The complaint

The case is Digital Lumens Holding Company, LLC v. HLI Solutions, Inc., No. 7:26-cv-00436 (W.D. Tex.), a 73-page complaint for patent infringement filed October 26, 2026, in the Midland-Odessa Division, ECF No. 1. The complaint says Digital Lumens is a Delaware limited liability company with a place of business in Los Angeles, California. It alleges, upon information and belief, that HLI Solutions is a Connecticut corporation and Current Lighting Solutions a Delaware limited liability company, both with a place of business in Round Rock, Texas, and that Bell & McCoy Companies is a Delaware limited liability company based in Houston, Texas. The complaint refers to HLI and Current Lighting Solutions together as Current Lighting.

Jurisdiction, venue and joinder

The complaint pleads subject matter jurisdiction under 28 U.S.C. 1331 and 1338 and venue under 28 U.S.C. 1400(b). It points to Current Lighting's training Institute in Round Rock, Texas, its authorized distributors in Midland, Odessa, Austin, El Paso, Waco and San Antonio, and its use, on information and belief, of Bell & McCoy Companies as its authorized agent in Texas. It alleges that Bell & McCoy operates retail stores in the district and, on information and belief, uses them to market and sell Current Lighting products. It pleads joinder under 35 U.S.C. 299(a), on information and belief, because the defendants commonly make, use, sell, offer to sell or import the same accused products.

The patents

The complaint says Digital Lumens, Inc., founded in 2008, developed the patent portfolio, and alleges that Digital Lumens Holding is the assignee and owner of each asserted patent. It groups the patents as occupancy and ambient light sensing, power metering, and rule-based control.

USPTO assignment records show each of the six patents assigned by its inventors to Digital Lumens, Inc., and all six then assigned by Digital Lumens to Osram Sylvania Inc. by an assignment executed August 17, 2021 and recorded August 19, 2021 (Reel/Frame 57229/0146). Osram Sylvania assigned all six to Digital Lumens Holding Company, LLC by an assignment executed November 20, 2025 and recorded April 24, 2026 (Reel/Frame 74468/0601), six months before the complaint.

U.S. Patent 10,306,733, Methods, systems, and apparatus for intelligent lighting, issued May 28, 2019. Asserted claim 1 covers a lighting fixture with a memory storing a transfer function that maps target light levels to operating states, an ambient light sensor, an occupancy sensor, and a processor that moves between operating states on an occupancy event and determines the new target light level from the measured ambient light and the stored transfer function, and a light source that changes its output accordingly.

U.S. Patent 10,485,068, Methods, apparatus, and systems for providing occupancy-based variable lighting, issued November 19, 2019. Asserted claim 1 covers a method of controlling a light fixture that detects presence and ambient light, enters an active state at a dimming level based on the ambient light, enters a countdown state at that level for a controllably variable transition delay time when the person or object leaves, and enters an inactive state if the delay expires without detecting presence.

U.S. Patent 11,339,927, Methods, apparatus and systems for providing occupancy-based variable lighting, issued May 24, 2022. Asserted claim 1 covers a lighting apparatus with dimmable LED-based light sources, an occupancy sensor, an ambient light sensor, and a controller that sets a controllably variable delay time in response to a signal from a remote device and controls the light sources through active and countdown states based on the occupancy and ambient light signals.

U.S. Patent 8,138,690, LED-based lighting methods, apparatus, and systems employing LED light bars, occupancy sensing, local state machine, and meter circuit, issued March 20, 2012. Asserted claim 1 covers a lighting fixture with a housing, an occupancy sensor, LED light bars, and a power management module with a memory storing active and inactive power output levels, a digital light agent controller implementing a state machine, and a meter circuit that determines the light bars' energy usage.

U.S. Patent 8,339,069, Power management unit with power metering, issued December 25, 2012. Asserted claim 1 covers a method of storing active and inactive power output level parameters, receiving occupancy data, controlling a fixture's light level based on the occupancy data and/or the parameters, measuring the fixture's energy usage, and logging a power measurement in memory.

U.S. Patent 8,841,859, LED lighting methods, apparatus, and systems including rules-based sensor data logging, issued September 23, 2014. Asserted claim 45 covers a lighting fixture with a sensor measuring an environmental parameter according to at least one rule, LED light bars, a power management module, a memory logging sensor data, and a frame housing with an integral sensor bay holding a sensor module whose lens sits along the fixture's bottom plane.

The accused products

The complaint accuses the Daintree Lighting Control Solutions, NX Lighting Controls and LightGRID+ product lines, including compatible software, controllers, commissioning platforms, sensors, luminaires, the LightGRID+ Gateway and Enterprise Server, fixture modules, photocells, motion sensors and wall switches. It uses Daintree as the example for the '733, '068 and '927 patents, LightGRID+ for the '690 and '069 patents, and NX Lighting Controls for the '859 patent.

The infringement allegations

The complaint pleads six counts, one per patent. Each alleges direct infringement under 35 U.S.C. 271(a) and, on information and belief, indirect infringement: inducement under 271(b) and contributory infringement under 271(c) and (f). Each alleges that the defendants have known of the patent since at least the filing of the complaint and that their infringement is willful.

The relief sought

The prayer asks for a judgment of infringement, past damages, costs, expenses and interest, an accounting and supplemental damages, a post-judgment running royalty, a finding of willfulness with treble damages under 35 U.S.C. 284, a declaration that the case is exceptional with attorneys' fees under 35 U.S.C. 285, an injunction, and other relief.
