Patent Armory v. MassMutual: Five Call Routing Patents, Dismissed in 26 Days
Patent Armory, Inc. sued Massachusetts Mutual Life Insurance Company in the District of Massachusetts, asserting five patents covering intelligent call routing, auction-based entity matching, and telephony control systems. The parties filed a stipulated dismissal just 26 days after filing — with claims against MassMutual dismissed with prejudice and counterclaims against Patent Armory dismissed without prejudice.
A 26-Day Patent Assertion Against MassMutual Ends in Split Dismissal
On 4 December 2024, Patent Armory, Inc. filed suit against Massachusetts Mutual Life Insurance Company (MassMutual) in the District of Massachusetts, asserting five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The asserted patents cover intelligent communication routing systems, auction-based entity matching methods, and telephony control architectures — technology relevant to enterprise call-centre and customer-service routing infrastructure.
The case closed on 30 December 2024 via a Rule 41(a)(1)(A)(ii) stipulated dismissal. Critically, the dismissal was asymmetric: all of Patent Armory’s claims against MassMutual were dismissed with prejudice, permanently barring re-assertion of the same claims against MassMutual on those patents, while MassMutual’s counterclaims were dismissed without prejudice, preserving MassMutual’s right to revive those claims in future proceedings.
The 26-day resolution is unusually swift and suggests the parties reached an accommodation — or that Patent Armory reconsidered its position — before any substantive litigation steps occurred. The public record does not disclose whether any consideration changed hands. The without-prejudice carve-out for counterclaims is commercially significant: it suggests MassMutual retained optionality, possibly including a declaratory judgment posture, should Patent Armory assert related patents in future.

Asymmetric Rule 41 dismissal: what the split terms mean for each party
Rule 41(a)(1)(A)(ii) stipulated dismissal — what it means
A Rule 41(a)(1)(A)(ii) dismissal is a voluntary, court-approved stipulation signed by all parties. No judicial ruling on the merits occurred. The with-prejudice designation on Patent Armory’s claims is the operative constraint: it carries res judicata effect, meaning Patent Armory cannot refile the same claims against MassMutual on these five patents.
No merits rulingClaims vs. counterclaims: why the split designation matters
The stipulation creates a deliberate asymmetry. Patent Armory’s infringement claims are extinguished with prejudice — a hard stop. MassMutual’s counterclaims, dismissed without prejudice, remain live in theory. This structure is consistent with MassMutual negotiating to preserve its declaratory judgment or invalidity options should Patent Armory assert these patents elsewhere or related patents against MassMutual in future.
Counterclaims preservedPatent Armory loses its right to pursue MassMutual on these five patents
The with-prejudice dismissal of Patent Armory’s claims forecloses any future infringement action against MassMutual based on the five asserted patents. Whether this reflects a licensing agreement, a weakness identified in early case analysis, or a strategic retreat is not disclosed in the public record. Patent Armory’s enforcement options against other defendants on these patents remain unaffected.
Enforcement barred vs. MassMutualMassMutual retains flexibility; other defendants should monitor Patent Armory’s portfolio
For MassMutual, the without-prejudice counterclaims provide a residual defensive tool. For other enterprises deploying intelligent call routing or telephony control infrastructure, Patent Armory’s five-patent portfolio remains active and enforceable. The rapid resolution may signal either licensing activity or prior art concerns — either way, freedom-to-operate analysis against these patents is advisable for potential defendants.

