Cedar Lane & Patent Armory v. Artec Europe: 3D Scanning Patents Dismissed Without Prejudice
Cedar Lane Technologies and Patent Armory jointly asserted two patents covering wireless 3D non-contact shape sensing against Artec Europe in the Eastern District of Texas. The case was voluntarily dismissed without prejudice after 512 days, leaving the door open for future proceedings and preserving both patents’ enforceability.
A 3D scanning patent dispute ends quietly — but not finally
On 29 August 2023, Cedar Lane Technologies, Inc. and co-plaintiff Patent Armory, Inc. filed suit in the Eastern District of Texas (Case No. 2:23-cv-00386) against Artec Europe, SARL, a Luxembourg-headquartered developer of professional 3D scanning hardware and software. The plaintiffs asserted two issued U.S. patents — US7256899B1 and US7336375B1 — both directed to wireless methods and systems for three-dimensional non-contact shape sensing, a core technology underpinning structured-light and photogrammetry-based 3D scanners.
On 22 January 2025, plaintiff Patent Armory, Inc. filed a Notice of Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), representing that the case was voluntarily dismissed without prejudice. The court accepted and acknowledged the notice, dismissed all pending claims and causes of action without prejudice, denied all remaining relief requests as moot, and directed the clerk to close the case. Each party was ordered to bear its own costs, expenses, and attorneys’ fees — a neutral cost allocation consistent with a pre-merits resolution.
The 512-day duration before dismissal is notable: it comfortably exceeds the timeframe typical of early-stage settlements or tactical withdrawals, suggesting the parties may have engaged in substantive claim construction exchanges or licensing negotiations before the plaintiffs elected to withdraw. The public record does not disclose whether a confidential settlement was reached. Because the dismissal carries no prejudice qualifier on the merits, the asserted patents remain fully enforceable and the plaintiffs retain the legal right to refile against Artec Europe or pursue other targets in the 3D scanning space.

Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(i) dismissal: no merits, no bar to refiling
A dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i) is a unilateral plaintiff right exercisable before the defendant serves an answer or a motion for summary judgment. It terminates the action procedurally without any adjudication on the merits. Crucially, ‘without prejudice’ means the plaintiffs are not barred from asserting the same patents against the same defendant in a future action, subject to applicable statutes of limitations.
No merits ruling issuedThe public record specifies without prejudice — but is silent on why
A ‘without prejudice’ dismissal preserves the plaintiff’s right to refile; a ‘with prejudice’ dismissal would function as a final judgment on the merits, barring future claims on the same patents against the same defendant. Here, the notice explicitly states without prejudice, and the court so ordered. The record does not disclose whether a confidential settlement, licensing agreement, or purely strategic decision drove the withdrawal — all three remain plausible explanations.
Refiling right preservedPatents survive: Cedar Lane and Patent Armory retain full enforcement rights
Because no validity or infringement determination was made, US7256899B1 and US7336375B1 emerge from this case with their legal presumption of validity intact. The plaintiffs can pursue Artec Europe again in a new action, assert the same patents against other 3D scanning competitors, or leverage the pending litigation history in licensing discussions. The cost neutrality order avoids any financial penalty for the withdrawal.
Enforcement rights intactArtec Europe escapes without a ruling — but faces residual patent risk
Artec Europe obtained no declaratory judgment of non-infringement or invalidity, meaning it carries no formal legal protection against a refiled suit on the same patents. The cost-neutral order provides no financial recovery for its defence expenditure over the 512-day period. Companies in the professional 3D scanning market should treat both asserted patents as live litigation risks and consider proactive freedom-to-operate or IPR strategies.

