Case Overview
The Parties
⚖️ Plaintiff
Patent assertion entity (PAE) that holds and licenses intellectual property in consumer and commercial electronics, active in asserting wireless communication patents across multiple proceedings.
🛡️ Defendant
New York-based manufacturer and supplier of rugged mobile computers and barcode scanners, primarily serving enterprise customers in logistics, healthcare, and retail sectors.
Patents at Issue
This case centered on U.S. Patent No. 9,031,537 B2, covering multi-standard wireless communication technology embedded in handheld electronic devices. The patent protects the ornamental appearance rather than functional technology.
- • US 9,031,537 B2 — Multi-standard wireless communication in handheld electronic devices. It covers devices incorporating a microprocessor and multiple wireless transceiver modules for cellular (GSM, CDMA, GPRS, 3G), Wi-Fi (IEEE 802.11), and short-range technologies (Bluetooth, infrared, RFID).

The Verdict & Legal Analysis
Outcome
Mesa Digital, LLC voluntarily dismissed all claims against Janam Technologies, LLC without prejudice on January 6, 2026, pursuant to **Federal Rule of Civil Procedure 41(a)(1)(A)(i)**. No damages were awarded, and no injunctive relief was granted. The court issued no merits ruling on patent validity or infringement.
Key Legal Issues
The procedural vehicle here — Rule 41(a)(1)(A)(i) — permits a plaintiff to dismiss an action as a matter of right, without a court order, before the opposing party serves an answer or a motion for summary judgment. This is among the simplest and cleanest exits available in federal civil litigation. Because the court never ruled on the merits, there is no judicial finding regarding the validity of US 9,031,537 B2, whether Janam’s products infringe any asserted claims, claim construction of any disputed terms, damages, or willfulness.
A “without prejudice” dismissal is legally significant: Mesa Digital retains the right to refile the same claims against Janam in the future, provided the applicable statute of limitations has not expired. However, the “two-dismissal rule” under Rule 41(a)(1)(B) is worth noting: a second voluntary dismissal of the same claim operates as an adjudication on the merits. Mesa Digital would face this constraint if it refiles and again seeks voluntary dismissal.

✅ Key Takeaways
Rule 41(a)(1)(A)(i) remains a powerful pre-answer exit tool, but the two-dismissal rule creates a hard stop on repeat use against the same defendant on the same claims.

US Patent No. 9,031,537 B2 (Application No. US 12/257,205), covering electronic wireless handheld devices with multiple transceiver modules supporting cellular, Wi-Fi, Bluetooth, infrared, and RFID communication standards.
Plaintiff Mesa Digital, LLC filed a voluntary notice of dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i), before Janam Technologies filed any answer or summary judgment motion. No court order was required.
Yes. A without-prejudice dismissal preserves the plaintiff’s right to refile the same claims. However, a subsequent voluntary dismissal would trigger the two-dismissal rule and operate as an adjudication on the merits under Rule 41(a)(1)(B).