Official order — verbatim text
The stipulation’s language is precise and consequential: ‘all claims against Defendant WITH PREJUDICE and all counterclaims against Plaintiff WITHOUT PREJUDICE’ creates two legally distinct outcomes within a single filing. The with-prejudice element operates as a final adjudication for res judicata purposes on the asserted patents against MassMutual, while the without-prejudice element on counterclaims explicitly preserves MassMutual’s future litigation options. No court found infringement or invalidity — this is a procedural endpoint, not a substantive one.
US9456086B1 — Intelligent Communication Routing Systems and Methods
The five asserted patents span two core technology areas: intelligent communication routing (US9456086B1, US10491748B1, US10237420B1) and telephony control with auction-based entity matching (US7269253B1, US7023979B1). The application dates range from early-2000s filings (US10/385389, US11/387305) through to mid-2010s continuations, suggesting a well-maintained family built around foundational call-routing and skills-based routing innovations. The ‘086 and ‘748 patents are the most recent grants and likely reflect the broadest claims in the portfolio.
Intelligent call routing and auction-based matching technologies are embedded in enterprise contact-centre platforms, insurance customer service operations, and financial services IVR infrastructure. A patent assertion entity holding this portfolio can plausibly target a wide range of financial services and insurance companies whose customer service operations route inbound calls using algorithmic or skills-based systems. The portfolio’s age and family structure suggest prior art searches will be productive, but the multi-continuation strategy indicates the patentee has actively maintained claim scope.
Should your team run an FTO against US9456086B1 and the Patent Armory call routing portfolio?
If your organisation operates intelligent call routing, skills-based routing, ACD systems, or auction-style queue management for customer service — particularly in financial services or insurance — the Patent Armory portfolio presents a non-trivial FTO concern. The five-patent family covers multiple implementation angles, and the with-prejudice dismissal against MassMutual confirms Patent Armory is actively asserting these patents. Other insurers and financial institutions deploying similar routing infrastructure should not assume they are out of scope.
PatSnap Eureka’s FTO Search Agent can map your contact-centre routing implementation against the claim scope of US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1, surface invalidating prior art across the full continuation family, and identify design-around options. Given the PAE enforcement pattern suggested by this case, early FTO analysis is materially cheaper than reactive litigation defence.

What this case signals for the call routing and telephony IP landscape
A 26-day lifecycle and asymmetric dismissal terms reveal strategic positioning on both sides of this patent assertion.
With-prejudice dismissal permanently closes the MassMutual enforcement channel
Patent Armory cannot refile these five infringement claims against MassMutual. For MassMutual’s IP team, the case is effectively resolved — but the without-prejudice counterclaims mean formal closure is conditional on Patent Armory’s future conduct with related patents.
Speed of resolution suggests pre-litigation leverage, not litigation strength
Cases resolved in under 30 days typically settle before any discovery or claim construction occurs. This pattern is consistent with a demand-letter-to-licence cycle rather than a merits-driven resolution, though no licence or payment is confirmed in the public record.
Patent v Massachusetts — key questions answered
Patent Armory filed a patent infringement suit against MassMutual on 4 December 2024 in the District of Massachusetts, asserting five call routing and telephony patents. The case was stipulated to dismiss on 30 December 2024 — 26 days later — with Patent Armory’s claims dismissed with prejudice and MassMutual’s counterclaims dismissed without prejudice under Rule 41(a)(1)(A)(ii).
Patent Armory asserted five patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These patents cover intelligent communication routing systems, auction-based entity matching methods, and telephony control systems — technologies relevant to enterprise call-centre and customer service routing infrastructure.
A dismissal with prejudice carries res judicata effect: Patent Armory is permanently barred from refiling the same infringement claims against MassMutual on these five patents. The dismissal does not affect Patent Armory’s ability to assert the same patents against other defendants.
A without-prejudice dismissal preserves the right to refile. MassMutual’s counterclaims — likely covering invalidity or declaratory judgment — were not extinguished and could be revived in future proceedings. This asymmetric structure is consistent with MassMutual negotiating to retain a defensive option should Patent Armory assert related patents against it in future.
The with-prejudice dismissal in this case confirms Patent Armory is actively enforcing its portfolio. Enterprises — particularly insurers and financial services firms — that deploy intelligent call routing, skills-based ACD, or auction-based queue management should assess FTO exposure against US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The portfolio’s multi-continuation structure suggests broad claim coverage across implementation variants.
