Patent Armory, Inc. v. Gusto, Inc.: Dismissal in Call Routing Patent Dispute

Introduction

A patent infringement action filed in the Delaware District Court between Patent Armory, Inc. and payroll technology company Gusto, Inc. concluded with a stipulated dismissal just 47 days after filing. Case No. 1:25-cv-00467, centered on five patents covering intelligent call routing and telephony control systems, ended when both parties agreed to dismiss all claims under Federal Rule of Civil Procedure 41(a)(1)(A)(ii) — with claims against Gusto dismissed with prejudice and counterclaims against Patent Armory dismissed without prejudice.

For patent attorneys tracking non-practicing entity (NPE) assertion patterns, IP professionals managing telephony-adjacent patent risk, and R&D teams building communication infrastructure, this case offers a compact but instructive window into how modern patent infringement disputes in the communications technology space resolve — often quickly, quietly, and strategically.

Case Overview

The Parties

Patents at Issue

Five U.S. patents were asserted, spanning telephony and intelligent routing technologies. These patents collectively cover: intelligent communication routing systems and methods, telephony control systems with intelligent call routing, and methods and systems for matching entities in an auction.

• • US7,023,979 B1 — Intelligent communication routing systems and methods
• • US7,269,253 B1 — Telephony control systems with intelligent call routing
• • US9,456,086 B1 — Intelligent communication routing methods
• • US10,237,420 B1 — Methods and systems for matching entities in an auction
• • US10,491,748 B1 — Telephony systems with distributed control

The Accused Products

Patent Armory alleged that Gusto’s systems — specifically capabilities tied to communication routing and entity-matching workflows within its HR, payroll, and benefits platform — infringed these telephony patents. The commercial significance lies in how modern HR platforms increasingly embed voice, messaging, and workflow routing features that overlap with legacy telecommunications patent portfolios.

Legal Representation

Plaintiff Patent Armory, Inc. was represented by Antranig N. Garibian of Garibian Law Offices, PC. Defendant Gusto, Inc. was represented by Grayson P. Sundermeir of Fish & Richardson PC, a leading IP litigation firm.

Litigation Timeline & Procedural History

The 47-day resolution is notably swift, indicating the parties reached a resolution before substantive motions were decided. No record of claim construction proceedings, summary judgment motions, or Markman hearings appears in the available case data.

The Verdict & Legal Analysis

Outcome

The case terminated via stipulated dismissal under FRCP 41(a)(1)(A)(ii). Key terms:

• • Claims against Gusto: Dismissed WITH PREJUDICE — Patent Armory cannot refile these same infringement claims against Gusto on these patents.
• • Counterclaims against Patent Armory: Dismissed WITHOUT PREJUDICE — Gusto preserves its right to pursue declaratory judgment or invalidity claims in future proceedings.
• • Fee allocation: Each party bears its own costs, expenses, and attorneys’ fees — no fee-shifting.

No damages were awarded, and no injunctive relief was entered. The infringement action resolved without any court ruling on the merits of validity or infringement.

Verdict Cause Analysis

The operative legal outcome is the with-prejudice dismissal: Patent Armory has permanently forfeited its right to assert these five patents against Gusto based on the accused products. This outcome was likely driven by:

• Early Defense Pressure: Fish & Richardson’s engagement as defense counsel likely signaled aggressive early motion practice, leading Patent Armory to reassess litigation economics.
• Patent Eligibility Risk (§ 101): Patents covering communication routing and entity-matching methodologies often face 35 U.S.C. § 101 (Alice/Mayo) eligibility challenges. Strong § 101 arguments may have prompted Patent Armory’s withdrawal.
• Commercial Calculus: Gusto’s robust defense altered Patent Armory’s expected value calculation, making an early dismissal more favorable than protracted, costly litigation.

Legal Significance

The without-prejudice preservation of Gusto’s counterclaims is a meaningful strategic reserve. This outcome reflects sophisticated defense negotiation, illustrating the **FRCP 41(a)(1)(A)(ii) mechanism** as a common litigation exit ramp for NPE plaintiffs when early defense posture renders continued assertion economically unviable.

Industry & Competitive Implications

This case reflects a broader pattern of legacy telephony patent assertion against modern SaaS platforms — a trend accelerating as communication features become embedded in HR, CRM, and workflow tools. Companies like Gusto, whose core product is payroll and workforce management, increasingly find themselves defending patents originally drafted for traditional telecommunications environments.

The five-patent portfolio asserted here — spanning nearly two decades of telephony innovation from early 2000s filing dates through mid-2010s continuation practice — exemplifies how NPEs construct assertion portfolios from aging but broad communications technology claims.

For the HR tech and SaaS sectors broadly, this case signals continued NPE attention to platforms incorporating routing, matching, and communication functionalities. Companies building integrated communication layers into enterprise software should prioritize proactive patent clearance and consider defensive publication strategies.
