Ramey LLP has filed a new patent infringement lawsuit on behalf of its client, VDPP, LLC, against Garmin USA, Inc. The lawsuit, filed on June 3, 2025, in the Southern District of Florida, Miami Division, centers on U.S. Patent No. 9,426,452, titled “Faster State Transitioning for Continuous Adjustable 3Deeps Filter Spectacles Using Multi-Layered Variable Tint Materials.”

The patented technology involves innovative advancements in adaptive eyewear, specifically systems that allow faster and smoother transitions in tint for variable light conditions using layered filter materials. These developments play an increasingly important role in industries such as wearable tech, augmented reality, and optical display systems.
