Patent Armory v. Infosys: Intelligent Routing Patents Dismissed in 56 Days
Patent Armory, Inc. sued Infosys over five patents spanning intelligent call routing, telephony control, and entity-matching auction systems in the Eastern District of Texas. The case was voluntarily dismissed without prejudice just 56 days after filing, before Infosys filed any answer or dispositive motion.
A swift voluntary exit: five patents, 56 days, and an open door to refile
On April 2, 2025, Patent Armory, Inc. filed suit against Infosys, Inc. in the U.S. District Court for the Eastern District of Texas before Judge Rodney Gilstrap, asserting infringement of five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The asserted patents collectively cover intelligent communication routing systems, telephony control with intelligent call routing, and methods for matching entities in an auction context — technologies directly relevant to enterprise software and communications platforms.
Before Infosys filed an answer or moved for summary judgment, Patent Armory filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). On May 27, 2025, Judge Gilstrap accepted and acknowledged the dismissal, formally closing the case. Each party was ordered to bear its own costs, expenses, and attorneys’ fees, meaning no financial judgment was entered against either side. The without-prejudice designation is legally significant: Patent Armory retains the ability to reassert the same five patents against Infosys in a future action.
A 56-day lifecycle is notably short even by EDTX standards, and the pre-answer timing of the dismissal is consistent with either an early-stage settlement, a licensing conversation that resolved the dispute, or a strategic reassessment of claim scope before Infosys mounted a formal defense. The public record does not disclose whether any consideration changed hands. The absence of a defendant law firm on record and the lack of any Infosys response filings suggests the case ended before adversarial proceedings meaningfully commenced.
Filing to Voluntary dismissal in 56 days
56 days — well below the median EDTX patent case lifespan, suggesting early resolution before substantive litigation
Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(i) allows dismissal as of right before answer
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because Infosys had not yet responded, Patent Armory exercised this right unilaterally. The court’s role was limited to accepting and acknowledging the dismissal — no merits ruling was made on any of the five asserted patents.
No merits adjudicationWithout prejudice preserves Patent Armory’s right to refile
A dismissal without prejudice means the plaintiff is not barred from reasserting the same claims in a future lawsuit. Patent Armory retains the ability to bring a new action against Infosys on any or all of the five patents. By contrast, a dismissal with prejudice would operate as a final judgment on the merits, permanently extinguishing those claims. The public record is silent on whether any agreement between the parties influenced the choice of without-prejudice designation.
Claims remain viableInfosys exits with no judgment but faces potential re-litigation
Infosys secured a clean exit — no infringement finding, no damages, no injunction, and no attorneys’ fee award was entered against either party. However, the without-prejudice dismissal means Infosys has not obtained a legal determination that it does not infringe or that the patents are invalid. The threat of re-filing on the same five intelligent routing patents remains live. Infosys may wish to evaluate its FTO position across the asserted portfolio as a precautionary measure.
No liability — refile risk remainsPre-answer exits in EDTX often signal licensing activity or strategic repositioning
When a patent assertion entity files in EDTX and dismisses voluntarily before the defendant answers, it is consistent with a licensing negotiation reaching resolution, a demand letter strategy, or a reassessment of litigation economics. Enterprise IT vendors operating in intelligent routing, telephony control, or auction-matching technology should note that the five asserted patents remain in force. Similar companies to Infosys may be targets for assertion from the same portfolio.

Official order — verbatim text
The court’s order accepts Patent Armory’s Rule 41(a)(1)(A)(i) notice, making clear that dismissal was effective as a matter of right — no judicial discretion was exercised on the merits. The phrase ‘dismissed without prejudice’ is the operative legal term: no finding of infringement, validity, or enforceability was made on any of the five asserted patents. The fee-bearing clause — ‘each party to bear its own costs’ — is standard for Rule 41 pre-answer dismissals and does not imply any settlement payment was made.
US9456086B1 and four further patents — intelligent communication routing and telephony control
The five asserted patents cover a range of intelligent communication and routing technologies. US9456086B1 and US10491748B1 relate to intelligent communication routing systems, with application dates in 2010 and 2017 respectively, suggesting coverage of both earlier-generation and more modern routing architectures. US7269253B1 and US7023979B1 address telephony control systems with intelligent call routing, filed in the mid-2000s and representative of foundational IP in enterprise call handling. US10237420B1 covers methods and systems for matching entities in an auction context, extending the portfolio into dynamic allocation and matching logic.
