Patent Armory Inc. v. Canon, Inc. — Voluntarily Dismissed After 4 Days
Patent Armory Inc. filed a five-patent infringement action against Canon, Inc. in the New Jersey District Court targeting intelligent call routing, telephony control, and auction-based communication matching technologies. The case was dismissed voluntarily without prejudice just four days after filing, before Canon filed any response.
Five-patent call routing suit against Canon collapses in four days
On 13 October 2024, Patent Armory Inc. filed a patent infringement action in the United States District Court for the District of New Jersey against Canon, Inc. The complaint asserted five patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing systems, telephony control with intelligent call routing, and methods for matching entities in an auction context. The accused products and methods relate to Canon’s communication and routing infrastructure.
Just four days after filing, on 17 October 2024, plaintiff Patent Armory Inc. filed a voluntary notice of dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Canon had not yet answered the complaint or moved for summary judgment, Patent Armory was entitled to dismiss as of right without a court order. The public record does not specify whether the dismissal was intended to be with or without prejudice; the FRCP default for a first voluntary dismissal under 41(a)(1)(A)(i) is without prejudice unless otherwise stated.
A four-day lifespan is exceptionally short even among NPE filings, suggesting that the dismissal may have followed a prompt pre-litigation communication from Canon, an internal reassessment of claim scope or venue, or a preliminary agreement between the parties — none of which is confirmed by the public record. The five asserted patents remain in force unless subsequently challenged or expired, and the without-prejudice posture means Patent Armory retains the option to refile the claims subject to applicable limitations and estoppel rules.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a unilateral right to exit before answer
FRCP 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because Canon had not yet responded, Patent Armory could — and did — file a notice of dismissal as of right. No judicial approval was required, and no merits ruling was issued. The dismissal takes effect upon filing of the notice.
No merits decidedThe public record is silent on prejudice designation
Under FRCP 41(a)(1)(B), a first voluntary dismissal is without prejudice unless the notice states otherwise. The verbatim verdict text on record does not explicitly designate with or without prejudice. Practitioners should note the distinction is material: without prejudice preserves the right to refile; with prejudice operates as a final adjudication on the merits. Based on the rule’s default and the language of the notice, this dismissal is most likely without prejudice — but the public record does not confirm this definitively.
Likely without prejudice — not confirmedPatent Armory retains its patents and likely its right to refile
Provided this is Patent Armory’s first voluntary dismissal of these claims against Canon — consistent with the FRCP 41(a)(1)(B) default — Patent Armory retains its asserted patents and the option to bring a renewed action. A second voluntary dismissal of the same claims against the same defendant would operate as an adjudication on the merits. The four-day timeline suggests no licence, settlement, or covenants not to sue were publicly recorded.
Right to refile likely preservedCanon exits without a merits ruling — but cloud remains
Canon faced no adjudication on infringement or validity and bears no court-ordered liability. However, the dismissal without prejudice means the five asserted patents — covering intelligent communication routing and telephony control — continue to present a potential enforcement risk. Canon and similarly situated communication technology companies should monitor Patent Armory’s assertion activity and consider the FTO status of these patents in product planning.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) explicitly and confirms Canon had neither answered nor moved for summary judgment. This procedural posture is significant: it means the dismissal was a unilateral plaintiff right requiring no court action and producing no merits ruling on infringement or validity. The absence of any prejudice designation in the quoted text means the FRCP 41(a)(1)(B) default — without prejudice — most likely governs, preserving Patent Armory’s right to refile these claims subject to the two-dismissal rule and applicable statutes of limitations.
US9456086B1 and four further patents — intelligent call routing and telephony control
The five asserted patents cover a cluster of innovations in intelligent communication routing and telephony management. US9456086B1 and US10491748B1 target routing logic for communication systems, while US7269253B1 and US7023979B1 — with application dates in the mid-2000s — address foundational telephony control architectures. US10237420B1 covers auction-based entity matching, suggesting a secondary monetisation pathway in dynamic communication resource allocation. Together the portfolio spans nearly 15 years of application activity, from early VoIP infrastructure to modern routing intelligence.
