Case overview

CloudGuard Infringement Suit Ends at Plaintiff's Initiative

Sulaco Enterprises LLC filed this infringement action on 5 December 2025 in the Eastern District of Texas before Judge Rodney Gilstrap, asserting US8990942B2 against Check Point Software Technologies, Inc. The accused products span Check Point's CloudGuard suite, including CloudGuard CDR, CNAPP, Code Security, Network Security, Posture Management, WAF, Wiz, and Workload, as well as Developer Security and Quantum Network Products.

The recorded basis of termination is 'Dismissed with Prejudice.' The docket order states that Plaintiff Sulaco filed a Notice of Voluntary Dismissal with Prejudice, which the Court accepted, dismissing all of Plaintiff's claims against Defendant with prejudice. The Court further ordered that the parties bear their own costs and attorneys' fees, and denied all pending requests for relief as moot.

Resolution in 122 days — before any substantive merits ruling is on record — suggests the matter concluded at plaintiff's initiative and without publicly disclosed negotiated terms. What drove Sulaco's decision to dismiss with prejudice at this stage, and whether any collateral arrangement exists between the parties, is not disclosed in the available public record.

Should you run an FTO against US8990942B2?

Any company developing or commercialising cloud-native application protection platforms, network security gateways, web application firewalls, or cloud posture management tools should treat US8990942B2 as an active risk. The breadth of Check Point products named in this suit — from CDR to developer security — suggests the patent may be read broadly across cloud-security architectures. No court has construed or narrowed its claims.

Official verdict

Official order — verbatim text

Before the Court is the Notice of Voluntary Dismissal with Prejudice (the “Notice”) filed by Plaintiff Sulaco Enterprises LLC (“Plaintiff”). (Dkt. No. 10). In the Notice, Plaintiff states that it dismisses its case against Defendant Check Point Software Technologies Ltd. (“Defendant”) with prejudice. (Id. at 1). Having considered the Notice, the Court ACCEPTS AND ACKNOWLEDGES that all Plaintiff’s claims against Defendant in the above-captioned case are DISMISSED WITH PREJUDICE. The parties are to bear their own costs and attorneys’ fees. All pending requests for relief asserted by the parties in the case not explicitly granted herein are DENIED AS MOOT. The Clerk of Court is directed to CLOSE the above-captioned case because no parties or disputes remain.
Source: PACER Docket, Case 2:25-cv-01192, Texas Eastern District Court

The court's order reflects acceptance of a plaintiff-initiated voluntary dismissal with prejudice under the notice procedure, resulting in no merits adjudication on infringement, validity, or claim scope. The own-costs ruling is neutral — neither party was awarded fees — and all pending motions were denied as moot, leaving the substantive questions raised by the complaint entirely unresolved on the record.

Dismissal terms

Dismissed with prejudice: what the voluntary dismissal means for both parties

Legal mechanism

Voluntary dismissal with prejudice bars all future claims on US8990942B2

A Rule 41 dismissal with prejudice is a final adjudication on the merits for claim-preclusion purposes. By filing the Notice and having it accepted by the court, Sulaco permanently surrendered its right to re-assert these specific infringement claims against Check Point. The dismissal order also denied all pending relief as moot and directed the clerk to close the case.

Claim-preclusive dismissal
Patent holder outcome

Sulaco forfeits right to re-sue Check Point on this patent

Dismissal with prejudice means Sulaco Enterprises cannot refile this action or relitigate the same infringement claims against Check Point Software on US8990942B2. The patent itself remains in force, and Sulaco may still assert it against third parties, but Check Point gains substantial protection from this specific litigation record.

No re-filing against defendant
Defendant outcome

Check Point secures a preclusive bar without a merits ruling

Check Point Software achieves closure on this action without any admission of infringement or a finding on the validity or scope of US8990942B2. The with-prejudice dismissal and the own-costs order mean Check Point avoids both ongoing litigation exposure and fee-shifting risk. No defendant agents appear on record, consistent with early resolution.

No liability finding
Commercial implications

CloudGuard suite cleared of record — but patent remains live

US8990942B2 survives this litigation unscathed in terms of validity — no IPR, no invalidity ruling, no claim construction occurred. Other CloudGuard competitors or cloud-security vendors operating in adjacent spaces should note that Sulaco retains the patent and may assert it elsewhere. The early dismissal leaves the patent's enforceability posture and commercial reach unresolved by any court.

R&D signals

R&D signals in the cloud security and CNAPP patent space

Forward-looking patent and innovation intelligence derived from the Sulaco v. Check Point action — relevant to cloud-security vendors, CNAPP developers, and network-security R&D teams.

Patent portfolio

Sulaco Enterprises' cybersecurity patent filing activity

Sulaco Enterprises LLC's assertion of US8990942B2 against a major cloud-security vendor suggests a focused patent portfolio in the cybersecurity domain. Mapping Sulaco's full portfolio — including continuations, divisionals, and related applications — can reveal whether additional patents are positioned for assertion against cloud-security, CNAPP, or network-protection products.

PAE portfolio monitoring
Technology landscape

Filing trends in cloud-native application protection (CNAPP)

The CNAPP and cloud posture management space is attracting growing patent activity from both operating companies and assertion entities. Tracking filing trends around cloud workload protection, CDR, and WAF technologies can identify emerging whitespace and crowded claim areas before products ship — reducing downstream assertion risk from patents like US8990942B2.

CNAPP IP landscape
Defendant IP posture

Check Point Software's defensive patent position in cloud security

Check Point Software is one of the largest cybersecurity IP holders globally. Analysing Check Point's own patent portfolio in cloud posture management, network security, and WAF domains reveals its defensive moat and any cross-licensing leverage it could deploy in future assertion scenarios. Their Quantum and CloudGuard filing clusters are particularly relevant.

Defensive portfolio analysis
White space

Adjacent innovation gaps near US8990942B2's claim space

With US8990942B2's claims never construed by a court, the boundaries of its coverage remain commercially undefined. Performing a prior-art landscape and white-space analysis around its application date (US13/893943) can surface unclaimed adjacent areas in cloud-security architecture — representing R&D filing opportunities or freedom-to-operate corridors for competing vendors.

Strategic implications

What this case signals for the cloud security IP landscape

A rapid with-prejudice dismissal in E.D. Texas leaves Check Point cleared but the patent live — signalling continued assertion risk for cloud-security vendors.

With-prejudice dismissal protects Check Point but not the broader market

The claim-preclusive dismissal shields Check Point specifically. However, US8990942B2 remains active and unlitigated on the merits. Competing cloud-security and CNAPP vendors should assess whether their product architectures share the technical characteristics targeted in this suit.

E.D. Texas and Judge Gilstrap remain a venue risk for cybersecurity defendants

Sulaco's choice of the Eastern District of Texas under Judge Gilstrap is consistent with established plaintiff-friendly venue strategy for patent assertion entities. Cloud-security companies without a Texas nexus should monitor assertion patterns here and ensure venue-transfer options are preserved from day one.
