VDPP, LLC v. Qualcomm, Inc.: Voluntary Dismissal Without Prejudice After 224 Days
VDPP, LLC filed suit against semiconductor giant Qualcomm in the Western District of Texas asserting US10021380B1, covering faster state transitioning for continuous adjustable 3Deeps filter spectacles. The case closed after 224 days via voluntary dismissal without prejudice before Qualcomm answered, leaving the patent’s enforceability intact for future assertions.
Pre-Answer Dismissal Keeps 3D Spectacles Patent Live Against Qualcomm
On July 31, 2024, VDPP, LLC — a patent assertion entity — filed an infringement action against Qualcomm, Inc. in the Western District of Texas before Judge Alan D. Albright. The asserted patent, US10021380B1, covers faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials, a technology with potential relevance to display, imaging, and wearable visual processing systems where Qualcomm’s chipsets or processing components may play a role.
The case closed on March 12, 2025, when VDPP filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss without a court order when the defendant has not yet answered or filed a motion for summary judgment. The dismissal was expressly specified as without prejudice as to the asserted patent, meaning VDPP retains the right to re-file suit on US10021380B1 against Qualcomm or other parties. Each party was ordered to bear its own costs and attorneys’ fees.
The 224-day duration and pre-answer timing suggest the parties may have engaged in early-stage negotiations or that VDPP reassessed its litigation posture following case initiation — though the public record does not disclose any settlement or licensing terms. The without-prejudice designation is commercially significant: it preserves VDPP’s optionality and signals this patent may be deployed again. What remains unknown is whether any parallel licensing discussions occurred or whether claim scope concerns informed the early exit.

Voluntarily dismissed without prejudice: what the terms mean for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit before answer
Federal Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order — and as of right — before the defendant has served an answer or a motion for summary judgment. Qualcomm had not done either, so VDPP could exit unilaterally. The court itself need not approve. This is the most procedurally straightforward dismissal mechanism available and carries no merits adjudication.
No merits rulingWithout prejudice: the patent remains a live litigation asset
VDPP expressly specified the dismissal is without prejudice as to the asserted patent. This means no judgment was entered against VDPP and the claims were not adjudicated. VDPP may refile suit on US10021380B1 against Qualcomm or any other party, subject to applicable statutes of limitations. A with-prejudice dismissal would have barred re-filing against Qualcomm; that outcome did not occur here.
Patent remains assertableQualcomm exits without a formal win — or any binding protection
While Qualcomm avoids an adverse judgment, it also obtains no invalidity ruling, no non-infringement finding, and no covenant not to sue from this dismissal. The without-prejudice nature of the exit means Qualcomm could face the same patent assertion again. Qualcomm’s legal spend was incurred without a dispositive outcome, and Baker Botts LLP’s involvement suggests a full defense posture was mobilised.
No binding protection for QualcommPre-answer exit is consistent with a monetisation or licensing strategy
PAEs operating in the W.D. Texas ecosystem frequently use early dismissal without prejudice as a tactical tool — either after extracting a licensing agreement (not disclosed here) or to reposition before discovery costs mount. VDPP’s retention of Ramey LLP, a prolific PAE-focused firm, and the without-prejudice terms together suggest US10021380B1 may be a recurring assertion vehicle. Companies in the display, wearables, and imaging processing sectors should monitor this patent.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly states the dismissal is without prejudice as to the asserted patent — language that carries material legal significance. No merits determination was made: there is no finding of infringement, non-infringement, or invalidity. The explicit ‘without prejudice’ designation preserves VDPP’s right to reassert US10021380B1, distinguishing this outcome from a with-prejudice dismissal that would bar re-filing against Qualcomm. The mutual cost-bearing provision forecloses any fee-shifting claim under 35 U.S.C. § 285.
US10021380B1 — Faster State Transitioning for 3Deeps Filter Spectacles
US10021380B1 protects technology relating to faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials. The patent was filed under application number US15/907614 and issued to VDPP, LLC. It sits at the intersection of display optics and wearable visual technology — covering methods and materials that enable more rapid switching between tint states in 3D eyewear, a function relevant to both traditional stereoscopic 3D and emerging adaptive display systems.
Strategically, this patent’s value lies in its potential applicability to components and processing systems that control display state transitions in wearable and immersive visual devices — an area where Qualcomm’s Snapdragon XR platform and display driver technologies are commercially significant. As AR and VR hardware proliferates, patents covering optical state control and variable tint materials may attract increasing assertion activity. Companies developing smart eyewear, heads-up displays, or display-adjacent chips should monitor US10021380B1 closely given VDPP’s without-prejudice exit.
Should you run an FTO analysis against US10021380B1?
Any company developing products that involve dynamic optical state control, variable tint lenses, or display systems integrated into wearable visual devices should consider a freedom-to-operate review against US10021380B1. The patent’s without-prejudice dismissal against Qualcomm means it is actively available for re-assertion. AR/VR hardware makers, smart eyewear developers, display driver IC companies, and ODMs supplying optical components to these markets face non-trivial exposure if their products read on the claims.

What this case signals for the 3D display and imaging IP landscape
A without-prejudice exit in W.D. Texas before answer is rarely the end of the story — particularly for PAE-held display and processing patents.
Without-prejudice dismissals from PAEs often precede re-assertion or licensing
When a PAE dismisses without prejudice before the defendant answers, it typically signals either an early licensing resolution (undisclosed) or a tactical retreat to refile with stronger claim charts. US10021380B1 remains a live threat. Companies whose products intersect with variable tint display processing or wearable visual technology should treat this case as an open signal, not a closed chapter.
Judge Albright’s docket: early exits reflect W.D. Texas litigation dynamics
The Western District of Texas under Judge Albright is a high-volume patent litigation venue. Pre-answer voluntary dismissals on his docket are not uncommon and often reflect plaintiff-side recalibration after initial case assessment. The absence of any IPR or inter partes review filing against US10021380B1 in the public record may be relevant for future defendants evaluating their response options.
VDPP v Qualcomm — key questions answered
The dismissal without prejudice means no merits ruling was issued and VDPP retains the right to refile suit on US10021380B1 against Qualcomm or other defendants. Under Rule 41(a)(1)(A)(i), VDPP could dismiss unilaterally because Qualcomm had not yet answered. Qualcomm received no invalidity finding or covenant not to sue.
VDPP asserted US10021380B1 (application number US15/907614), covering faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials. The patent relates to dynamic optical state control in wearable 3D eyewear systems.
VDPP was represented by William P. Ramey III of Ramey LLP, a firm with an extensive PAE-focused patent litigation practice in W.D. Texas. Qualcomm was represented by Douglas M. Kubehl, Ellyar Yousef Barazesh, and Emily F. Deer of Baker Botts LLP.
Yes. The dismissal was expressly without prejudice as to the asserted patent. VDPP may refile an action asserting US10021380B1 against Qualcomm, subject to applicable statutes of limitations. A second voluntary dismissal against the same defendant on the same claims would, however, operate as a dismissal with prejudice under Rule 41(a)(1)(B).
The dismissal notice specifies that each party shall bear its own costs, expenses, and attorneys’ fees. This mutual cost-bearing arrangement forecloses any subsequent fee-shifting application under 35 U.S.C. § 285, which would require a finding that the case is exceptional. No such finding was made.
