WirelessWerx IP v. Trimble — Voluntary Dismissal Without Prejudice in 70 Days
WirelessWerx IP, LLC brought a patent infringement action against precision technology company Trimble, Inc. in the Colorado District Court, asserting US8290515B2 covering wireless device monitoring and control systems. The case was voluntarily dismissed without prejudice after just 70 days, before Trimble filed any answer or dispositive motion, with each party bearing its own costs.
Early voluntary exit: WirelessWerx preserves its litigation options against Trimble
On April 17, 2024, WirelessWerx IP, LLC filed a patent infringement complaint against Trimble, Inc. in the U.S. District Court for the District of Colorado, asserting U.S. Patent No. 8,290,515 B2. The patent relates to methods and systems for monitoring and controlling devices using wireless media — a technology domain directly relevant to Trimble’s positioning, telematics, and field connectivity product lines. WirelessWerx was represented by William P. Ramey III of Ramey LLP; Trimble retained Amanda J. Tessar of Perkins Coie LLP.
The action concluded on June 26, 2024, when WirelessWerx filed a notice of voluntary dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), explicitly specifying that the dismissal is without prejudice as to the asserted patent. Trimble had not yet filed an answer or a motion for summary judgment at the time of dismissal, which is the procedural prerequisite that makes a unilateral Rule 41(a)(1)(A)(i) dismissal available to the plaintiff as of right. Each party was ordered to bear its own costs, expenses, and attorneys’ fees.
The 70-day duration and pre-answer timing suggest the parties may have reached an informal resolution, licensing arrangement, or WirelessWerx may have reassessed its litigation strategy — though none of these explanations can be confirmed from the public record. Critically, the without-prejudice designation means US8290515B2 remains a live enforcement asset: WirelessWerx is not barred from reasserting this patent against Trimble or pursuing it against other defendants in the wireless device monitoring and control space.

70 days — resolved well before the typical 18–24 month district court patent trial cycle
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss before defendant answers
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. Because Trimble had not yet done either, WirelessWerx exercised this right unilaterally. The dismissal carries no merits adjudication — no court ruled on infringement, validity, or claim scope.
No merits rulingWithout prejudice: the patent stays live for future enforcement
The notice expressly states the dismissal is without prejudice as to the asserted patent. This is legally significant: WirelessWerx retains the right to refile the same infringement claims against Trimble or any other party at a future date. A dismissal with prejudice would have permanently extinguished the claims. The public record confirms without prejudice status here — this is not ambiguous.
Patent remains enforceableTrimble escapes judgment — but faces potential refiling risk
Trimble secured an exit from this specific action without any adverse finding. However, because the dismissal is without prejudice, Trimble cannot treat this as a clean resolution. WirelessWerx retains the option to refile in Colorado or another jurisdiction. Trimble’s legal team at Perkins Coie likely preserved early invalidity and non-infringement positions that would carry strategic value if the case is refiled.
No preclusive effectWireless device monitoring IP remains an active enforcement risk in the sector
US8290515B2 covering wireless device monitoring and control methods is asserted by a dedicated patent licensing entity. The early dismissal without prejudice — combined with no costs award against WirelessWerx — suggests this patent is likely to reappear in enforcement activity. Companies operating in telematics, IoT device management, and field connectivity should treat this patent as a continuing watch item.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly designates the outcome as without prejudice as to the asserted patent. This phrasing is deliberate and consequential: it preserves WirelessWerx’s full enforcement rights under US8290515B2. The costs-neutrality provision — each party bears its own fees — is standard for pre-answer voluntary dismissals and does not imply any negotiated payment. No merits determination was made.
US8290515B2 — Wireless device monitoring and control method and system
U.S. Patent No. 8,290,515 B2, filed under application number 12/948,692, covers methods and systems for monitoring and controlling devices utilizing wireless media. The patent sits at the intersection of wireless communications and device management — a broad technical domain that spans industrial IoT, telematics, fleet management, and field connectivity systems. The application’s filing date context places it in the early smartphone and machine-to-machine communications era, potentially yielding broad claim scope over wireless control architectures that have since become standard.
