Patent Armory v. ADT: Joint Dismissal With Prejudice After 117 Days
Patent Armory, Inc. filed suit against ADT LLC in the Eastern District of Texas asserting two patents covering auction-based entity matching and intelligent telephony call routing. The parties jointly stipulated to dismissal with prejudice under Rule 41(a)(1)(A)(ii) after just 117 days, with each side bearing its own costs — a resolution pattern consistent with a confidential settlement.
Rapid joint dismissal signals early resolution in E.D. Texas NPE action
Patent Armory, Inc. filed Case No. 2:25-cv-00821 against ADT LLC in the Eastern District of Texas on 20 August 2025, asserting US9456086B1 (method and system for matching entities in an auction) and US7023979B1 (telephony control system with intelligent call routing). The case was assigned to Judge Rodney Gilstrap, one of the most experienced patent trial judges in the country. Patent Armory was represented by DNL Zito and Rabicoff Law LLC; ADT by Cole Schotz PC.
The case closed on 15 December 2025 — just 117 days after filing — via a joint stipulation of dismissal with prejudice filed as Dkt. No. 16 and accepted by the Court. Dismissal with prejudice under Rule 41(a)(1)(A)(ii) means Patent Armory is permanently barred from re-asserting these two patents against ADT on the same claims. The mutual cost-bearing arrangement means neither party extracted a fee-shifting award, which is consistent with a negotiated resolution rather than a contested ruling on the merits.
A 117-day lifespan before any claim construction or substantive motion practice is notably short even for E.D. Texas, which typically sees NPE cases resolved well into the second year. The absence of a publicly disclosed damages figure or licensing term suggests any commercial resolution occurred under a confidential agreement. What drove the early settlement — whether claim scope, ADT’s non-infringement position, or a licensing payment — remains unknown from the public docket.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): what dismissal with prejudice means
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss a case at any time without a court order. When filed with prejudice, the dismissal operates as a final adjudication on the merits — Patent Armory cannot re-file the same infringement claims against ADT on US9456086B1 or US7023979B1. Judge Gilstrap accepted and acknowledged the stipulation, directing the clerk to close the case.
Permanent bar on re-filingPatent Armory’s claims against ADT are permanently resolved
By agreeing to dismissal with prejudice, Patent Armory surrendered any future enforcement rights against ADT on these specific patents for the conduct alleged. The mutual cost-bearing provision means Patent Armory did not secure a fee award. However, the patents themselves remain in force and Patent Armory retains the right to assert them against other defendants — the bar applies only to ADT on these claims.
Patents survive; ADT claim extinguishedADT achieves permanent peace on these two patent claims
ADT secured dismissal with prejudice, meaning it faces no further litigation risk from Patent Armory on US9456086B1 or US7023979B1. The cost-neutral resolution avoided a potentially costly fee motion under 35 U.S.C. § 285 or the Octane Fitness standard. ADT did not obtain a declaratory judgment of invalidity, so the patents remain challengeable by others — but ADT’s exposure is closed.
Litigation risk closed for ADTEarly resolution pattern typical of NPE licensing strategy
The 117-day resolution without public merits ruling is consistent with a licensing payment or covenant not to sue negotiated before substantive motion practice. For competitors operating auction-matching or telephony routing systems, this outcome confirms these patents remain active and enforceable — Patent Armory’s willingness to litigate and resolve quickly suggests an active licensing programme. Companies in adjacent smart-home or call-routing verticals should assess their exposure.

Official order — verbatim text
The joint stipulation recites dismissal ‘with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii)’ — the bilateral mechanism that requires no court order and takes effect upon filing. Judge Gilstrap’s order accepting the stipulation is ministerial rather than a merits ruling; no claim construction, validity finding, or infringement determination was issued. The ‘each party bears its own costs’ clause is a standard mutual release of fee claims and does not indicate relative litigation strength. The practical effect is res judicata as between Patent Armory and ADT on these patents and accused products only.
