ContactWave LLC vs. Nordstrom: Voluntary Dismissal in Messaging Patent Dispute

Case Overview

In a case that underscores the strategic complexities of patent assertion in the retail technology sector, ContactWave LLC’s infringement action against Nordstrom, Inc. concluded with a voluntary dismissal with prejudice — a resolution carrying significant implications for how patent holders and accused infringers navigate messaging technology disputes. Filed on December 2, 2024, in the Texas Eastern District Court and closed January 9, 2026, Case No. 2:24-cv-00993 centered on U.S. Patent No. 9,531,665 B2, covering an information messaging system technology. The case lasted 403 days before Plaintiff ContactWave LLC elected to exit the litigation entirely, bearing its own costs under the court’s acceptance of its Rule 41(a)(1)(A)(i) notices. For patent attorneys monitoring information messaging patent infringement trends, IP professionals assessing assertion strategies, and R&D teams evaluating freedom-to-operate risk in communication technology, this outcome provides a textbook example of how patent litigation can resolve before reaching adjudication on the merits.

The Parties

The Patent at Issue

This case centered on **U.S. Patent No. 9,531,665 B2** (application number US14/618541), covering an information messaging system. Messaging system patents of this type typically address methods and systems for routing, managing, or delivering messages across networked platforms, often capturing broad commercial applicability across retail notification systems, CRM integrations, and customer-facing communication tools.

The Verdict & Legal Analysis

Outcome

The case concluded with **voluntary dismissal with prejudice** pursuant to **Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure**. The Court accepted and acknowledged both Notices of Dismissal filed by ContactWave LLC. Critically, the dismissal was entered **with prejudice**, meaning ContactWave is permanently barred from re-filing the same infringement claims against Nordstrom on U.S. Patent No. 9,531,665 B2. No damages were awarded. No injunctive relief was granted. Each party was ordered to **bear its own costs, expenses, and attorneys’ fees** — a standard allocation in plaintiff-initiated voluntary dismissals at this stage of litigation.

Verdict Cause Analysis

The infringement action was initiated under standard patent infringement claims, but the case never reached a published Markman ruling, summary judgment disposition, or trial verdict based on the available record. The voluntary dismissal with prejudice is itself a legally significant procedural outcome. Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss without court order before the opposing party serves an answer or motion for summary judgment. However, the docket’s reference to Dkt. Nos. 53 and 54 as the dismissal filings indicates substantial prior activity in the case, suggesting the dismissal occurred after meaningful litigation exchange — including, potentially, defendant’s responsive pleadings, discovery disputes, or claim construction briefing.

The decision to dismiss **with prejudice** rather than without prejudice is particularly notable. Without prejudice dismissals preserve the plaintiff’s right to refile; a with-prejudice exit permanently extinguishes those claims. This distinction suggests either a negotiated resolution between the parties (details undisclosed), a strategic reassessment of claim strength following early litigation developments, or a settlement agreement whose terms are confidential.

Legal Significance

For information messaging patent litigation broadly, this outcome reinforces several key principles. First, **venue selection in the Eastern District of Texas** alone does not guarantee resolution favorable to patent asserters — defendants with experienced Texas-based counsel can effectively mount early-stage defenses that prompt plaintiff reassessment. Second, the **with-prejudice nature** of the dismissal creates a permanent bar, conferring meaningful finality on Nordstrom’s position regarding this specific patent. Third, the case illustrates how **multi-case assertion strategies** (Lead and Member Cases) can be efficiently resolved through coordinated dismissal filings.