This portfolio is strategically positioned to assert against enterprise software vendors offering cloud-based or on-premise communications platforms, contact center solutions, and AI-driven routing engines. The age spread — from early 2000s to late 2010s — means earlier patents may be approaching expiry while later-filed patents carry longer exclusivity horizons. For competitors and technology vendors adjacent to Infosys’s enterprise services business, the portfolio represents a credible assertion risk, particularly given Patent Armory’s demonstrated willingness to file in the EDTX before Judge Gilstrap.
Should you run an FTO against US9456086B1 and the Patent Armory routing portfolio?
Any enterprise software vendor, contact center platform provider, or cloud communications company whose products include intelligent call routing, telephony control, or dynamic entity-matching functionality should treat this portfolio as a priority FTO target. Patent Armory’s dismissal without prejudice leaves all five patents enforceable and re-assertable. If your product stack intersects with IVR systems, ACD routing logic, or auction-based resource allocation, an FTO analysis against these patents — particularly the 2017–2018 application date patents — is a commercially prudent step.
PatSnap Eureka’s FTO Search Agent can map each of the five asserted patents against your product’s technical features, identify independent claims with the broadest scope, surface prior art that may narrow enforceability, and flag any continuation or family member patents that could extend the portfolio’s reach. Running a structured FTO now — before any demand letter arrives — is significantly less costly than responding to an EDTX filing. Eureka’s patent family analysis will also reveal whether Patent Armory holds continuation applications that have not yet been asserted.

What this case signals for the enterprise communications IP landscape
Five asserted patents, no merits ruling, and a live portfolio — the strategic picture extends well beyond this single docket.
Pre-answer EDTX dismissals rarely mean the dispute is truly over
Voluntary dismissals without prejudice before an answer — particularly by patent assertion entities in the Eastern District of Texas — frequently suggest a licensing resolution or a pivot to a parallel demand strategy. The five patents remain enforceable and can be re-asserted. Enterprise software companies operating in intelligent routing and telephony should treat this outcome as a signal to audit exposure, not a clearance.
Judge Gilstrap’s court is a high-velocity patent venue — early preparation matters
Judge Rodney Gilstrap in the EDTX is among the most experienced patent trial judges in the U.S. by case volume. Being served in his court — even in a case that resolves quickly — signals that plaintiff’s counsel selected the venue deliberately. Companies in enterprise communications, routing, or auction-matching systems should have pre-litigation IP risk assessments in place before any complaint is served.
Patent v Infosys — key questions answered
A dismissal without prejudice means Patent Armory is not barred from refiling the same claims against Infosys. The five asserted patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — remain in force and can be reasserted in a new action. No merits ruling on infringement, validity, or enforceability was made in Case No. 2:25-cv-00328.
The case was dismissed 56 days after filing, before Infosys filed an answer or any dispositive motion. This pre-answer timing enabled Patent Armory to exercise its Rule 41(a)(1)(A)(i) right of voluntary dismissal without court approval. The public record does not disclose the reason, but this pattern is consistent with early licensing discussions, settlement, or a strategic reassessment of litigation posture.
Patent Armory asserted five patents: US9456086B1 (intelligent communication routing system), US10491748B1 (intelligent communication routing), US7269253B1 (telephony control with intelligent call routing), US7023979B1 (telephony control system), and US10237420B1 (method and system for matching entities in an auction). Together they cover enterprise communication routing and dynamic matching technologies.
Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure allows a plaintiff to voluntarily dismiss a case without a court order if the defendant has not yet served an answer or a motion for summary judgment. Because Infosys had not filed either, Patent Armory could file a Notice of Voluntary Dismissal as of right. Judge Gilstrap accepted and acknowledged the notice on May 27, 2025, closing the case with no merits adjudication.
Not necessarily. The order that each party bear its own costs, expenses, and attorneys’ fees is the default rule under Rule 41(a)(1)(A)(i) voluntary dismissals and does not imply a settlement payment was made. The public docket contains no settlement agreement or licensing terms. Whether any consideration changed hands privately between the parties is not disclosed in the court record.
