VDPP LLC v. JVC Kenwood: Infringement Suit Dismissed Without Prejudice
VDPP, LLC filed suit against JVC Kenwood Corp. in the Central District of California alleging infringement of two patents covering variable-tint 3D display filter spectacles technology. The case closed after 213 days via voluntary dismissal without prejudice under Rule 41, before JVC Kenwood filed any answer or dispositive motion.
Early voluntary exit preserves VDPP’s right to refile against JVC Kenwood
On 8 March 2024, VDPP, LLC — a patent assertion entity represented by Ramey LLP — filed suit against JVC Kenwood Corp. in the U.S. District Court for the Central District of California (Case No. 2:24-cv-01881). The complaint asserted infringement of two patents: US10021380B1 and US9948922B2, both directed to technology described as continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials — a niche domain within 3D display and eyewear systems.
The case closed on 7 October 2024, just 213 days after filing, when VDPP filed a notice of voluntary dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Critically, the dismissal was expressly stated to be WITHOUT PREJUDICE as to the asserted patents, and each party was directed to bear its own costs, expenses, and attorneys’ fees. Because JVC Kenwood had not yet answered or filed a motion for summary judgment, VDPP was entitled as of right to dismiss unilaterally under Rule 41(a)(1)(A)(i) — no court order was required.
The resolution timeline is consistent with a pre-answer negotiation or strategic reassessment by the plaintiff. The absence of any responsive filing from JVC Kenwood and the without-prejudice designation leaves the public record silent on whether a settlement or license was reached, or whether VDPP simply elected to withdraw and preserve optionality. The without-prejudice dismissal means JVC Kenwood has not obtained any immunity from future suit on these patents, and VDPP retains the ability to reassert the same claims.

Voluntarily dismissed: what Rule 41 without prejudice means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to dismiss
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 before the defendant serves an answer or a motion for summary judgment. Because JVC Kenwood had not done either, VDPP exercised this right unilaterally. No judicial approval was needed, and the dismissal took immediate effect on filing.
No court order requiredWithout prejudice: the public record does not confirm a settlement
A dismissal ‘without prejudice’ means the claims are not adjudicated on the merits and VDPP is not barred from refiling the same patent claims against JVC Kenwood in future. A ‘with prejudice’ dismissal would extinguish those rights permanently. The notice expressly states ‘WITHOUT PREJUDICE’ — but the public record is silent on whether a licensing deal or other commercial resolution underlies the withdrawal. Both possibilities remain consistent with the available docket information.
Refile rights preservedJVC Kenwood exits without a merits ruling — but carries residual exposure
JVC Kenwood avoids an infringement finding and incurs no fee award under the dismissal terms. However, without a declaratory judgment of invalidity or non-infringement, the company holds no formal legal shield against reassertion of US10021380B1 or US9948922B2. The pre-answer posture suggests JVC Kenwood’s litigation spend was minimal, but the underlying patent risk persists until the patents expire or are invalidated.
No immunity from reassertionVariable-tint 3D display IP remains live and unresolved in the market
The without-prejudice exit leaves VDPP’s patent portfolio intact and potentially active against other players in 3D display, eyewear, and consumer electronics. Competitors in multi-layered variable tint or 3D filter spectacles technology should note that no claim construction or invalidity ruling has emerged from this case to limit the patents’ scope. The sector-specific IP risk signalled by this filing has not been extinguished.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly designates the dismissal as WITHOUT PREJUDICE, with each party bearing its own costs. This phrasing is legally precise: no merits adjudication occurred, no infringement or invalidity determination was made, and VDPP retains full standing to reassert US10021380B1 and US9948922B2 against JVC Kenwood or any third party. The mutual cost-bearing clause further suggests the parties reached no court-supervised agreement — though a private commercial arrangement cannot be ruled out from the public record alone.
US10021380B1 & US9948922B2 — Variable-tint 3D filter spectacles technology
US10021380B1 (application US15/907614) and US9948922B2 (application US15/683623) both relate to what the asserted product description characterises as ‘continuous adjustable 3Deeps filter spectacles’ — eyewear incorporating multi-layered variable tint materials capable of rapid state transitions. This technology sits at the intersection of active eyewear, display filtering, and materials science, with potential relevance to 3D cinema, gaming, and emerging mixed-reality display systems. Both patents issued as granted US utility patents, conferring standard 20-year term exclusivity from their respective effective filing dates.
