient for substantive appellate briefing. The joint nature of the dismissal and the mutual cost-bearing order together suggest the parties reached a commercial resolution — likely a licensing agreement or covenant not to sue — either immediately before or after the appeal was docketed. Practitioners should note that appeal filings can serve as a pressure mechanism to accelerate settlement.
US7305704B2 has not been invalidated — FTO risk persists
No Federal Circuit ruling on validity or claim scope was issued. The patent covering management of trusted flow systems remains on the register. Companies developing network identity, access-control, or trusted computing products that may read on this patent’s claims should conduct formal FTO analysis before product launch or scaling activity.
