VDPP, LLC vs. Rivian Automotive: 3D Eyewear Patent Case Ends in Voluntary Dismissal

Introduction

In a case that quietly closed before Rivian Automotive, Inc. ever filed an answer, VDPP, LLC voluntarily dismissed its patent infringement claims without prejudice on February 18, 2026 — ending a 169-day dispute that raised pointed questions about 3D stereoscopic eyewear technology and automotive display innovation. Filed in the Western District of Texas on September 3, 2025, the action centered on two patents covering adjustable 3D filter spectacles and variable tint materials. The plaintiff’s pre-answer exit under Federal Rule of Civil Procedure 41(a)(1)(A)(i) is a procedural outcome worth examining closely.

For patent attorneys tracking non-practicing entity (NPE) assertion strategies, IP professionals monitoring automotive technology patent litigation, and R&D teams developing display or vision-enhancement systems, this case offers meaningful signals — even without a merits ruling. The absence of an adjudicated outcome does not diminish the strategic intelligence embedded in how and why this case ended.

Case Overview

The Parties

The Patents at Issue

Two utility patents formed the basis of this infringement action, covering electronically adjustable stereoscopic eyewear:

• • US9699444B2 — “Continuous adjustable 3Deeps Filter Spectacles for optimized 3Deeps stereoscopic viewing, control method and means therefor, and system and method of generating and displaying a modified video”
• • US9716874B2 — “Faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials”

The Accused Product(s)

The complaint targeted Rivian’s technology stack in ways that implicated its in-vehicle visual display systems, though specific accused products were not enumerated in the available case data. The connection between adjustable 3D filter spectacle technology and an EV manufacturer potentially touches on head-up display (HUD) systems, passenger entertainment platforms, or augmented vision interfaces under development.

Legal Representation

Plaintiff’s Counsel: William P. Ramey III of Ramey LLP (Houston, Texas) represented VDPP, LLC. No defense counsel of record appeared, consistent with the pre-answer procedural posture.

Litigation Timeline & Procedural History

The case was filed in the U.S. District Court for the Western District of Texas, a historically plaintiff-favorable venue for patent litigation and a preferred forum for NPE filings. Notably, Rivian never served an answer or motion for summary judgment during the case’s lifespan — a critical procedural fact that enabled the plaintiff’s unilateral exit under Rule 41(a)(1)(A)(i).

The 169-day duration from filing to closure reflects a case that never advanced beyond its earliest procedural stage. No claim construction proceedings, Markman hearings, or substantive motion practice appear in the available record.

The Verdict & Legal Analysis

Outcome

VDPP, LLC filed a Notice of Voluntary Dismissal Without Prejudice on February 18, 2026, citing Federal Rule of Civil Procedure 41(a)(1)(A)(i). The Western District Court confirmed the dismissal was self-effectuating the following day, ordering the clerk to close the case. Each party was ordered to bear its own costs, expenses, and attorney fees. No damages were awarded. No injunctive relief was issued.

Procedural Analysis: Rule 41(a)(1)(A)(i) Mechanics

The court’s closing order specifically references In re Amerijet Int’l, Inc., 785 F.3d 967, 973 (5th Cir. 2015), which confirms that a Rule 41(a)(1)(A)(i) notice is “self-effectuating and terminates the case in and of itself.” Because Rivian had not yet served an answer or summary judgment motion, VDPP retained the absolute right to dismiss without court approval. This is a bright-line procedural rule with significant strategic implications.

Critically, the dismissal was entered without prejudice. This means VDPP, LLC retains the right to refile these claims — against Rivian or any other defendant — subject to applicable statutes of limitations and any potential preclusion arguments.

Strategic Turning Points

Several factors likely contributed to the pre-answer dismissal:

• • Claim mapping challenges: Connecting adjustable stereoscopic eyewear patents to an EV manufacturer’s product line requires a non-obvious claim construction bridge.
• • Defendant’s litigation posture: Rivian, as a well-capitalized public company, likely signaled a vigorous defense.
• • Licensing resolution: Pre-answer dismissals in NPE cases frequently — though not always — reflect out-of-court licensing discussions.

Legal Significance

This case does not generate binding precedent on the merits of stereoscopic eyewear patent claims. However, it does reinforce the procedural value of Rule 41(a)(1)(A)(i) as a low-cost exit mechanism for patent plaintiffs who need to reassess strategy before locking into full-scale litigation. The Fifth Circuit’s Amerijet standard governs dismissal mechanics in this jurisdiction, and this case represents a clean application of that principle.

Strategic Takeaways

For Patent Holders: Early case assessment is essential before filing, particularly when asserting display or optics patents against defendants in adjacent technology sectors. The “without prejudice” exit preserves future assertion rights but does not pause statute of limitations analysis.

For Accused Infringers: A pre-answer posture in NPE cases can itself be a strategic asset — delay in answering is not inherently passive and may contribute to plaintiff recalibration. However, defendants should simultaneously prepare substantive defenses, including invalidity contentions and claim construction positions.

For R&D Teams: Patents covering adjustable optical systems and variable tint materials may carry broader application than their consumer-facing descriptions suggest. Freedom-to-operate (FTO) analyses in display, HUD, and vision-enhancement development should account for optics-adjacent patent portfolios.

Frequently Asked Questions

What patents were involved in VDPP, LLC v. Rivian Automotive?

The case involved US9699444B2 and US9716874B2, both covering continuously adjustable 3D filter spectacles and variable tint materials for stereoscopic viewing optimization.

Why was the case dismissed without prejudice?

VDPP, LLC filed a voluntary notice of dismissal under FRCP 41(a)(1)(A)(i) before Rivian served an answer or summary judgment motion, making the dismissal self-effectuating. No court approval was required.

Can VDPP refile against Rivian or others?

Yes. A dismissal without prejudice does not bar refiling, subject to applicable statutes of limitations and any court-imposed restrictions in future proceedings.
