Patent Armory v. Stewart Title Guaranty: 5-Patent Call Routing Suit Dropped in 75 Days
Patent Armory, Inc. asserted five patents covering intelligent call routing, telephony control, and auction-based entity matching against Stewart Title Guaranty Co. in the Southern District of Texas. The plaintiff voluntarily dismissed the action without prejudice after just 75 days, leaving all five patents available for future assertion.
Five-patent call routing assertion against a title insurer ends at 75 days
On 28 November 2023, Patent Armory, Inc. filed suit against Stewart Title Guaranty Co. in the U.S. District Court for the Southern District of Texas (Case No. 4:23-cv-04470), assigned to Chief Judge Lee H. Rosenthal. The complaint asserted five U.S. patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — collectively covering intelligent communication routing systems, telephony control with smart call routing, and method-and-system frameworks for matching entities in an auction context.
The case closed on 11 February 2024, a mere 75 days after filing, when the court entered dismissal without prejudice pursuant to the plaintiff’s own notice of dismissal (Docket Entry No. 12). A dismissal without prejudice means the litigation was terminated on procedural rather than substantive grounds: no court ruled on the merits of infringement or validity, and Patent Armory is legally free to refile the same claims against Stewart Title Guaranty or any other defendant in the future.
The speed of resolution — before any answer, claim construction, or dispositive motion — is consistent with early settlement negotiations, a licensing agreement reached off the record, or a strategic decision by Patent Armory to redirect its enforcement resources. The public record is silent on whether consideration changed hands. Because no final judgment was entered, neither party received a substantive ruling, and Stewart Title Guaranty has not secured any preclusive defence against these patents.
Filing to voluntary dismissal in 75 days
Resolved in under 11 weeks — well before any substantive court ruling
Dismissed without prejudice — what the order means for both parties
Plaintiff-initiated voluntary dismissal under FRCP 41(a)
A notice of dismissal filed before the defendant serves an answer or motion for summary judgment is self-executing under Federal Rule of Civil Procedure 41(a)(1)(A)(i) — the court’s role is merely confirmatory. Here, Docket Entry 12 was the plaintiff’s own notice, indicating the case ended at Patent Armory’s election, not by any court ruling on the merits or defendant’s motion.
FRCP 41(a) voluntary dismissalWithout prejudice: the door stays open for Patent Armory
A dismissal without prejudice does not extinguish the underlying claims. Patent Armory retains the right to assert the same five patents against Stewart Title Guaranty again, or against other defendants in the title insurance and real estate technology sector. Stewart Title Guaranty has secured no invalidity ruling, no non-infringement finding, and no preclusive judgment from this proceeding.
No preclusive effect on patent rights75-day window: resolution before any substantive litigation step
The case closed before any answer was filed, any claim construction scheduled, or any Markman hearing set. This timeline is consistent with three scenarios: a licensing or settlement agreement reached privately, a covenant not to sue extended to Stewart Title, or a plaintiff decision to refile in a more favourable venue or against a different defendant. None of these can be confirmed from the public docket.
Pre-answer resolutionFive asserted patents signal a coordinated licensing campaign
Asserting five patents spanning call routing, telephony control, and auction-matching in a single complaint against a title insurer is consistent with PAE (patent assertion entity) portfolio enforcement strategies that target companies relying on third-party communication infrastructure. The breadth of the portfolio asserted suggests Patent Armory may be running parallel actions against other defendants in the financial services and real estate sectors.

Stipulation of dismissal — official text
The court’s order tracks the plaintiff’s own notice of dismissal (Docket Entry No. 12) and carries no substantive finding on infringement, validity, or claim construction. The ‘without prejudice’ designation is legally significant: it preserves Patent Armory’s full right to refile. For Stewart Title Guaranty, the order provides procedural closure but no merits-based shield. Any party assessing risk from these five patents should treat them as fully enforceable and unlitigated.