For consumer electronics OEMs and display technology companies, the breadth of claims covering state-transitioning variable tint materials — if construed broadly — could implicate a range of products beyond traditional 3D glasses, including smart eyewear accessories and variable-opacity lens systems. VDPP’s decision to assert both patents simultaneously against JVC Kenwood, a maker of audio-visual equipment, suggests the patent holder views the portfolio as relevant to display-adjacent electronics product lines. No claim construction ruling exists from this case to narrow or clarify that scope.
Should your product team run an FTO against US10021380B1 and US9948922B2?
Any company designing, manufacturing, or importing products involving variable-tint optical elements, active 3D filter spectacles, or multi-layer lens state-switching mechanisms should treat these two patents as live FTO risks. Because no invalidity ruling or claim construction order emerged from this case, the patents’ full claimed scope remains untested in adversarial proceedings. JVC Kenwood’s exit without a merits defence means there is no public prior art or prosecution record analysis to leverage as a free rider.
PatSnap Eureka’s FTO Search Agent can map the claim language of US10021380B1 and US9948922B2 against your product specifications, surface the prosecution history of the US15/907614 and US15/683623 applications to identify potential estoppel arguments, and flag related VDPP or continuation filings that may extend the enforcement window. Running an FTO now — before a demand letter arrives — positions your team to respond from a position of prepared analysis rather than reactive urgency.

What this case signals for the 3D display and consumer electronics IP landscape
A pre-answer Rule 41 exit preserves maximum optionality for VDPP while leaving JVC Kenwood and sector peers without a definitive claim scope ruling.
Without-prejudice exits are a hallmark of PAE licensing strategy
Ramey LLP — counsel for VDPP — has filed numerous patent suits that resolve at the pre-answer stage. This pattern is consistent with a demand-letter-to-litigation funnel designed to prompt licensing discussions. Companies that receive pre-suit communications on these patents should assess the demand carefully before litigation costs accumulate.
JVC Kenwood’s no-answer posture limits public intelligence on the defence position
Because JVC Kenwood filed no answer, counterclaims, or invalidity contentions, no prior art or claim construction arguments entered the public record. This makes it harder for subsequent defendants or FTO analysts to predict how VDPP’s patents would fare under adversarial scrutiny — a deliberate structural advantage for the patent holder.
VDPP v JVC — key questions answered
VDPP, LLC filed a patent infringement suit against JVC Kenwood Corp. in the Central District of California on 8 March 2024, asserting US10021380B1 and US9948922B2. The case was voluntarily dismissed without prejudice on 7 October 2024 under Rule 41(a)(1)(A)(i), with each party bearing its own costs. No answer or dispositive motion was filed by the defendant.
VDPP asserted US10021380B1 (application US15/907614) and US9948922B2 (application US15/683623). Both patents relate to continuously adjustable 3D filter spectacles incorporating multi-layered variable tint materials capable of rapid optical state transitions — technology at the intersection of active eyewear and display filtering systems.
A without-prejudice dismissal means VDPP’s infringement claims were not adjudicated on the merits, and VDPP retains the legal right to refile the same claims against JVC Kenwood in the future. JVC Kenwood received no declaratory judgment of non-infringement or invalidity, meaning it holds no formal immunity from reassertion of either patent.
Federal Rule of Civil Procedure 41(a)(1)(A)(i) entitles a plaintiff to dismiss an action without a court order by filing a notice of dismissal at any time before the defendant serves an answer or a motion for summary judgment. Because JVC Kenwood had not filed either, VDPP had the unilateral right to dismiss, and the dismissal took effect automatically upon filing of the notice.
The public record does not confirm or deny a licensing or settlement agreement. The dismissal notice is silent on any commercial arrangement. A pre-answer Rule 41 voluntary dismissal is consistent with either a private licensing resolution or a unilateral strategic withdrawal by the plaintiff. Without court-filed settlement papers, the underlying commercial outcome remains undisclosed.
