Dynapass IP Holdings v. East West Bancorp — Dismissed With Prejudice
Dynapass IP Holdings LLC filed a patent infringement suit against East West Bancorp and East West Bank in the Eastern District of Texas, asserting a personal communication device authentication patent. The parties jointly moved to dismiss with prejudice after just 109 days, with each side bearing its own costs.
A fast-tracked authentication patent dispute ends bilaterally in East Texas
On 20 February 2023, Dynapass IP Holdings LLC filed a patent infringement action against East West Bancorp, Inc. and its subsidiary East West Bank in the U.S. District Court for the Eastern District of Texas (Case No. 2:23-cv-00065). The suit centred on US6993658B1 (application no. US09/519829), a patent covering the use of personal communication devices for user authentication — technology directly relevant to digital banking access controls.
The case closed on 9 June 2023, just 109 days after filing. The parties filed a Joint Motion to Dismiss representing that they had resolved Plaintiff's claims and requesting dismissal with prejudice. The court granted the motion, dismissing all of Dynapass's claims with prejudice and ordering each party to bear its own costs, expenses, and attorneys' fees. All pending requests for relief not explicitly granted were denied as moot. The recorded basis of termination is Dismissed with Prejudice; the docket order states the parties 'have resolved Plaintiff's claims for relief against Defendants,' though the specific terms of that resolution are not disclosed in the available record.
A resolution within 109 days is notably fast for patent litigation in the Eastern District of Texas, suggesting the parties reached agreement well before any substantive claim construction or merits proceedings. What drove the resolution — whether licensing, design-around, or another commercial arrangement — is not disclosed in the public record. The court retained the lead case as open while closing this member case, indicating this action may form part of a broader multi-defendant campaign by Dynapass.

109 days — from filing to dismissal in E.D. Texas
US6993658B1 — Personal Communication Device User Authentication
Any organisation deploying personal communication devices as part of a user authentication workflow — including mobile banking apps, SMS-based OTP systems, push notification authentication, and device-binding login protocols — should assess exposure to US6993658B1. The patent's claim scope, combined with active enforcement activity by Dynapass in E.D. Texas, makes it a priority for FTO review by financial institutions, fintech platform providers, and enterprise identity solution vendors.
Official order — verbatim text
The court's order grants the parties' Joint Motion to Dismiss in its entirety, dismissing all of Dynapass's claims against both East West Bancorp and East West Bank with prejudice and denying all remaining pending relief as moot. The explicit with-prejudice designation is legally significant: it operates as a final judgment on the merits, permanently barring re-litigation of these specific claims between these parties. The cost-neutrality order — each party to bear its own fees — means no prevailing-party fee award was made under 35 U.S.C. § 285.
Dismissed with prejudice: what the agreed resolution means for both parties
Dismissal with prejudice ends all claims permanently
A dismissal with prejudice is a final adjudication on the merits — Dynapass cannot re-file the same infringement claims against East West Bancorp or East West Bank on US6993658B1 arising from the same conduct. The joint motion was filed by both parties, indicating a mutually agreed exit. The court granted it in full and denied all other pending relief as moot. The specific terms underlying the parties' resolution are not disclosed in the available record.
Claims permanently extinguishedDynapass forecloses future action against these defendants
By agreeing to dismissal with prejudice, Dynapass IP Holdings surrenders the right to pursue East West Bancorp and East West Bank again on these claims. For a patent assertion entity, this typically signals the dispute reached a commercial conclusion acceptable to the plaintiff. However, US6993658B1 remains in force as an asset and the lead case remaining open suggests Dynapass may continue asserting it against other defendants.
Patent remains enforceable elsewhereEast West Bank secures permanent bar on these specific claims
East West Bancorp and East West Bank obtain a permanent bar against Dynapass re-asserting the same US6993658B1 claims arising from the same accused conduct. The cost-sharing order — each party bears its own fees — means no fee-shifting occurred in either direction. The defendants engaged Locke Lord LLP, a firm with substantial patent litigation experience, suggesting they mounted an active defence before resolution was reached.
No fee-shifting orderedAuthentication patent risk remains live for other financial institutions
The rapid resolution and the court's instruction to keep the lead case open suggest this is one action in a wider enforcement campaign around US6993658B1. Banks and fintech companies deploying personal communication devices for user authentication — a near-universal feature in digital banking — should assess their exposure to this patent. The 109-day duration and mutual cost-bearing suggest commercial resolution without a validity or non-infringement finding on the merits.