US9456086B1 and 4 further patents — intelligent call routing and telephony control
The five asserted patents span two core technical domains. The telephony-routing cluster — US9456086B1, US10491748B1, and US10237420B1 — covers systems and methods for intelligently routing inbound communications based on caller attributes, availability data, and routing logic. US7269253B1 addresses telephony control architectures enabling dynamic call handling. The oldest patent, US7023979B1 (application filed 2003), covers a method and system for matching entities in an auction context, suggesting a broader framework applicable to real-time resource allocation beyond pure telephony.
For the financial services and insurance sector, these patents are strategically significant because automated call routing and customer communication management are core infrastructure components. Title insurers, mortgage servicers, and real estate platforms routinely rely on IVR systems, ACD platforms, and cloud-based routing providers — all potential vectors of exposure. The combination of pre-2010 priority dates (US7023979B1, US7269253B1) with more recent continuation-style patents (US10491748B1, US10237420B1) suggests a portfolio deliberately structured to capture both legacy and modern routing implementations.
Should your team run an FTO against these five Patent Armory patents?
Any company operating in financial services, insurance, real estate technology, or customer contact infrastructure that uses intelligent call routing, IVR systems, or automated communication dispatch should assess exposure to this portfolio. The without-prejudice dismissal confirms Patent Armory is actively enforcing these patents. Sector peers of Stewart Title Guaranty — other title insurers, settlement service providers, and mortgage platforms — face structurally similar risk profiles and should not assume they are outside the enforcement perimeter.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map each of the five asserted patents against your product’s communication architecture, identify relevant prior art that may bear on validity, and monitor for new continuation filings from Patent Armory that could extend the portfolio’s reach. Claim monitoring alerts on US9456086B1, US10491748B1, and US10237420B1 in particular are advisable for any company whose customer routing infrastructure may read on the independent claims.

What this case signals for the communication-routing IP landscape
A 75-day dismissal without prejudice from a five-patent assertion is rarely the end of the story — it is often the start of a licensing cycle.
Without-prejudice dismissals from PAEs warrant ongoing monitoring
When a patent assertion entity voluntarily drops a case this quickly, the patents remain live and the enforcement campaign is typically ongoing. Companies in financial services, insurance, and real estate technology that rely on intelligent call routing or IVR infrastructure should treat this dismissal as a signal to review their exposure to these five patents, not as a sign the threat has passed.
Stewart Title has no preclusive protection from this outcome
Unlike a dismissal with prejudice or a summary judgment win, this outcome gives Stewart Title Guaranty zero legal shield against a refiled complaint on the same patents. If no licensing agreement was reached privately, the company remains fully exposed to reassertion. In-house counsel should confirm whether any covenant not to sue was obtained as part of any resolution.
Patent v Stewart — key questions answered
Patent Armory, Inc. filed a patent infringement action against Stewart Title Guaranty Co. on 28 November 2023 in the Southern District of Texas, asserting five patents covering intelligent call routing and telephony systems. The case was dismissed without prejudice on 11 February 2024, after 75 days, following the plaintiff’s own notice of dismissal. No substantive ruling on infringement or validity was issued.
Patent Armory asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These cover intelligent communication routing systems, telephony control with smart call routing, and a method and system for matching entities in an auction context.
A dismissal without prejudice means the court did not rule on the merits of the infringement claims. Patent Armory retains full rights to refile the same claims against Stewart Title Guaranty or other defendants. The patents remain valid and enforceable, and Stewart Title Guaranty received no preclusive finding of non-infringement or invalidity.
The public record does not disclose the reason for dismissal. A 75-day without-prejudice dismissal before any defendant answer was filed is consistent with a private settlement or licensing agreement, a covenant not to sue, or a strategic decision to redirect enforcement. No financial terms or agreements appear on the docket.
The without-prejudice outcome suggests the enforcement campaign may be ongoing. Companies in title insurance, mortgage servicing, and real estate technology that rely on intelligent call routing or IVR infrastructure face a structurally similar risk profile to Stewart Title Guaranty. A freedom-to-operate review against all five asserted patents is advisable for sector peers.