For companies like Trimble — whose product portfolio spans GPS-based field devices, telematics hardware, and connected construction and agriculture equipment — a patent asserting wireless device monitoring and control methods represents a plausible surface area for infringement claims across multiple product lines. As a patent held by a dedicated assertion entity with no apparent operating business, US8290515B2 carries the characteristic risk profile of a PAE asset: no cross-licensing leverage for the defendant, and a licensor with strong incentive to pursue royalties rather than injunctive relief.
Should you run an FTO against US8290515B2?
Any company developing or commercialising wireless device monitoring systems, IoT device management platforms, telematics hardware, or remote control infrastructure should assess exposure to US8290515B2. The patent’s claims around wireless media-based device monitoring and control could map to a wide range of connectivity products. Given that the patent has not been tested on validity or claim scope in litigation, the uncertainty is elevated — making a proactive FTO analysis particularly valuable before scaling a relevant product.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map US8290515B2’s claim language against your specific product architecture, identify prior art that could support invalidity arguments, and benchmark against other PAE assertions in the wireless device management space.

What this case signals for the wireless device monitoring IP landscape
A pre-answer voluntary dismissal without prejudice is rarely the end of the story for a patent assertion entity — it often signals a strategic reset.
Pre-answer dismissals by PAEs typically precede refiling or parallel campaigns
When a patent assertion entity voluntarily dismisses without prejudice before the defendant answers, it frequently indicates ongoing licensing negotiations, a venue or defendant recalibration, or preparation for a broader multi-defendant campaign. The public record here does not confirm any of these, but the pattern is consistent with PAE enforcement strategy. Competitors of Trimble in the telematics and wireless control space should treat this as a potential precursor to broader activity.
US8290515B2 has not been tested on the merits — validity is an open question
Because the case ended before Trimble answered, no invalidity defenses, claim construction arguments, or IPR petitions have been publicly tested against US8290515B2. Any company in the wireless device monitoring or IoT connectivity sector that receives a demand letter citing this patent faces an untested enforcement vehicle — making early prior art searches and FTO analysis especially important.
WirelessWerx v Trimble — key questions answered
The dismissal without prejudice means WirelessWerx retains all rights to refile infringement claims based on US8290515B2 against Trimble or any other party. No court ruled on the merits of infringement or validity. The case ended under Rule 41(a)(1)(A)(i), which allows a plaintiff to dismiss unilaterally before the defendant files an answer or summary judgment motion.
US8290515B2 covers a method and system for monitoring and controlling devices using wireless media. Filed under application 12/948,692, it addresses wireless device management architectures relevant to IoT, telematics, fleet management, and connected field devices. It is held by WirelessWerx IP, LLC, a patent assertion entity with no apparent operating product business.
The public record does not disclose the reason. The 70-day timeline and pre-answer timing are consistent with several possibilities: informal settlement, a licensing agreement, a strategic decision to refile in a different jurisdiction, or an assessment that Trimble’s defense posture made the case difficult to pursue. None of these can be confirmed from the available filings.
No. A dismissal without prejudice carries no preclusive effect. WirelessWerx is legally free to refile the same claims against Trimble in the future, subject only to applicable statutes of limitations and any private agreement between the parties that is not reflected in the public record. Trimble should treat US8290515B2 as an ongoing watch item.
The case was filed and dismissed in the U.S. District Court for the District of Colorado (Case No. 1:24-cv-01035). The voluntary dismissal notice expressly states each party shall bear its own costs, expenses, and attorneys’ fees. No fee-shifting under 35 U.S.C. § 285 or other provision was ordered, which is typical for pre-answer voluntary dismissals that resolve before any substantive motion practice.
