Patent Armory v. General Nutrition Corp.: Five Call-Routing Patents, 91-Day Dismissal
Patent Armory, Inc. asserted five patents covering intelligent call routing, telephony control, and auction-based entity matching against GNC in the Eastern District of Texas. The case closed after just 91 days when Patent Armory voluntarily dismissed without prejudice — leaving open the possibility of refiling.
A pre-answer dismissal that leaves the door open for GNC
On December 19, 2024, Patent Armory, Inc. filed an infringement action against General Nutrition Corp. (GNC) in the Eastern District of Texas before Judge Rodney Gilstrap, asserting five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The asserted patents cover intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity matching — technologies relevant to customer contact center and CRM infrastructure.
The case resolved on March 20, 2025, when Patent Armory filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because GNC had not yet filed an answer or moved for summary judgment, Patent Armory was entitled to dismiss as of right without court approval. Judge Gilstrap accepted and acknowledged the dismissal, ordered each party to bear its own costs and attorneys’ fees, and directed the clerk to close the case.
The 91-day lifecycle and pre-answer timing suggest the parties may have reached an informal resolution, a licensing arrangement, or that Patent Armory chose to reassess its enforcement strategy — the public record is silent on the underlying rationale. Because the dismissal was without prejudice, Patent Armory retains the right to reassert these patents against GNC in a future action, subject to applicable limitations and any tolling considerations, which remains a material litigation risk for GNC.

Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court approval needed
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without prejudice as of right at any time before the defendant serves an answer or a motion for summary judgment. No court approval is required — the filing of the notice itself effects the dismissal. Judge Gilstrap’s order confirms and acknowledges the dismissal rather than granting it. This procedural posture is notable: it confirms GNC had not yet formally appeared or answered.
Pre-answer voluntary dismissalWithout prejudice vs. with prejudice — the public record is silent on why
A dismissal without prejudice does not resolve the merits and does not bar Patent Armory from refiling the same claims against GNC in the future. A dismissal with prejudice would have extinguished those claims permanently. The court’s order reflects the without-prejudice posture explicitly, but the public docket does not reveal whether a settlement, license, or strategic reassessment drove the decision — the true terms, if any, remain confidential.
Refiling remains possibleGNC faces residual risk — claims not extinguished
Because the dismissal is without prejudice, GNC has not obtained a final judgment in its favour and cannot rely on claim preclusion or res judicata to block a future action on these five patents. GNC should treat this closure as a temporary reprieve rather than a definitive win. If no licensing agreement was reached, monitoring Patent Armory’s future enforcement activity across these patent families is commercially prudent.
No res judicata protectionEach party bears own costs — no fee-shifting ordered
The court’s order that each party bear its own costs, expenses, and attorneys’ fees is the default outcome in a voluntary pre-answer dismissal and does not signal any judicial assessment of the merits or relative strength of either party’s position. Notably, no exceptional-case fee motion under 35 U.S.C. § 285 was triggered, consistent with the case resolving before substantive litigation commenced.

Official order — verbatim text
The court’s order does not adjudicate the merits of Patent Armory’s infringement claims against GNC. The operative language — ‘DISMISSED WITHOUT PREJUDICE’ — confirms that all claims are extinguished procedurally, not substantively. The absence of an answer from GNC and the invocation of Rule 41(a)(1)(A)(i) confirm this was a plaintiff-initiated exit. The cost-bearing order is neutral and does not imply judicial commentary on the strength of either party’s position.
US9456086B1 — Intelligent communication routing system and method
The five asserted patents span two core technology domains: intelligent communication routing (US9456086B1, US10491748B1, US7269253B1, US7023979B1, US10237420B1) and auction-based entity matching for call routing. These patents cover methods and systems for dynamically routing inbound telephone calls, controlling telephony infrastructure with intelligence-layer logic, and matching callers to agents or services via auction-style allocation. Application dates range from early-2000s filings through mid-2010s continuations, suggesting a long-lived and iteratively extended patent family.
For the retail and consumer-services sector, these patents are strategically significant because virtually every large retailer operates customer contact centres, IVR systems, or third-party call-routing platforms that could fall within the claimed scope. The breadth of the portfolio — spanning both method and system claims across five patents — increases the difficulty of designing around any single claim. Companies licensing call-centre software or deploying cloud-based communication platforms should review vendor indemnification provisions and assess whether their technology stack intersects with these claim families.
Should you run an FTO against US9456086B1 and the Patent Armory call-routing portfolio?
Any business operating customer contact centres, IVR routing systems, or intelligent call-distribution platforms — particularly in retail, health, and consumer services — should assess FTO exposure against these five patents. GNC’s position as a specialty retailer with significant inbound call volume illustrates the defendant profile targeted. If your organisation relies on third-party telephony vendors, confirm whether vendor agreements include IP indemnification covering these patent families.
PatSnap Eureka’s FTO Search Agent can map each of these five patent numbers against your product architecture, flag relevant claim elements, and surface related prior art that may bear on validity. Eureka can also monitor Patent Armory’s enforcement portfolio for new continuations, assignments, or litigation filings — giving your IP team early warning before a complaint is served.

What this case signals for the call-routing and contact-centre IP landscape
A five-patent assertion by a licensing entity against a major retail chain, withdrawn before the defendant answered — a pattern worth tracking.
Pre-answer dismissals in E.D. Texas often signal confidential licensing activity
When a plaintiff voluntarily dismisses without prejudice before the defendant answers, it typically signals either a negotiated resolution or a tactical repositioning. In patent licensing campaigns, this outcome often reflects a licence being granted. Companies in GNC’s sector receiving similar pre-answer complaints should treat early engagement seriously.
Five-patent portfolios targeting telephony infrastructure are a recurring enforcement model
Patent Armory’s assertion of five patents spanning intelligent call routing, auction-based entity matching, and telephony control suggests a broad portfolio sweep rather than a single-patent assertion. Retailers and consumer-facing businesses relying on call-centre or IVR infrastructure should audit their vendor agreements and assess FTO exposure across these patent families.
Patent v General — key questions answered
Patent Armory filed an infringement action against GNC on December 19, 2024 in the Eastern District of Texas, asserting five patents covering intelligent call routing and telephony systems. Patent Armory voluntarily dismissed the case without prejudice on March 20, 2025, before GNC had answered the complaint. Each party was ordered to bear its own costs and attorneys’ fees.
Patent Armory asserted five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The patents cover intelligent communication routing systems and methods, telephony control systems with intelligent call routing, and auction-based entity matching systems — technologies relevant to customer contact centre and IVR infrastructure.
A dismissal without prejudice means the case is closed but the claims are not permanently extinguished. Patent Armory retains the right to refile the same infringement claims against GNC in the future. GNC did not obtain a final judgment on the merits, so it cannot invoke claim preclusion to block a future action. The dismissal does not constitute an admission of non-infringement by either party.
The public record does not disclose the reason for the pre-answer dismissal. Common explanations in comparable cases include a negotiated patent licence, an informal settlement, or a decision to reassess enforcement strategy. The without-prejudice posture and the parties bearing their own costs are consistent with either an undisclosed licensing resolution or a tactical pause in enforcement activity.
