ReadyComm LLC vs. Avaya LLC: Voluntary Dismissal in Telephone Communication Patent Case

In one of 2025’s fastest-resolved patent infringement actions, ReadyComm LLC voluntarily dismissed its lawsuit against Avaya LLC just 18 days after filing — before Avaya had filed any responsive pleading. The case, docketed as 3:25-cv-00640 in the Texas Northern District Court, centered on U.S. Patent No. 9,179,011 B1, covering a Telephone Communication System and Method of Using. Filed on March 17, 2025, and closed on April 4, 2025, the dismissal was entered without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i).

For patent attorneys, IP professionals, and R&D teams operating in the communications technology sector, this case — though brief — offers meaningful signals about litigation strategy, plaintiff behavior in the patent assertion ecosystem, and the procedural leverage built into early-stage dismissal rights. The telephone communication patent infringement landscape remains active, and this filing-and-withdrawal pattern warrants careful analysis.

Case Overview

The Parties

The Patent at Issue

This case involved U.S. Patent No. 9,179,011 B1, covering a *Telephone Communication System and Method of Using*, addressing how telephone-based communication systems are structured and operationalized — a broad area with direct relevance to enterprise telephony platforms like those offered by Avaya.

• • US9,179,011 B1 — Telephone Communication System and Method of Using
• • Application Number: US14/727,176
• • Technology Area: Telephone Communication Systems

The Accused Product(s)

The complaint alleged infringement related to Avaya’s telephone communication system products and services. Given Avaya’s extensive product suite — spanning cloud contact centers, PBX systems, and unified communications platforms — the scope of potential accused products was commercially significant, though specific accused product lines were not detailed in the publicly available filing data.

Legal Representation

Plaintiff’s Counsel: Benjamin C. Deming and Isaac Philip Rabicoff from Law Firms: DNL Zito and Rabicoff Law LLC.

Both firms have documented experience in patent assertion and licensing matters. Notably, no defendant counsel was recorded, consistent with the case closing before Avaya engaged in formal defense proceedings.

Litigation Timeline & Procedural History

The case was filed in the Texas Northern District Court, a venue with a well-established docket for patent infringement actions and home to Chief Judge Ed Kinkeade. Texas Northern has historically attracted patent plaintiffs due to its familiarity with complex IP litigation and predictable procedural timelines.

The 18-day duration is exceptionally brief by any litigation standard. The dismissal was filed pursuant to FRCP 41(a)(1)(A)(i), which permits a plaintiff to dismiss an action without a court order — and without prejudice — before the defendant has served an answer or a motion for summary judgment. The case record confirms Avaya had not yet answered the complaint at the time of dismissal, making the voluntary withdrawal procedurally straightforward.

No claim construction proceedings, discovery disputes, summary judgment motions, or trial activity occurred during this window.

The Verdict & Legal Analysis

Outcome

The case was voluntarily dismissed without prejudice by ReadyComm LLC on April 4, 2025. No damages were awarded. No injunctive relief was granted. No consent judgment or settlement terms were publicly disclosed.

A dismissal “without prejudice” is legally significant: it preserves ReadyComm’s right to re-file the same infringement claims against Avaya in the future, subject to applicable statutes of limitations and any other procedural constraints.

Verdict Cause Analysis

The stated verdict cause is an Infringement Action, but the case concluded without any judicial determination on the merits. No findings regarding patent validity, claim construction, or actual infringement were made by the court. The rapid closure reflects a purely plaintiff-driven procedural decision.

The absence of any defendant filing — no answer, no Rule 12(b)(6) motion to dismiss, and no motion for summary judgment — confirms the case ended entirely on ReadyComm’s initiative. This is consistent with several strategic scenarios:

• • Pre-litigation licensing resolution: Parties may have reached a private licensing agreement or settlement not disclosed in the public record.
• • Strategic withdrawal: ReadyComm may have reassessed litigation risk, claim strength, or resource allocation following the filing.
• • Forum or timing recalibration: Plaintiff counsel may have identified procedural or strategic reasons to refile in a different venue or at a different time.

Without court-disclosed settlement terms or party statements, the precise motivation for dismissal remains undisclosed.

Legal Significance

This case carries limited direct precedential value given its pre-answer dismissal — no claim construction order, no validity ruling, and no infringement analysis were produced. However, it contributes to a broader observable pattern in patent assertion activity: use of FRCP 41(a)(1)(A)(i) as a low-cost exit mechanism when early-stage reassessment favors withdrawal.

From a patent validity and claim construction standpoint, US9,179,011 B1 remains untested in this litigation. Patent attorneys tracking telephone communication system patent litigation should note that the patent’s claims have not been adjudicated in this proceeding.

Strategic Takeaways

For Patent Holders and Licensors:

• • Voluntary dismissal without prejudice under FRCP 41(a)(1)(A)(i) remains a powerful early-exit tool, preserving future assertion rights while avoiding adverse rulings.
• • Filing in plaintiff-friendly venues like Texas Northern can create early settlement pressure even without full litigation commitment.
• • Rapid dismissal patterns may indicate parallel licensing discussions occurring outside the court record.

For Accused Infringers:

• • Early engagement with plaintiff counsel — even before formal answer deadlines — can facilitate pre-answer resolution and reduce litigation costs significantly.
• • Monitor re-filing risk: a without-prejudice dismissal means the threat is not permanently extinguished.
• • Conduct proactive freedom-to-operate (FTO) analysis on US9,179,011 B1 if your products involve telephone communication system architectures.

For R&D Teams:

• • Avaya-adjacent technology developers should review claim scope of US9,179,011 B1 via the USPTO Patent Full-Text Database to assess design-around opportunities.
• • The filing signal alone — regardless of dismissal — indicates ReadyComm views this patent as commercially assertable against enterprise telephony platforms.

Industry & Competitive Implications

The ReadyComm v. Avaya filing reflects ongoing assertive activity in the enterprise communications and telephony patent space. Avaya, having navigated significant corporate restructuring in recent years, remains a high-profile target in patent assertion campaigns given its market visibility in contact center and unified communications markets.

For companies developing or deploying telephone communication systems — including cloud PBX, VoIP platforms, contact center infrastructure, and unified communications solutions — this case underscores several strategic realities:

• • PAE activity in communications technology remains elevated. Patent assertion entities continue to target established enterprise technology vendors with broad telecommunications patents.
• • Without-prejudice dismissals preserve future risk. Technology vendors receiving pre-answer dismissals should treat them as deferred, not resolved, threats.
• • Licensing exposure exists across the supply chain. Both platform developers and enterprise deployers of telephone communication systems may face assertion risk from patents like US9,179,011 B1.

Companies in this space should consider proactive patent landscape mapping of issued patents in the telephone communication system category, particularly those held by assertion-focused entities.
