Case Overview
In a decisive ruling that reinforces the strength of Signify’s expansive LED lighting patent portfolio, the U.S. District Court for the District of Nevada entered judgment of $410,544.00 in favor of Signify North America Corporation against Lepro Innovation, Inc. The case, filed December 19, 2022, and closed February 11, 2026 (Case No. 2:22-cv-02095), spanned approximately 1,150 days and involved seven U.S. patents covering foundational LED lighting technologies.
For patent attorneys, IP professionals, and R&D teams operating in the lighting, semiconductor, or consumer electronics sectors, this case offers critical signals: Signify continues aggressively enforcing its LED patent portfolio against competitors, and courts are receptive to multi-patent infringement claims when products implicate core lighting system innovations. The outcome underscores the financial and operational risks facing companies that commercialize LED products without rigorous freedom-to-operate analysis.
The Parties
⚖️ Plaintiff
World’s largest lighting company, formerly Philips Lighting. Dominant force in LED technology IP with thousands of patents.
🛡️ Defendant
Nevada-based LED lighting company marketing consumer and commercial LED products including recessed fixtures and modules.
The Patents at Issue
Seven U.S. patents were asserted, spanning a broad cross-section of LED system architecture. These patents cover foundational LED technologies registered with the U.S. Patent and Trademark Office (USPTO).
- • USRE049320E — Reissue patent on LED technology
- • US8063577B2 — LED operation methods and driver circuits
- • US9709253B2 — Lighting systems and illumination condition modulation
- • US7038399B2 — LED driver circuit and power delivery methods
- • US7352138B2 — Power supply apparatus for lighting devices
- • US7014336B1 — Lighting device with integrated RF antenna
- • US7348604B2 — Light-emitting module technology

The Verdict & Legal Analysis
Outcome
The Nevada District Court entered final judgment in favor of Signify North America Corporation, awarding $410,544.00 in damages against Lepro Innovation, Inc. The verdict cause is classified as an Infringement Action, confirming the court’s determination that Lepro’s LED products infringed one or more of Signify’s asserted patents.
The case, filed December 19, 2022, and closed February 11, 2026, spanned approximately 1,150 days. The extended timeline reflects the procedural complexity inherent in multi-patent LED litigation, including claim construction, validity challenges, and damages expert proceedings.
Key Legal Issues
With seven patents asserted across interconnected LED technology domains — driver circuits, power delivery, RF-integrated fixtures, thermal lighting modules, and illumination control systems — Signify mounted a portfolio-wide infringement case rather than relying on any single patent. This multi-patent strategy is a hallmark of dominant IP holders, increasing the probability of sustaining claims and maximizing damages. The $410,544 damages figure likely reflects a reasonable royalty calculation, consistent with courts’ application of the Georgia-Pacific factors.
This case reinforces that portfolio assertion strategies remain effective, even against experienced defense teams, and that reissue patents (like USRE049320E) continue to be viable enforcement vehicles.

Seven U.S. patents were asserted: USRE049320E, US8063577B2, US9709253B2, US7038399B2, US7352138B2, US7014336B1, and US7348604B2, covering LED driver circuits, RF-integrated lighting, power delivery methods, and illumination control systems.
The Nevada District Court entered judgment in favor of Signify North America Corporation in the amount of $410,544.00 against Lepro Innovation, Inc.
It reinforces Signify’s willingness to litigate multi-patent infringement actions to final judgment against commercial LED product companies, signaling heightened enforcement risk for manufacturers and sellers of LED fixtures and modules without comprehensive FTO clearance.
