Case Overview
The Parties
⚖️ Plaintiff
A patent assertion entity (PAE) with no apparent commercial product operations, whose business model centers on licensing and litigating patent portfolios.
🛡️ Defendant
A well-known Brazilian steakhouse restaurant chain operating across the United States, representing a somewhat unconventional target for telephony and auction-technology patent disputes.
Patents at Issue
This case centered on alleged infringement of two patents covering telephony call routing and auction-based entity-matching technology, a pairing that raises immediate questions about licensing strategy and assertion rationale against a restaurant corporation. Both patents are issued U.S. patents registered with the U.S. Patent and Trademark Office (USPTO).
- • US9456086B1 — “Method and system for matching entities in an auction”
- • US7023979B1 — “Telephony control system with intelligent call routing”

The Verdict & Legal Analysis
Outcome
The case was terminated via voluntary dismissal with prejudice pursuant to FRCP 41(a)(1)(A)(i). Critically, the dismissal is with prejudice, meaning Patent Armory cannot re-file the same claims against Texas de Brazil on these patents. Each party agreed to bear its own costs, expenses, and attorneys’ fees — a standard structure in pre-answer resolutions that often accompanies confidential licensing agreements. No damages award, injunctive relief, or judicial ruling on the merits was issued. The specific financial terms, if any, were not disclosed in the public case record.
Key Legal Issues
Because the case resolved before any substantive court ruling, there is no judicial analysis of patent validity, claim construction, or infringement to assess. The legal record is procedurally thin by design. However, several strategic dynamics are worth analyzing:
A dismissal with prejudice protects the defendant from future reassertion on the same patents. This concession by Patent Armory strongly suggests the defendant received something of value in exchange — most plausibly, a covenant not to sue, licensing resolution, or monetary settlement — even though terms were not publicly disclosed. Why no answer was filed before dismissal suggests Texas de Brazil’s defense team moved quickly post-service to negotiate rather than litigate — a cost-effective strategy when facing NPE plaintiffs asserting patents of uncertain commercial relevance to the defendant’s core business.
This case does not establish precedent on patent validity or infringement. However, it reflects a recognizable pattern in NPE litigation: assertion in plaintiff-favorable venues, broad technology claims applied to businesses outside the patent’s apparent target industry, and resolution before substantive judicial engagement. The two patents represent mature technologies where claim scope and invalidity challenges (particularly under 35 U.S.C. § 101 for patent eligibility) could have presented significant obstacles had litigation continued.

Two patents: US9456086B1 (auction-based entity matching) and US7023979B1 (telephony intelligent call routing), both asserted in Case No. 6:24-cv-00123 in the Western District of Texas.
Plaintiff Patent Armory filed a voluntary dismissal under FRCP 41(a)(1)(A)(i) before the defendant answered. The with-prejudice designation bars re-filing of the same claims, typically indicating a negotiated resolution.
It reinforces that pre-answer resolution remains a primary exit path in NPE-driven telephony patent cases, particularly where § 101 eligibility challenges could undermine patent validity at trial.