Official order — verbatim text
The court’s order tracks the precise language of Rule 41(a)(1)(A)(i), confirming dismissal as of right rather than by court discretion. The explicit ‘WITHOUT PREJUDICE’ designation is legally operative — it forecloses any argument that the dismissal constitutes a merits adjudication. The ‘DENIED AS MOOT’ disposition of pending relief requests confirms no substantive rulings were made. The cost-neutral instruction is standard for pre-answer voluntary dismissals and does not reflect a finding of bad faith or exceptional conduct by either party.
US7256899B1 & US7336375B1 — Wireless 3D Non-Contact Shape Sensing
US7256899B1 (application no. 11/538753) and US7336375B1 (application no. 11/757374) are issued U.S. patents covering wireless methods and systems for three-dimensional non-contact shape sensing. This technology domain underpins professional 3D scanning products that use structured light, photogrammetry, or similar non-contact techniques to capture precise geometric data of physical objects without physical probes. The wireless dimension of the claimed inventions is commercially significant — it encompasses untethered scanning workflows increasingly standard in industrial metrology and reverse engineering applications.
For the professional 3D scanner market — where Artec Europe competes directly with players such as FARO, Creaform, and Hexagon — these patents represent a potential cross-cutting risk. Any company whose products transmit 3D scan data wirelessly, or whose scanning workflow incorporates wireless sensor communication, should treat the claim scope of both patents as material to product design decisions. The patents’ survival through this litigation without a validity challenge creates a strengthened enforcement posture for subsequent licensing campaigns.
Should your product team run an FTO against US7256899B1 and US7336375B1?
If your organisation develops, manufactures, or distributes 3D scanning hardware or software — particularly systems that capture non-contact shape data wirelessly — these two patents warrant direct FTO attention. The plaintiffs have demonstrated willingness to litigate in E.D. Tex., and the without-prejudice dismissal keeps both patents live. Product teams building structured-light scanners, LIDAR platforms, photogrammetry systems, or wireless metrology tools should assess claim overlap before commercialisation or market expansion.

What this case signals for the 3D scanning and spatial sensing IP landscape
Two wireless 3D sensing patents remain live enforcement tools after a 512-day Eastern District of Texas campaign against a leading scanner manufacturer.
E.D. Tex. remains a preferred venue for 3D sensing patent assertions
The Eastern District of Texas continues to attract patent assertion cases in hardware-adjacent technology domains. Filing in E.D. Tex. and voluntarily dismissing without prejudice is a known portfolio-leverage tactic — the filing alone can catalyse licensing dialogue. Companies commercialising 3D scanning or structured-light sensing technology should maintain active docket monitoring for both asserted patents.
A neutral cost order signals no clear winner — and signals possible deal
Courts in E.D. Tex. routinely attach the ‘each party bears its own costs’ language to voluntary dismissals. Where a confidential settlement has been reached, this framing is standard. The 512-day elapsed time before dismissal is consistent with a licensing negotiation that ran to conclusion — positive or negative — rather than an early tactical retreat. The absence of fee-shifting under 35 U.S.C. § 285 suggests no exceptional case finding was at risk.
Cedar v Artec — key questions answered
The case was voluntarily dismissed without prejudice on 22 January 2025, after 512 days of litigation. Plaintiff Patent Armory filed a Rule 41(a)(1)(A)(i) notice of dismissal. The court accepted the notice, dismissed all claims without prejudice, and ordered each party to bear its own costs. No merits ruling was issued.
Two U.S. patents were asserted: US7256899B1 (application 11/538753) and US7336375B1 (application 11/757374). Both cover wireless methods and systems for three-dimensional non-contact shape sensing — technology directly relevant to professional 3D scanning products.
Yes. A dismissal without prejudice under Rule 41(a)(1)(A)(i) does not constitute a merits adjudication and does not bar the plaintiffs from refiling claims based on the same patents against Artec Europe or other defendants, subject to applicable statutes of limitations and the IPR one-year bar from any new complaint service date.
The public record does not confirm or deny a settlement. The voluntary dismissal notice, cost-neutral order, and 512-day duration before withdrawal are all consistent with a confidential licensing agreement having been reached, but that remains speculative based on publicly available court documents alone.
E.D. Tex. is a historically plaintiff-friendly patent venue with experienced patent dockets and established local rules. Patent assertion entities frequently file there to leverage procedural familiarity and litigation cost asymmetry. The filing of this case in E.D. Tex. is consistent with a portfolio licensing strategy targeting professional 3D scanning manufacturers.
