CHM Industries has filed a patent infringement lawsuit against Current Lighting Solutions, LLC, escalating a long-running dispute over high mast luminaire technology.

The CHM Industries patent infringement lawsuit was filed 19 December, 2025, in the U.S. District Court for the District of Delaware. The complaint alleges infringement of four CHM-owned patents related to high mast LED luminaires and associated thermal and structural designs.

According to the filing, CHM Industries claims that Current Lighting Solutions—formerly known as GE Lighting Solutions—has infringed multiple patents covering core elements of CHM’s Condor CLED high mast luminaire family.

Background of the Dispute

CHM Industries, based in Saginaw, Texas, has manufactured high mast lighting systems, LED luminaires, and control solutions since 1996. Over time, the company secured patent protection for several generations of its high mast luminaire designs.

The CHM Industries patent infringement lawsuit centers on four asserted patents: U.S. Patent Nos. 9,677,754; 9,903,581; 10,571,112; and 11,473,767. These patents cover structural separation of power and LED housings, thermal management features, and rotational components in high mast luminaires 

Current Lighting Solutions, headquartered in Ohio and incorporated in Delaware, competes directly in the high mast lighting market. Its accused product is the Evolve LED Roadway Light High Mast Luminaire (ERHM), which CHM alleges has been sold since at least 2017.

NDA, Licensing, and Royalty Dispute

Notably, the complaint outlines a prior business relationship between the companies. In 2014, CHM and GE Lighting Solutions entered into a non-disclosure agreement related to a North Carolina Department of Transportation opportunity.

CHM alleges it provided a Condor CLED sample unit for evaluation under that NDA. Although GE did not pursue the project with CHM’s product, the lawsuit claims the technology was later incorporated into GE’s ERHM luminaire.

After CHM notified GE of alleged infringement in 2017, the parties entered into a settlement and license agreement effective November 1, 2018. That agreement required royalty payments for licensed products.

However, the CHM Industries patent infringement lawsuit alleges that Current stopped paying royalties on certain ERHM configurations, claiming they were outside the license scope. CHM disputes that interpretation and asserts that unpaid sales constitute unauthorized use of its patented technology.

Allegations of Willful Infringement

The complaint asserts direct, contributory, and induced infringement for each of the four patents. Additionally, CHM alleges willful infringement, citing prior notice of the patents and the executed license agreement.

As a result, CHM seeks monetary damages, treble damages for willful infringement, attorneys’ fees, and injunctive relief. The requested injunction would prohibit Current from manufacturing, selling, or importing the accused products in the United States.

CHM has also demanded a jury trial on all triable issues.

Industry Implications

While the case remains in its early stages, the CHM Industries patent infringement lawsuit highlights ongoing tensions around intellectual property in the high mast lighting segment.

As LED platforms evolve, disputes over thermal design, modular housings, and system architecture continue to surface across the industry. Consequently, this case may attract close attention from manufacturers, specifiers, and municipal buyers alike.

At publication time, Current Lighting Solutions has not publicly responded to the complaint.

EdisonReport will continue to monitor developments as the litigation proceeds.
