VDPP, LLC v. Dell Technologies: 3D Spectacles Patent Dismissed With Prejudice
VDPP, LLC asserted US10021380B1 — covering faster state transitioning for variable-tint 3D filter spectacles — against Dell Technologies in the Western District of Texas. The plaintiff voluntarily dismissed the case with prejudice just 111 days after filing, before Dell served an answer or summary judgment motion.
Pre-answer voluntary dismissal bars VDPP from refiling against Dell
VDPP, LLC filed suit against Dell Technologies, Inc. on July 31, 2024, in the Western District of Texas (Case No. 7:24-cv-00180), asserting infringement of US10021380B1. The patent relates to faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials — a technology with applications in display and visual computing hardware. Dell was represented by Barry K. Shelton of Shelton Coburn LLP; VDPP by William P. Ramey III of Ramey LLP, a firm with a substantial track record in patent assertion matters.
On November 15, 2024 — 107 days after filing — VDPP filed a Notice of Voluntary Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Dell had not yet served an answer or a motion for summary judgment, the notice was self-effectuating: no court order was required to terminate the case. The court confirmed the dismissal on November 19, 2024, and ordered each party to bear its own costs and attorney fees. The with-prejudice designation means VDPP is permanently barred from reasserting the same claims against Dell on US10021380B1.
The 111-day lifespan of this case — ending before any substantive briefing — is consistent with a pre-litigation settlement, a licensing resolution, or a strategic reassessment of claim viability. The public record does not disclose whether any commercial agreement was reached between the parties. The with-prejudice election is notable: a without-prejudice dismissal would have preserved refiling rights, suggesting VDPP had reason to accept finality, though the precise driver remains unknown from available docket information.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) — self-effectuating, no court order needed
A plaintiff may voluntarily dismiss an action as of right by filing a notice before the defendant serves an answer or summary judgment motion. The dismissal is immediate and automatic — no judicial approval is required. Because VDPP elected with-prejudice, the action is treated as a final adjudication on the merits, permanently extinguishing VDPP’s ability to refile the same claims against Dell on this patent.
Rule 41(a)(1)(A)(i) — self-effectuatingWith prejudice locks the door — VDPP cannot refile against Dell
A voluntary dismissal without prejudice would have preserved VDPP’s right to refile against Dell in a future action. The with-prejudice election forecloses that option entirely, functioning as a final judgment on the merits for res judicata purposes. The public record does not disclose what drove VDPP to accept this finality — it may reflect a settlement, a licensing deal, or a reassessment of infringement or claim scope — but the legal consequence is clear: these claims against Dell are permanently extinguished.
Permanent bar on refilingDell exits with no liability and no fee award
Dell Technologies avoided any infringement finding, claim construction proceeding, or damages exposure. The court’s order that each party bear its own costs means Dell received no fee-shifting award despite the early exit — consistent with the default Rule 41 approach when dismissal precedes any substantive litigation. Dell’s lack of an answer or summary judgment motion confirms the case was resolved at the earliest procedural stage, minimising litigation spend.
No liability, own costsUS10021380B1 remains live — third-party exposure persists
A with-prejudice dismissal resolves only VDPP’s claims against Dell. The patent US10021380B1 remains in force and VDPP retains the right to assert it against other display hardware or 3D technology vendors. Companies in the visual computing, AR/VR headset, and 3D display supply chain should treat this outcome as a signal that the patent is actively being enforced, even though Dell has exited the dispute.

Official order — verbatim text
The court’s order reflects the purely procedural nature of this termination: because Dell had not served an answer or summary judgment motion, VDPP’s notice of voluntary dismissal was self-effectuating under Rule 41(a)(1)(A)(i) — no judicial merits determination was made. The with-prejudice designation carries the legal weight of a final judgment for res judicata purposes, but it does not constitute any finding of infringement, invalidity, or claim scope. The fee neutrality order — each party bearing its own costs — is the default outcome at this stage and does not signal fault or bad faith by either party.
