AttestWave v. IBM: Trusted Flow Patent Suit Dismissed With Prejudice
AttestWave, LLC filed suit against IBM in the Eastern District of Texas asserting US7305704B2, a patent covering management of trusted flow systems. After 586 days of litigation, the parties jointly stipulated to dismiss all claims and counterclaims with prejudice, each bearing its own costs and attorney’s fees.
A trusted-flow patent assertion against IBM ends by mutual consent
On April 12, 2023, AttestWave, LLC filed a patent infringement action against International Business Machines Corporation in the Eastern District of Texas (Case No. 4:23-cv-00315), asserting US7305704B2, which covers management of trusted flow systems — a network security architecture governing authenticated data flows. The case was assigned to Judge Sean D. Jordan. AttestWave was represented by Ramey LLP and Spencer Fane LLP; IBM retained Sheppard Mullin Richter & Hampton LLP.
After 586 days of litigation, the parties jointly moved under Federal Rule of Civil Procedure 41(a)(1)(A)(ii) to dismiss all claims and counterclaims with prejudice. The stipulation expressly covers all claims that were or could have been brought in the action, and provides that each party bears its own costs, expenses, and attorney’s fees. The court closed the case on November 18, 2024. A with-prejudice dismissal by joint stipulation is final and bars AttestWave from re-asserting the same claims against IBM in any future action.
The 586-day duration and mutual cost-bearing arrangement suggests the parties likely reached a private resolution — possibly a license, covenant not to sue, or commercial agreement — without requiring a judicial merits ruling. The public record does not disclose any financial terms. What remains unknown is whether any cross-licensing or business arrangement accompanied the stipulation, which is common in NPE-to-large-corporation resolutions of this type.

Dismissed with prejudice: what the joint stipulation means for both parties
FRCP 41(a)(1)(A)(ii) joint stipulation: claims permanently closed
A dismissal under Rule 41(a)(1)(A)(ii) requires the signed agreement of all parties who have appeared. When entered with prejudice, it operates as a final adjudication on the merits for res judicata purposes — AttestWave cannot re-file the same infringement claims against IBM in any US court. Unlike a court-ordered dismissal, no judicial fact-finding is required; the parties control the terms entirely.
Permanent — no re-filing permittedWith prejudice bars future suits on the same patent-defendant pairing
Because the stipulation is with prejudice and covers all claims that were or could have been brought, AttestWave is precluded from asserting US7305704B2 against IBM again. However, the patent itself remains in force and could potentially be asserted against other defendants — the preclusive effect is bilateral, not a ruling on patent validity. IBM does not obtain a finding of non-infringement or invalidity that could be used offensively elsewhere.
Patent validity — unresolved on the meritsMutual cost-bearing suggests negotiated resolution, not capitulation
Each party bearing its own costs, expenses, and attorney’s fees is a neutral cost arrangement typical of negotiated settlements rather than plaintiff or defendant victories. Had IBM prevailed outright, it might have pursued fee recovery under 35 U.S.C. § 285 in an exceptional case finding. The symmetric cost split is consistent with a commercial resolution — possibly including a license or covenant — occurring alongside the stipulation.
No § 285 fee award enteredUS7305704B2 remains a live assertion risk for other network security vendors
The dismissal resolves only the AttestWave–IBM dispute. US7305704B2, covering trusted flow system management, retains its enforceability against other parties. Companies operating in network security, enterprise authentication, or trusted computing architectures should note that no invalidity ruling was entered in this case. AttestWave or any future holder of this patent is free to assert it in fresh proceedings against other defendants.

Official order — verbatim text
The stipulated dismissal invokes Rule 41(a)(1)(A)(ii), requiring mutual consent of all appearing parties, and specifies with-prejudice termination of all claims and counterclaims that were or could have been brought. This language is maximally broad — it forecloses any attempt by AttestWave to re-characterise or re-plead the same grievances. The mutual cost-bearing clause signals a negotiated exit rather than a forced concession by either side, and no judicial finding on infringement, validity, or damages was entered.
US7305704B2 — Management of trusted flow systems
US7305704B2, filed under application number US10/219380, protects methods and systems for managing trusted flow within network environments — governing how authenticated, policy-compliant data flows are established, monitored, and controlled across enterprise infrastructure. The patent sits at the intersection of network security policy enforcement and access control architecture, a domain of growing commercial and regulatory salience as zero-trust network models become mainstream.
For enterprise technology vendors, cloud providers, and security software companies, US7305704B2 represents a meaningful risk vector. Its coverage of trusted flow management touches architectures found in enterprise firewalls, identity-aware proxies, and policy-based network access control products. The absence of any invalidity finding in this litigation means the patent’s claims remain presumptively valid, and any holder could assert it against vendors whose products manage authenticated data paths or enforce trust-based routing policies.
Should you run an FTO analysis against US7305704B2?
Any R&D team building products that manage, authenticate, or enforce policy on network data flows — including zero-trust architectures, identity-aware proxies, network access control platforms, and enterprise security policy engines — should assess their exposure to US7305704B2. The patent’s core claims on trusted flow system management are broad enough to potentially read on widely deployed enterprise security stack components. The IBM litigation resulted in no invalidity ruling, leaving the patent fully enforceable.

What this case signals for the network security IP landscape
A dismissed-with-prejudice NPE suit against IBM in E.D. Texas offers several navigational signals for security vendors and IP teams.
E.D. Texas remains a preferred venue for NPE trusted-flow patent assertions
AttestWave’s choice of the Eastern District of Texas is consistent with broader NPE filing patterns. Security-adjacent patent holders continue to view E.D. Texas favourably for assertion. Companies operating in network authentication and trusted computing should maintain active monitoring of new filings in this district.
No invalidity ruling means US7305704B2 poses residual risk to sector peers
Because the case ended by stipulation without a merits ruling, the validity and scope of US7305704B2 remain untested. Network security vendors — particularly those offering trusted flow, policy enforcement, or authenticated data-path management products — face potential exposure and should assess their FTO position against this patent.
AttestWave v International — key questions answered
The case was dismissed with prejudice by joint stipulation on November 18, 2024, after 586 days of litigation. All claims and counterclaims were terminated under FRCP 41(a)(1)(A)(ii), with each party bearing its own costs and attorney’s fees. No merits ruling on infringement or validity was entered.
AttestWave asserted US7305704B2 (application no. US10/219380), which covers the management of trusted flow systems — a network security patent governing authenticated and policy-compliant data flows across enterprise infrastructure.
No. The joint stipulation dismissed the action without any judicial ruling on patent validity or infringement. US7305704B2 remains presumptively valid and enforceable. The with-prejudice effect is bilateral — it bars AttestWave from suing IBM again on these claims — but does not bind third parties or affect the patent’s enforceability against other defendants.
Symmetric cost allocation — each side bearing its own fees and expenses — is typical of negotiated resolutions rather than outright wins or losses. It suggests the parties likely reached a private commercial arrangement (such as a license or covenant not to sue) alongside the stipulation. The public record does not disclose any financial terms.
AttestWave was represented by Ramey LLP and Spencer Fane LLP, with attorneys Jeffrey E. Kubiak, Kyril Talanov, and William P. Ramey III listed as plaintiff agents. IBM was represented by Sheppard Mullin Richter & Hampton LLP, with attorneys Eric Schlichter, John R. Keville, Michael C. Krill, and Robert Lawrence Green III appearing for the defence.
