Signify v. Lepro Patent Trial Set for 12 January 2026

For more than twenty years, Signify has pursued patent enforcement across the lighting industry. Most disputes ended quietly—through settlement, licensing, or dismissal. That pattern may change in early 2026. A jury trial is now set, in a case that until recently has flown under the radar.

On 12 January 2026, the U.S. District Court for the District of Nevada will hear Signify North America Corporation and Signify Holding B.V. against five related companies doing business under the “Lepro,” “Lighting Ever,” and “LE” brands. The trial should last about a week. It may become the closest Signify has come to a full trial and judgment in over two decades of patent enforcement.

The Patents in Question

Signify alleges that the defendants—Lepro Innovation Inc., LE Innovation Inc., Innovation Rules Inc., Home Ever Inc., and Letianlighting Inc.—infringed six LED-related patents. These are U.S. Patent Nos. 7,014,336; 7,038,399; 7,348,604; 7,352,138; 8,063,577; and RE49,320.

The patents cover driver circuits, power delivery methods, and light-emitting modules. They also include a design that integrates RF antennas into lighting devices. Signify argues that these innovations helped shape modern LED lighting. The company says protecting this intellectual property is essential for its brands, including Philips, Hue, Wiz, and Color Kinetics.

Partial Wins for Signify

The court has already granted summary judgment in Signify’s favor on several fronts. Defendants were found liable for infringing three patents: the ’399, ’138, and ’577. The court also rejected invalidity defenses against the ’336 and ’320 patents.

The upcoming trial will decide whether the defendants also infringed the ’336, ’604, and ’320 patents. It will also test whether the infringement was willful and how damages should be calculated. Signify seeks a permanent injunction, treble damages, and recovery of legal fees.

Defendants Push Back

The defendants deny infringement of the ’336, ’604, and ’320 patents. They argue that several claims in the other patents are invalid. They also say Signify’s damages model is inflated, the alleged infringement was not willful, and an injunction is not justified.

The companies share addresses, family ownership, and overlapping operations. They sell products through their websites and Amazon storefronts. Their collective defense is simple: Signify’s claims overreach, and its patents should not prevent competition in the LED market.

Why This Trial Matters

This trial is significant. Patent disputes in the lighting industry rarely reach a jury verdict. If Signify prevails, and the court awards enhanced damages or an injunction, the decision could reshape intellectual property enforcement in the LED sector.

Judge Jennifer A. Dorsey has scheduled jury selection and trial for 12 January 2026, with a calendar call set for 22 December 2025. Settlement remains possible, but the case is now firmly on track for trial.
