Patent Armory v. Grove Collaborative: Call Routing IP Dispute Resolved in 63 Days
Patent Armory, Inc. asserted five patents covering intelligent call routing, telephony control, and auction-matching systems against Grove Collaborative, Inc. in the District of Delaware. The parties stipulated to dismiss all claims with prejudice under Rule 41(a)(1)(A)(ii) — closing the case just 63 days after filing, with each side bearing its own costs.
Five-Patent Call Routing Dispute Ends in Rapid Stipulated Dismissal
Patent Armory, Inc. filed suit against Grove Collaborative, Inc. on January 8, 2025 in the U.S. District Court for the District of Delaware before Judge Maryellen Noreika. The complaint asserted infringement of five U.S. patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity-matching methods. Grove Collaborative, a consumer goods company, was accused of deploying products or systems falling within these patented technologies.
The case closed on March 12, 2025, just 63 days after filing, through a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Under the stipulated terms, all claims asserted by Patent Armory against Grove Collaborative were dismissed with prejudice — permanently barring re-litigation of those specific claims. Grove Collaborative’s counterclaims against Patent Armory were dismissed without prejudice, preserving the defendant’s ability to revive those claims in future proceedings if circumstances warrant.
A resolution within 63 days is notably fast for a five-patent infringement action in Delaware and suggests the parties reached an agreement — possibly including a license or covenant not to sue — before substantive motion practice commenced. The mutual cost-bearing provision and the asymmetric prejudice terms (plaintiff’s claims out with prejudice, defendant’s counterclaims out without prejudice) are consistent with a negotiated settlement rather than a unilateral withdrawal. The specific financial or licensing terms, if any, remain confidential and are not disclosed in the public record.

Rule 41 stipulated dismissal: what the split prejudice terms mean for each party
Rule 41(a)(1)(A)(ii) — dismissal by joint stipulation
Under FRCP 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss an action without a court order once the defendant has served an answer or motion for summary judgment. A with-prejudice dismissal operates as a final adjudication on the merits, foreclosing re-filing of the same claims. This mechanism is the standard vehicle for formalising a negotiated resolution in patent cases.
Stipulated — no court merits rulingPatent Armory’s claims end permanently on the record
Patent Armory’s infringement claims against Grove Collaborative are dismissed with prejudice — it cannot refile the same claims against this defendant on these five patents. This is the standard outcome when a patent holder reaches a resolution (such as a license or covenant not to sue) and needs to provide the defendant with a firm, final bar. The underlying patents remain in force and enforceable against other potential infringers.
Claims barred — patents surviveGrove Collaborative’s counterclaims preserved for future use
Grove Collaborative’s counterclaims were dismissed without prejudice, meaning they were not decided on the merits and could theoretically be re-asserted in a future action. This asymmetric structure — plaintiff out with prejudice, defendant out without — is commercially significant: it suggests Grove retained some optionality, which may reflect negotiating leverage or an agreed risk-sharing arrangement in the underlying resolution.
Counterclaims preservedSwift resolution signals potential licensing activity on call routing IP
A 63-day lifespan with split prejudice terms and own-costs bearing is a profile consistent with an early licensing agreement or structured settlement. For companies operating customer-communication platforms, intelligent routing systems, or auction-based matching services, Patent Armory’s portfolio of five patents remains active enforcement risk. The rapid resolution here may embolden further assertion activity across the sector.

Official order — verbatim text
The stipulation’s asymmetric prejudice structure is analytically significant. Patent Armory’s claims exit with prejudice — a final-merits bar — while Grove Collaborative’s counterclaims exit without prejudice, preserving defendant optionality. The explicit cost-neutrality provision eliminates any fee-shifting inference. Together, these terms are consistent with a confidential licensing resolution: the plaintiff secures a permanent bar on re-litigation while the defendant retains residual procedural leverage, a common commercial trade-off in patent licensing settlements.
US9456086B1 — Intelligent Communication Routing System
US9456086B1 (App. No. 12/719827) is directed to an intelligent communication routing system and method — technology governing how inbound calls or communications are dynamically directed based on rules, attributes, or matching logic. The broader five-patent portfolio spans telephony control systems (US7269253B1, US7023979B1), auction-based entity-matching methods (US10491748B1), and further routing continuations (US10237420B1). These patents reflect technology developed in the mid-2000s through mid-2010s, a period of rapid innovation in cloud communications, contact-centre infrastructure, and programmatic call routing.
The commercial relevance of this portfolio extends well beyond traditional telephony. Companies operating e-commerce customer service platforms, IVR systems, cloud contact centres, or any auction-based lead distribution or routing infrastructure may find their architectures reading on one or more claims in this family. Patent Armory’s willingness to assert all five patents simultaneously in a single action — and to resolve swiftly — is consistent with a licensing programme designed to extract settlements before substantive invalidity or non-infringement defences can be developed.
Should you run an FTO against US9456086B1 and the Patent Armory portfolio?
Any company operating intelligent call routing, telephony control, or auction-based communication matching systems should treat this five-patent portfolio as a priority FTO subject. The patents span application dates from the early 2000s through the mid-2010s, meaning claim scope may be broad relative to modern implementations. E-commerce platforms with customer service routing, cloud contact-centre operators, and lead distribution marketplace operators are all potentially within assertion range — as this case against Grove Collaborative illustrates.

What this case signals for the intelligent call routing IP landscape
A five-patent assertion resolved in under 10 weeks sends a clear signal about enforcement velocity and portfolio leverage in the telephony and routing sector.
Split prejudice dismissals typically indicate a negotiated exit with licence terms
When a plaintiff’s claims are dismissed with prejudice while a defendant’s counterclaims exit without prejudice, it strongly suggests a commercial resolution — often a licence, royalty agreement, or covenant not to sue. Companies in the call routing and customer communication space should treat this pattern as a signal that Patent Armory’s portfolio has demonstrated licensing leverage.
Patent Armory’s five-patent portfolio remains a live enforcement threat post-dismissal
The dismissal with prejudice applies only to Grove Collaborative. US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 remain enforceable. Any company deploying intelligent call routing, telephony control systems, or auction-based communication matching should assess exposure against this portfolio before a demand letter arrives.
Patent v Grove — key questions answered
All infringement claims by Patent Armory against Grove Collaborative were dismissed with prejudice, meaning Patent Armory cannot re-file those specific claims against Grove Collaborative on these five patents. However, the patents themselves remain valid and enforceable against other parties.
The without-prejudice dismissal of Grove’s counterclaims means those claims were not adjudicated on the merits and could theoretically be revived in future proceedings. This asymmetric structure — plaintiff with prejudice, defendant without — is consistent with a negotiated resolution where the defendant retains residual legal optionality as a commercial trade-off.
Patent Armory asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These cover intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity-matching methods — technologies relevant to cloud contact centres and e-commerce customer service platforms.
The case resolved in 63 days from filing to closure — notably fast for a five-patent Delaware infringement action. This timeline, combined with the split-prejudice dismissal and mutual cost-bearing terms, is consistent with an early private settlement or licensing agreement, though specific financial terms are not disclosed in the public record.
No. The with-prejudice dismissal is specific to Grove Collaborative. Patent Armory’s five patents remain enforceable against any other company whose products or systems may infringe. Companies operating intelligent call routing, telephony control, or auction-based communication infrastructure should conduct FTO analysis against this portfolio independently.
