xMatrix LLC vs. Vivion, Inc.: Voluntary Dismissal in Multi-Services Gateway Patent Case

Case Overview

The Parties

The Patent at Issue

This case centered on **U.S. Patent No. US12300366B2** (Application No. US18/453927), covering a “multi-services application gateway and system employing the same” — a technology with significant relevance to modern enterprise networking and cloud service delivery.

• • US12300366B2 — Multi-services application gateway and system employing the same

The Accused Product

The accused product category is identified as a **”Multi-services application gateway and system employing the same”** — technologies increasingly central to SaaS delivery, API management, and enterprise IT infrastructure.

Legal Representation

Plaintiff’s Counsel: Isaac Phillip Rabicoff of **Rabicoff Law LLC** — a firm with a notable volume practice in patent assertion litigation, frequently active in the Eastern District of Texas.

Defendant’s Counsel: Gilbert Andrew Greene of **Duane Morris, LLP** — a major international law firm with deep IP litigation capabilities, well-positioned to mount robust patent defenses.

Litigation Timeline & Procedural History

The case was filed in the **Eastern District of Texas**, a venue historically favored by patent plaintiffs due to its plaintiff-friendly procedural reputation, experienced patent dockets, and established local patent rules.

The 35-day duration is remarkably short for patent litigation, which typically spans 18 to 36 months from filing to resolution in district court. The absence of any recorded claim construction proceedings, summary judgment motions, or Markman hearings in this timeframe indicates the case never advanced beyond its earliest procedural stage.

The Verdict & Legal Analysis

Outcome

The Court accepted and acknowledged xMatrix LLC’s **Notice of Voluntary Dismissal Without Prejudice** (Dkt. No. 9), formally closing the case. Key terms of the dismissal order include:

• All pending claims and causes of action **dismissed without prejudice**
• All pending relief requests **denied as moot**
• **Each party bears its own costs, expenses, and attorneys’ fees**

No damages were awarded. No injunctive relief was granted. Critically, dismissal **without prejudice** means xMatrix LLC retains the legal right to re-file claims against Vivion, Inc. on the same patent in the future, subject to applicable statutes of limitations and procedural constraints.

Verdict Cause Analysis

The case was terminated through **voluntary dismissal** under Rule 41(a)(1)(A)(i) — the most plaintiff-controlled exit mechanism in federal litigation. This provision allows a plaintiff to dismiss unilaterally before the defendant has served an answer or summary judgment motion, requiring no judicial approval beyond acknowledgment.

Because no merits-based ruling was issued, there is **no adjudication of patent validity, infringement, or claim construction**. The legal record is silent on whether Vivion contested infringement, raised invalidity defenses, or initiated inter partes review (IPR) proceedings at the USPTO — factors that frequently accelerate pre-answer settlements or strategic withdrawals.

Legal Significance

This case does not establish precedent on the merits of multi-services application gateway patent claims or the validity of US12300366B2. However, the rapid dismissal pattern is legally significant for several reasons:

• Patent remains enforceable: No invalidity ruling means US12300366B2 retains its full presumption of validity under **35 U.S.C. § 282**.
• Without-prejudice posture preserves optionality: xMatrix LLC can re-assert against Vivion or assert against other defendants in the same technology space.
• No claim construction record: Practitioners cannot draw interpretive guidance on the patent’s scope from this proceeding.