US10021380B1 — faster state transitioning for variable-tint 3D filter spectacles
US10021380B1 protects methods and systems for faster state transitioning in continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials. The patent’s application number is US15/907614. The technology addresses a core engineering challenge in active-filter 3D eyewear: the speed and precision with which lenses can shift between tint states to synchronise with display frame rates. Multi-layered variable tint materials are central to the claimed approach, distinguishing it from single-layer or passive filter architectures common in earlier 3D glasses.
Strategically, US10021380B1 sits at the intersection of display hardware, wearable optics, and AR/VR device design — all high-growth sectors. As display refresh rates climb and adaptive eyewear enters mainstream consumer and professional markets, patents covering tint-state switching speed become increasingly relevant to OEM design freedom. The assertion against Dell — a major display and computing hardware vendor — suggests VDPP views the patent as covering commercially deployed products, not merely academic implementations. Any company developing adaptive-filter eyewear, AR headsets, or variable-tint optical components should assess their design-around options relative to this patent’s claim scope.
Should you run an FTO analysis against US10021380B1?
If your product roadmap includes variable-tint eyewear, adaptive optical filters, multi-layered lens assemblies, or active 3D display systems, US10021380B1 warrants a targeted freedom-to-operate review. VDPP’s willingness to assert this patent against a major OEM like Dell — and to reach apparent resolution within 111 days — confirms active monetisation. R&D teams developing next-generation AR/VR headsets or smart eyewear should map their state-transitioning mechanisms against the patent’s independent claims before product launch.
PatSnap Eureka’s FTO Search Agent can rapidly identify the claim boundaries of US10021380B1, surface prior art that may limit its scope, and flag design-around opportunities in the variable-tint and multi-layered filter technology space. Eureka’s portfolio analytics also reveal whether VDPP holds continuation or related patents that could extend assertion risk beyond this single grant — critical intelligence for any IP clearance opinion in the adaptive optics and 3D display sector.

What this case signals for the 3D display and visual computing IP landscape
A pre-answer dismissal with prejudice in 111 days raises pointed questions for any company commercialising variable-tint or adaptive-filter display technology.
Pre-answer resolution signals a likely licensing or commercial agreement
Cases dismissed with prejudice this early — before any answer, claim construction, or IPR filing — typically suggest the parties reached a commercial resolution. Whether that is a licence, a cross-licence, or a covenant not to sue, the effect for Dell is the same: finality. Competitors should note that VDPP’s assertion strategy appears to target major OEMs directly.
US10021380B1 remains a live enforcement risk for the broader display sector
This dismissal does not retire the patent. VDPP retains enforcement rights against any other party making or selling products potentially covered by US10021380B1. Companies in AR/VR hardware, adaptive eyewear, or multi-layered variable-tint display systems should treat this case as a canary: the patent is being actively monetised.
VDPP v Dell — key questions answered
The with-prejudice dismissal permanently bars VDPP from asserting the same claims in US10021380B1 against Dell Technologies. For res judicata purposes it operates as a final adjudication on the merits. VDPP retains all rights to enforce the patent against third parties.
No validity determination was made. The case was voluntarily dismissed before Dell filed an answer or any substantive motion. The patent’s validity was never adjudicated, meaning it remains presumptively valid and enforceable against the broader market.
The public record is silent on the precise reason. The with-prejudice election is consistent with a confidential settlement or licensing agreement — as it gives Dell permanent finality in exchange for VDPP accepting closure of this specific action. A without-prejudice dismissal would have preserved VDPP’s refiling rights and is more typical of pure strategic withdrawal.
Rule 41(a)(1)(A)(i) allows a plaintiff to voluntarily dismiss an action as of right — without court approval — by filing a notice before the defendant serves an answer or summary judgment motion. Because Dell had not yet served either, VDPP’s notice was self-effectuating under Fifth Circuit precedent, automatically terminating the case the moment it was filed.
No. The dismissal resolves only VDPP’s claims against Dell. US10021380B1 remains an active, enforceable patent. VDPP can assert it against any other entity whose products may infringe the patent’s claims. Companies in the adaptive optics, AR/VR eyewear, and 3D display hardware sectors should treat this enforcement action as evidence of active patent monetisation and conduct appropriate FTO analysis.