US9456086B1 & US7023979B1 — Auction Matching and Telephony Call Routing
US9456086B1 (application no. US12/719827) covers a method and system for matching entities in an auction context — technology relevant to real-time bidding, lead-generation marketplaces, and automated pairing platforms. US7023979B1 (application no. US10/385389) covers a telephony control system with intelligent call routing, a foundational claim in IVR, call-centre, and smart-home monitoring communications architectures. Both patents are granted U.S. utility patents asserted at the first-instance level in E.D. Texas.
For the security and smart-home sector, US7023979B1 presents the broader competitive risk: intelligent call routing sits at the operational core of monitored alarm and remote-access systems like those ADT provides. US9456086B1 is more relevant to digital marketplace and lead-routing platforms. Patent Armory’s decision to assert both in a single action against ADT suggests the company believed ADT’s platform touched both functional areas — a claim scope argument that remains untested given the pre-merits dismissal.
Should your product team run an FTO against US9456086B1 and US7023979B1?
Any company operating a telephony-based monitoring service, intelligent call-routing platform, or auction/matching system should assess exposure to these two patents before launching or updating relevant products. The dismissal with prejudice applies only to ADT — both patents remain fully enforceable. Given Patent Armory’s demonstrated willingness to litigate in E.D. Texas, the litigation cost and schedule risk is real. R&D teams integrating call-routing logic or entity-matching auction modules into new product lines are particularly exposed.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US9456086B1 and US7023979B1 against your product architecture, identify prior art that could support an IPR petition, and surface Patent Armory’s full assertion history to assess licensing pattern and settlement range. Running an FTO now — before a demand letter arrives — is significantly cheaper than litigating in Judge Gilstrap’s court on a compressed E.D. Texas schedule.

Cases asserting telephony routing and entity-matching patents before Judge Gilstrap in the Eastern District of Texas follow recognisable NPE enforcement patterns worth benchmarking.
What this case signals for the telephony and smart-home IP landscape
A 117-day NPE action resolved with prejudice in E.D. Texas carries licensing and FTO signals that extend well beyond ADT.
US9456086B1 and US7023979B1 remain enforceable against third parties
Dismissal with prejudice binds only Patent Armory and ADT. Both patents survive intact and Patent Armory retains full enforcement rights against other defendants. Companies offering auction-based matching platforms or intelligent call-routing telephony systems — including smart-home security providers — should treat these patents as active litigation risk.
E.D. Texas / Judge Gilstrap assignment raises early settlement pressure
Cases before Judge Gilstrap in the Eastern District of Texas typically move on a compressed schedule with predictable claim-construction timelines. This creates strong incentive for defendants to resolve early. The 117-day outcome here is consistent with that dynamic — companies served in E.D. Texas should budget for rapid motion practice and consider early licensing analysis.
Patent v ADT — key questions answered
Dismissal with prejudice under Rule 41(a)(1)(A)(ii) permanently bars Patent Armory from re-asserting US9456086B1 and US7023979B1 against ADT on the same claims. ADT is released from litigation risk on these patents. However, both patents remain enforceable against all other defendants — the bar is bilateral only between these two parties.
Patent Armory asserted two patents: US9456086B1, covering a method and system for matching entities in an auction, and US7023979B1, covering a telephony control system with intelligent call routing. Both remain active U.S. utility patents following the dismissal.
The 117-day resolution is faster than the typical E.D. Texas patent litigation timeline and suggests the parties reached a commercial agreement before any substantive motion practice or claim construction. The mutual cost-bearing provision and absence of a public damages figure are consistent with a confidential licensing arrangement, though the public record does not confirm this.
No. The dismissal with prejudice binds only Patent Armory and ADT. US9456086B1 and US7023979B1 remain fully enforceable against third parties. Companies offering telephony call-routing, smart-home monitoring, or auction-matching platforms should independently assess their freedom to operate against these patents.
