AttestWave LLC v. SAP America: Secure Logic Interlocking Patent Dismissed With Prejudice
AttestWave LLC filed a patent infringement action against SAP America, Inc. in the Delaware District Court, asserting US7895643B2 covering secure logic interlocking technology. The case ended in a voluntary dismissal with prejudice after just 113 days, before SAP filed an answer, with each party absorbing its own legal costs.
Pre-answer dismissal with prejudice signals rapid resolution in SAP infringement dispute
AttestWave LLC initiated this patent infringement action against SAP America, Inc. on 5 March 2025 in the U.S. District Court for the District of Delaware, before Judge Richard G. Andrews. The sole patent asserted was US7895643B2, directed to secure logic interlocking technology, a domain relevant to enterprise authentication and access-control architectures of the kind SAP deploys across its software ecosystem.
The case closed on 26 June 2025 — just 113 days after filing — when AttestWave invoked Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure to voluntarily dismiss all claims with prejudice. Because SAP had not yet filed an answer or a motion for summary judgment, AttestWave was entitled to dismiss as of right. Critically, the dismissal was expressly with prejudice, meaning AttestWave permanently relinquished its right to reassert these claims against SAP on this patent.
The compressed timeline and mutual cost-bearing arrangement suggest the parties likely reached a private resolution — whether a license, covenant not to sue, or commercial agreement — before litigation could develop substantive traction. The public record is silent on any financial terms. From a docket perspective, no claim construction, discovery, or dispositive motion activity was recorded, leaving the validity and scope of US7895643B2 entirely untested by the court.

113 days — resolved before answer or summary judgment motion was filed
Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): voluntary dismissal as of right
Because SAP had not yet filed an answer or motion for summary judgment, AttestWave could dismiss unilaterally without court approval under Rule 41(a)(1)(A)(i). The plaintiff elected to make that dismissal with prejudice — a stronger concession than the rule requires — permanently extinguishing all asserted claims against SAP on US7895643B2. This election is typically a negotiated term, not a unilateral litigation decision.
Rule 41(a)(1)(A)(i) — with prejudiceAttestWave permanently barred from re-suing SAP on this patent
A with-prejudice dismissal operates as a final adjudication on the merits for res judicata purposes. AttestWave cannot refile the same infringement claims against SAP under US7895643B2 in any court. If a private settlement was reached, AttestWave likely received consideration that made surrendering future litigation rights commercially acceptable. The patent itself remains enforceable against third parties.
No re-filing against SAPSAP exits with prejudice — and without paying legal costs
SAP America achieved a clean exit: all claims dismissed with prejudice and no adverse costs order. Having never filed an answer, SAP faces no estoppel or adverse finding on the patent’s validity or infringement. The cost-neutrality clause — each party bears its own fees — is consistent with a negotiated resolution rather than a capitulation, though the record does not confirm any payment direction.
Claims extinguished, costs neutralUS7895643B2 remains live against the broader enterprise software market
The dismissal resolves only the AttestWave–SAP dispute. US7895643B2 is unencumbered by any validity ruling, claim construction, or judicial finding. Competitors in the secure authentication and enterprise access-control space — and particularly other large ERP and identity management vendors — remain exposed to assertion risk under this patent. The rapid pre-answer resolution suggests the patent may carry meaningful licensing leverage.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i), confirming SAP had filed neither an answer nor a summary judgment motion at the time of dismissal. The express election of ‘with prejudice’ is the legally significant phrase: it converts a procedural exit into a final adjudication on the merits, permanently barring AttestWave from reasserting these specific claims against SAP. The mutual cost-bearing clause — departing from the default American rule — suggests both parties agreed to this allocation as part of a broader resolution, rather than it arising from a judicial fee award.
US7895643B2 — Secure Logic Interlocking Technology
US7895643B2, filed under application number US10/219378, covers secure logic interlocking technology — a class of inventions directed at controlling and authenticating access through interlocked logical security mechanisms. This technical domain intersects with enterprise identity management, privileged access control, and software-layer authentication architectures. The patent’s issued status and B2 designation confirm it has completed examination and any post-grant correction process, giving it presumptive validity under 35 U.S.C. § 282.
For large enterprise software vendors — particularly those offering ERP, identity management, or cloud-based access-control platforms — secure logic interlocking patents represent a recurring assertion risk. SAP’s broad product surface across authentication workflows makes it a natural assertion target. The fact that AttestWave resolved this dispute privately and rapidly, without testing the patent’s claims in court, suggests the patent carries credible licensing leverage. Competitors in adjacent enterprise security software segments should assess their exposure before receiving a demand letter.
Should your team run an FTO against US7895643B2?
Any enterprise software vendor, identity management provider, or access-control platform developer operating in the secure authentication space should evaluate potential overlap with US7895643B2. The patent’s secure logic interlocking claims — untested by any court — remain fully enforceable. R&D teams designing privileged access management, zero-trust architectures, or software-defined access-control layers are the most directly exposed. A freedom-to-operate analysis is particularly urgent for companies that have received communications from AttestWave or are expanding into authentication-adjacent product lines.

What this case signals for the enterprise software IP landscape
A 113-day with-prejudice exit, before any answer, is a classic signal of a private resolution — and a warning for competitors still in the patent’s crosshairs.
Pre-answer dismissals with prejudice almost always reflect private resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant even answers, it typically signals a negotiated outcome — license, covenant, or commercial agreement. AttestWave received no public adverse ruling and SAP paid no disclosed costs, consistent with a quiet settlement. IP teams at similarly sized enterprise software vendors should treat this pattern as a signal that the patent holder is active and resolving disputes efficiently.
US7895643B2 has never been claim-construed or validity-tested in court
Because the case ended before any substantive proceedings, the claims of US7895643B2 remain judicially untested. Any third party now facing assertion from AttestWave cannot rely on prior adverse findings against the patent. An independent validity and claim-scope analysis is essential before any design-around or non-infringement position is adopted. The patent’s secure logic interlocking claims should be reviewed against current enterprise authentication architectures.
AttestWave v SAP — key questions answered
A dismissal with prejudice under Rule 41 operates as a final adjudication on the merits. AttestWave is permanently barred from refiling the same infringement claims against SAP America under US7895643B2 in any federal court. The patent remains enforceable against other defendants not party to this dismissal.
AttestWave asserted a single patent: US7895643B2, covering secure logic interlocking technology. The application number on record is US10/219378. The patent carries presumptive validity and its claims were not construed or adjudicated during the 113-day litigation.
Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss as of right before the defendant files an answer or motion for summary judgment. AttestWave exercised this right 113 days after filing. The with-prejudice designation and mutual cost-bearing clause suggest the parties had reached a private resolution by that point, though no terms are disclosed in the public record.
No. The dismissal produced no ruling on validity, infringement, or claim scope. US7895643B2 retains its presumptive validity under 35 U.S.C. § 282. Third parties cannot rely on any adverse judicial finding against the patent arising from this case, because no such finding was made.
The dismissal notice expressly states each party shall bear its own costs, expenses, and attorneys’ fees. No fee-shifting award was made. This mutual cost-bearing arrangement is consistent with a negotiated exit rather than a unilateral capitulation, though the public record does not confirm whether any financial consideration changed hands privately.
