Patent Armory Inc v. Wrike Inc: Voluntary Dismissal After 61 Days
Patent Armory Inc filed suit against project management platform Wrike Inc in the Northern District of Texas, asserting two patents covering entity-matching auction methods and intelligent telephony call routing. The case closed just 61 days after filing when Patent Armory voluntarily dismissed without prejudice under Rule 41(a)(1)(A)(i).
Pre-answer dismissal in a two-patent software infringement case
On 11 June 2025, Patent Armory Inc filed a patent infringement action against Wrike Inc — a cloud-based project management and work collaboration platform — before Judge Ada Brown in the Northern District of Texas (Case No. 3:25-cv-01491). Patent Armory asserted two US patents: US9456086B1, directed to a method and system for matching entities in an auction, and US7023979B1, covering a telephony control system with intelligent call routing. Plaintiff was represented by DNL Zito and Rabicoff Law LLC; Wrike engaged DLA Piper US LLP.
The case closed on 11 August 2025 — just 61 days after filing — when Patent Armory filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Crucially, Wrike had not yet filed an answer or moved for summary judgment, meaning no court approval was required and the dismissal took effect immediately upon filing. The case was dismissed without prejudice, preserving Patent Armory’s right to refile the same claims.
A 61-day lifespan before any substantive response from the defendant is notably brief and typically suggests early-stage resolution — whether through licensing negotiations, a settlement, or a decision by plaintiff to reassess claim viability. The public record is silent on whether any commercial agreement accompanied the dismissal. Because the dismissal is without prejudice, Wrike faces residual exposure to refiling, particularly if Patent Armory views the litigation as a negotiating instrument.

61 days — resolved before defendant answered or moved for summary judgment
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): unilateral right to dismiss
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant has served an answer or a motion for summary judgment. The dismissal is self-executing — it takes effect the moment the notice is filed. Here, Wrike had not yet responded, so Patent Armory exercised this right unilaterally with no judicial scrutiny of the merits.
No court approval requiredWithout prejudice: refiling remains possible
A dismissal without prejudice does not extinguish the underlying claims — Patent Armory retains the legal right to refile against Wrike on the same patents. By contrast, a dismissal with prejudice would permanently bar re-assertion. The public record here confirms ‘without prejudice’ but does not disclose whether any side agreement, licence, or payment conditions the dismissal. That distinction matters materially for Wrike’s forward-looking IP exposure.
Refiling right preservedPatent Armory exits with optionality intact
By dismissing without prejudice before Wrike responded, Patent Armory avoids any adverse ruling on claim construction, invalidity, or non-infringement. The patents remain asserted and unadjudicated. This exit posture is consistent with a plaintiff who either reached an off-record resolution or is preserving leverage for future enforcement — potentially against Wrike or other defendants in the same technology space.
Claims unadjudicatedWrike escapes adjudication but not long-term risk
Wrike avoids a merits ruling and any injunction or damages award in this proceeding. However, the without-prejudice dismissal means the threat is not extinguished. If no licence was granted, Wrike remains exposed to future litigation on US9456086B1 and US7023979B1. Companies in this position often evaluate IPR petitions at the USPTO or seek covenant-not-to-sue protections to reduce residual exposure.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly confirms the without-prejudice designation, while noting Wrike had not answered or moved for summary judgment. This procedural posture means no substantive ruling was made on infringement, validity, or claim construction. The explicit ‘without prejudice’ language in the filing is legally significant: it preserves Patent Armory’s right to refile, and the absence of any reciprocal filing by Wrike suggests no formal invalidity counterclaim was lodged before exit.
US9456086B1 & US7023979B1 — Auction Matching and Telephony Routing
US9456086B1 (application no. US12/719827) claims a method and system for matching entities in an auction context — technology relevant to algorithmic matching, resource allocation, and bidding frameworks deployed in software platforms. US7023979B1 (application no. US10/385389) covers a telephony control system with intelligent call routing, a domain relevant to VoIP, unified communications, and call management integrations embedded in enterprise SaaS products. Both patents were asserted as utility patents in a direct infringement action.
The strategic breadth of these patents is notable: US9456086B1’s auction-matching logic could potentially read on a range of SaaS workflow and resource-allocation features beyond traditional marketplaces, while US7023979B1’s telephony routing claims are relevant to any enterprise platform incorporating communications features. Patent Armory’s decision to assert both patents against a project management platform like Wrike suggests a theory of infringement tied to Wrike’s integration or automation capabilities. The without-prejudice dismissal leaves both patents available for future enforcement actions.
Should your SaaS product run an FTO against US9456086B1 and US7023979B1?
Any R&D or product team building algorithmic matching, workflow automation, auction-adjacent pricing features, or telephony/VoIP integrations into an enterprise SaaS platform should treat these patents as live enforcement risk. The without-prejudice dismissal against Wrike means Patent Armory retains full enforcement rights, and the filing itself signals active monetisation intent. Product counsel and engineering leads should map independent claims against current feature sets before launch or feature expansion.

Patent Armory’s exit strategy suggests assertion-first, negotiate-second playbook
Filing suit and voluntarily dismissing before the defendant responds is a pattern associated with patent monetisation entities seeking licensing revenue rather than litigation outcomes. SaaS platforms receiving demand letters or complaints from similar plaintiffs should assess the asserted patents early and engage licensing counsel promptly, as the window before a Rule 41 exit is often the negotiation period.
N.D. Texas remains a preferred venue for PAE-style filings against tech defendants
The Northern District of Texas continues to attract patent assertion entity filings against software and SaaS companies. Judge Ada Brown’s docket includes a range of technology infringement matters. Companies with significant SaaS operations should maintain active docket monitoring for this district and have pre-vetted outside counsel available for rapid pre-answer response.
Patent v Wrike — key questions answered
Patent Armory Inc filed a patent infringement suit against Wrike Inc in the Northern District of Texas on 11 June 2025, asserting US9456086B1 and US7023979B1. The case was voluntarily dismissed without prejudice by Patent Armory on 11 August 2025 — 61 days after filing — before Wrike had answered or moved for summary judgment.
A without-prejudice dismissal does not extinguish Patent Armory’s claims. Wrike remains exposed to a refiled lawsuit on the same two patents unless a licence or covenant-not-to-sue was obtained. The public record does not disclose any settlement terms, so Wrike’s residual risk cannot be assessed from the docket alone.
US9456086B1 claims a method and system for matching entities in an auction. Its assertion against a project management SaaS platform like Wrike suggests Patent Armory’s counsel identified matching, allocation, or bidding-adjacent logic in Wrike’s product. The case was dismissed before any claim construction ruling clarified the patent’s scope.
US7023979B1 covers a telephony control system with intelligent call routing. It is relevant to enterprise SaaS platforms that incorporate VoIP, unified communications, or call management features. Its assertion against Wrike may relate to telephony integrations within Wrike’s collaboration ecosystem.
A rapid voluntary dismissal under Rule 41(a)(1)(A)(i) — before the defendant answers — typically indicates that the litigation served as a negotiating instrument. The plaintiff may have secured a licence or payment, or may have decided to reassess infringement theories. Because no merits ruling is required, the exit is low-cost for the plaintiff while preserving all enforcement rights for future action.
