The Verdict & Legal Analysis
Outcome
The case concluded via voluntary dismissal with prejudice filed by VDPP, LLC on April 19, 2024, and formally acknowledged by the Court on April 29, 2024. No damages were awarded, and no injunctive relief was granted or denied on the merits. Each party was ordered to bear its own costs, expenses, and attorney fees.
Key Legal Issues
The Western District of Texas’s analysis focused on the critical procedural posture under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The dismissal with prejudice permanently extinguishes VDPP’s ability to reassert these specific claims against Sharp Corporation on the same patents, making it a distinctive exit from litigation before substantive judicial engagement.

✅ Key Takeaways for 3D Display & Optics IP
Rule 41(a)(1)(A)(i) self-effectuating dismissals require no court approval before defendant’s answer — a critical procedural checkpoint.
Search related case law →With-prejudice dismissals permanently bar re-assertion against the same defendant; distinguish carefully from without-prejudice exits.
Explore precedents →No fee-shifting order under § 285 suggests early resolution or mutual agreement on costs.
Understand fee shifting →The Western District of Texas remains a high-activity venue for display technology patent litigation.
Analyze WDTX trends →Monitor U.S. Patent Nos. 9,699,444 B2 and 11,039,123 B2 for continued assertion activity against other defendants.

The case involved U.S. Patent No. 9,699,444 B2 and U.S. Patent No. 11,039,123 B2, both covering faster state transitioning for 3Deeps filter spectacles using multi-layered variable tint materials.
Plaintiff VDPP, LLC filed a voluntary notice of dismissal with prejudice under FRCP 41(a)(1)(A)(i) before Sharp served an answer or summary judgment motion, making the dismissal self-effectuating.
The early dismissal without merits ruling leaves both patents available for future assertion against other parties, while the with-prejudice outcome permanently bars claims against Sharp — a pattern common in NPE licensing-driven litigation.