R&D signals in the personal device authentication patent space
Forward-looking patent and innovation intelligence derived from Dynapass's assertion of US6993658B1 against East West Bank in the digital authentication domain.
Dynapass's authentication patent holdings beyond US6993658B1
Dynapass IP Holdings is a patent assertion entity whose enforcement activity around US6993658B1 suggests a portfolio strategy in personal device authentication. Mapping Dynapass's full patent holdings and related application family members reveals the breadth of potential claim coverage and identifies whether continuation or continuation-in-part applications extend the original priority date into newer authentication architectures.
NPE portfolio mappingFiling trends in device-based user authentication for banking
Personal device authentication — encompassing push notifications, FIDO2/WebAuthn standards, biometric device binding, and OTP protocols — is one of the most actively filed technology spaces in fintech IP. Tracking filing trends by financial institutions, identity platform vendors, and device OEMs in this space reveals where the next generation of enforceable patents is being built and which architectures are currently white space.
Active filing landscapeEast West Bank's own patent activity in digital identity
East West Bancorp's decision to engage Locke Lord LLP with a three-attorney team suggests active defence preparation. Examining East West Bank's own patent filings and any defensive publications in authentication and digital banking reveals whether the institution has built internal IP assets that could support a design-around, cross-licence posture, or invalidity argument in future disputes with assertion entities in this domain.
Defendant defensive IPInnovation gaps adjacent to personal device authentication claims
The claims of US6993658B1 — filed under application US09/519829 — represent early-generation device authentication architecture. Adjacent white-space areas not covered by this patent's priority date include behavioural biometrics, continuous authentication, decentralised identity (DID), and hardware-attested device credentials. Organisations investing in next-generation identity verification can identify patentable ground that lies outside the original claim scope.

What this case signals for the authentication patent IP landscape
A 109-day resolution with no public terms is a hallmark of NPE enforcement strategy — fast pressure, low visibility, and portfolio-level risk for financial services.
US6993658B1 remains enforceable — map your authentication stack now
The dismissal with prejudice is specific to East West Bancorp. Dynapass's lead case remaining open signals continued enforcement activity. Any institution using personal device-based authentication should assess whether their implementation falls within the claims of US6993658B1 before a demand letter arrives.
109-day lifecycle signals pre-litigation commercial resolution pressure
Cases resolved this quickly in E.D. Texas rarely reach claim construction. The mutual cost-bearing order and joint motion suggest Dynapass applied early settlement pressure. Financial institutions without a pre-existing FTO or validity analysis on this patent are exposed to the same playbook.
Dynapass v East — key questions answered
The case was dismissed with prejudice by the Eastern District of Texas on 9 June 2023, 109 days after filing. The court granted the parties' Joint Motion to Dismiss, representing that the parties had resolved Dynapass's claims. Each party was ordered to bear its own costs, expenses, and attorneys' fees. The specific terms of the parties' resolution are not disclosed in the available record.
Dynapass asserted US6993658B1 (application no. US09/519829), a patent covering the use of personal communication devices for user authentication. This technology is relevant to device-based login and identity verification systems widely deployed in digital banking applications.
Dismissal with prejudice operates as a final judgment on the merits, permanently barring Dynapass from re-filing the same infringement claims against East West Bancorp and East West Bank based on the same accused conduct. East West Bank obtained a permanent bar on these specific claims. No fee-shifting was ordered — each party bears its own attorneys' fees.
The court's order in this case directs the Clerk to close this member case while maintaining the lead case as open, which is consistent with a multi-defendant litigation campaign. Other potential defendants in related proceedings cannot be confirmed from this record alone. Monitoring Dynapass's full filing history in PACER and related dockets would reveal the scope of the broader enforcement campaign.
109 days is notably fast for patent litigation in the Eastern District of Texas. The joint motion was filed before any substantive claim construction or merits proceedings are reflected in the record. This timeline is consistent with early-stage commercial resolution, though the specific reasons — licensing, design-around, or other arrangement — are not disclosed in the available public record.