For any company operating in unified communications, contact centre platforms, VoIP, or cloud telephony, this patent cluster represents a meaningful risk surface. The combination of older foundational patents with more recent continuation-style filings is a classic NPE portfolio construction strategy designed to capture both legacy infrastructure and modern implementations. Canon’s communication product lines — including its document management and enterprise communication systems — were the named target, but the claims as drafted could reach a broader set of defendants in the UCaaS and contact centre software markets.
Should you run an FTO against US9456086B1 and the Patent Armory call routing portfolio?
Any product team developing or deploying intelligent call routing, telephony control systems, VoIP infrastructure, or auction-based communication matching should assess exposure against this five-patent portfolio. The without-prejudice dismissal means Patent Armory retains full enforcement rights. Companies in UCaaS, cloud contact centres, or enterprise communication platforms are the most likely next targets given the claim scope.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the independent claims of each asserted patent, flag claim elements most likely to read on modern routing and telephony architectures, and surface prior art that could support a pre-emptive IPR or § 101 challenge. Given the portfolio’s age spread, an automated claim chart across all five patents provides the fastest path to a defensible risk assessment.

What this case signals for the communication routing IP landscape
A four-day patent suit lifecycle and five asserted communication routing patents point to patterns worth tracking for any company in the telephony or UC space.
Ultra-short NPE filings often signal pre-suit leverage tactics
When a patent assertion entity files and voluntarily dismisses within days — before the defendant even answers — it typically suggests the filing itself was a negotiating lever. Whether Canon responded with a cease-and-desist, a licensing counter, or a validity challenge is unknown, but practitioners should treat rapid dismissals as potential indicators of parallel licensing discussions rather than genuine withdrawal.
Five patents across call routing and telephony expand the enforcement surface
Patent Armory asserted patents spanning intelligent call routing, auction-based entity matching, and telephony control systems. This multi-patent stack suggests a portfolio licensing posture. Companies offering UCaaS, contact centre software, or VoIP infrastructure should assess whether their products map to any of the five asserted patent claims, as a refiling remains legally available.
PATENT v Canon — key questions answered
Patent Armory Inc. filed a five-patent infringement action against Canon, Inc. in the District of New Jersey on 13 October 2024, asserting patents covering intelligent call routing, telephony control, and auction-based entity matching. The case was voluntarily dismissed four days later on 17 October 2024 under FRCP 41(a)(1)(A)(i), before Canon answered the complaint. No merits ruling was issued.
Patent Armory asserted five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These cover intelligent communication routing systems, telephony control with intelligent call routing, and a method and system for matching entities in an auction. The portfolio spans application dates from the early 2000s through 2017.
The public record does not explicitly state with or without prejudice. Under FRCP 41(a)(1)(B), a first voluntary dismissal is without prejudice by default unless the notice specifies otherwise. The notice of dismissal filed by Patent Armory invokes Rule 41(a)(1)(A)(i) and does not include a prejudice designation, making the without-prejudice default most likely applicable — but this is not confirmed on the face of the record.
Likely yes, provided this was Patent Armory’s first voluntary dismissal of these claims against Canon. Under FRCP 41(a)(1)(B), the ‘two dismissal rule’ provides that a second voluntary dismissal of the same claims against the same defendant operates as an adjudication on the merits — effectively a permanent bar. A single prior dismissal without prejudice preserves the right to refile, subject to applicable statutes of limitations.
A four-day filing-to-dismissal window — before the defendant even answers — is consistent with a pre-suit licensing or settlement demand strategy where the complaint itself is the leverage mechanism. It may also reflect an internal reassessment of claim scope, venue, or defendant identity. The public record does not confirm any agreement between the parties, and no financial terms are disclosed. Practitioners typically treat such rapid dismissals as indicators of parallel licensing negotiations rather than a concession on the merits.
