VDPP, LLC v. Garmin, Ltd. — Dismissed Without Prejudice After 83 Days
VDPP, LLC filed an infringement action against Garmin, Ltd. in Florida’s Southern District asserting two patents covering variable-tint 3D spectacles technology. The court dismissed the case sua sponte after 83 days, finding the complaint was a defective shotgun pleading — before Garmin was even served.
Sua Sponte Shotgun Pleading Dismissal Before Garmin Was Served
On June 3, 2025, VDPP, LLC filed an infringement action against Garmin, Ltd. in the U.S. District Court for the Southern District of Florida (Case No. 1:25-cv-22536), presided over by Judge Darrin P. Gayles. The complaint asserted two patents — US9426452B2 and US10021380B1 — both directed to faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials.
On August 25, 2025 — just 83 days after filing — Judge Gayles issued a paperless order dismissing the case without prejudice following a sua sponte review of the record. The court identified the complaint as a classic ‘shotgun pleading’: Count II impermissibly incorporated all preceding paragraphs and counts, a defect the Eleventh Circuit has condemned for decades. Critically, Garmin had not yet been served with the complaint at the time of dismissal.
The court did not close the matter entirely: VDPP was ordered to file an amended complaint and effect service upon Garmin by September 12, 2025, with the case administratively closed pending that action. This means the dismissal is procedural rather than substantive — VDPP retains the ability to refile, but must cure the pleading deficiency. No merits ruling was reached, and Garmin’s exposure to the asserted patents remains legally unresolved from the public record.

Dismissed without prejudice: what the shotgun pleading ruling means for both parties
Shotgun pleading: why courts dismiss before reaching the merits
A ‘shotgun pleading’ incorporates all prior allegations into each successive count, making it impossible to determine which facts support which claim. The Eleventh Circuit has condemned this practice for over 30 years. Judge Gayles acted sua sponte — without any motion from Garmin — to dismiss the complaint on this basis alone. No substantive analysis of the asserted patents was required or performed.
Procedural defect — no merits rulingVDPP must refile a clean complaint by September 12, 2025
Dismissal without prejudice preserves VDPP’s right to refile. The court explicitly ordered VDPP to submit an amended complaint and effect service on Garmin within the deadline. If VDPP complies, the litigation continues on a corrected procedural footing. If it fails to meet the deadline, the administrative closure could convert into a full dismissal. The merits of the patent infringement claims against Garmin remain entirely unlitigated.
Refile deadline: Sept 12, 2025Garmin was never served — but the patent threat has not gone away
Garmin, Ltd. had not been served with process at the time of dismissal, meaning it incurred no formal litigation burden in this proceeding. However, the underlying patents — US9426452B2 and US10021380B1 — remain asserted, and VDPP has a clear path to refile. Garmin should anticipate a corrected complaint and may need to prepare a substantive response to the variable-tint spectacles infringement allegations.
Patent threat persists post-dismissalVariable-tint spectacles patents remain live — sector should monitor refile
Because the dismissal was without prejudice on procedural grounds, neither patent has been invalidated, construed, or held unenforceable. Any company operating in the adjustable-lens, smart eyewear, or heads-up display technology space faces the same latent exposure to US9426452B2 and US10021380B1 as before this action. The refile deadline and any subsequent service on Garmin will be the next material signpost for the sector.

Official order — verbatim text
The order is notable for what it does not decide: Judge Gayles made no finding on infringement, claim construction, or patent validity. The dismissal rests entirely on the Eleventh Circuit’s long-standing prohibition on shotgun pleadings — a structural defect in the complaint itself. By ordering VDPP to file an amended complaint and serve Garmin by September 12, 2025, the court signals that the litigation may continue if the pleading deficiency is cured, meaning the substantive dispute over US9426452B2 and US10021380B1 remains open.
US9426452B2 & US10021380B1 — Variable-Tint 3D Spectacles Technology
US9426452B2 (application no. US14/850750) and US10021380B1 (application no. US15/907614) both sit within the technical domain of adaptive optical filtering for stereoscopic display systems. The patents cover faster state transitioning mechanisms for continuous adjustable 3Deeps filter spectacles employing multi-layered variable tint materials — a technology designed to improve the speed and precision with which lens tint states are modulated in real-time display environments.
The strategic significance of these patents extends beyond traditional 3D cinema eyewear. As wearable display technology, augmented reality, and heads-up display systems increasingly rely on adaptive lens technologies, patents covering variable-tint state control become relevant to a broad competitive set. Garmin’s portfolio of wearable and navigation devices with display integration puts it within a plausible infringement read — though no claim construction or infringement finding has been made in this case. Companies developing smart eyewear or adaptive optics should monitor this patent family closely.
Should your team run an FTO against US9426452B2 and US10021380B1?
Any R&D team developing adjustable-lens eyewear, adaptive optical filters, stereoscopic display accessories, or wearable display systems with variable-tint functionality should assess exposure to these two patents. The fact that VDPP has already targeted a company of Garmin’s scale suggests active enforcement intent. The without-prejudice dismissal means both patents are fully enforceable and the assertion campaign is likely to resume with a corrected complaint.

What this case signals for the smart eyewear and wearable optics IP landscape
A pre-service procedural dismissal leaves both asserted patents fully active and the underlying dispute unresolved — a signal for the sector.
Shotgun pleading dismissals create a false sense of safety for defendants
A without-prejudice dismissal on pleading grounds does not extinguish the underlying patent claims. Garmin — and any similarly positioned defendant — should treat this as a temporary reprieve rather than a win. VDPP retains full standing to refile a corrected complaint and pursue infringement claims on the merits.
Sua sponte review in the Southern District of Florida is an active risk
Judge Gayles acted without any motion from Garmin, demonstrating that the Southern District of Florida actively screens complaints for procedural defects. Patent plaintiffs filing in this district should ensure complaints use clean, count-specific pleading structures to avoid early dismissal before service is even attempted.
VDPP v Garmin — key questions answered
Judge Darrin P. Gayles dismissed the case sua sponte on August 25, 2025, finding the complaint was a shotgun pleading — specifically, Count II impermissibly incorporated all preceding paragraphs and counts. The Eleventh Circuit prohibits this pleading structure. The dismissal was without prejudice, and VDPP was ordered to file an amended complaint and serve Garmin by September 12, 2025.
VDPP asserted US9426452B2 (application US14/850750) and US10021380B1 (application US15/907614). Both patents cover continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials, specifically faster state transitioning mechanisms for adaptive lens systems. No claim construction or infringement ruling was reached in this proceeding.
A dismissal without prejudice does not resolve the merits. VDPP retains the right to refile a corrected complaint asserting the same patents against Garmin. The court set a September 12, 2025 deadline for VDPP to file an amended complaint and effect service. If VDPP meets that deadline, litigation continues. If not, the administrative closure may become permanent.
No. The court’s dismissal order explicitly notes that Garmin had not been served with process as of August 25, 2025 — nearly three months after the complaint was filed on June 3, 2025. This means Garmin incurred no formal litigation burden in this proceeding, though the underlying patent claims remain active and Garmin should anticipate a refiled action.
A shotgun pleading is one that incorporates all prior allegations into each successive count, making it impossible to identify which facts support which legal claim. The Eleventh Circuit has condemned this practice for over 30 years as it forces defendants and courts to parse out which allegations are relevant to each cause of action. Judge Gayles cited Keith v. DeKalb Cnty., Georgia, 749 F.3d 1034 (11th Cir. 2014) as controlling authority.
