Signify Expands Patent Fight Over Tunable Fixtures
The latest lawsuit vs. Artika signals continued enforcement against CCT-selectable products
Signify has sued another lighting brand for allegedly using its color-tunable technology, and if the pattern holds, it will not be the last.
On July 31, Signify filed suit against Artika in the Eastern District of Texas, accusing the Quebec-based decorative and architectural lighting company of infringing six patents covering CCT-selectable fixtures, LED driver circuitry, and modular light engine construction.
The accused products, including the Maelstrom pendant, the Coda pendant, and the Alton flush mount, are not exotic specialty luminaires. They are the kind of tunable-white pendants and flush mounts sold at Home Depot, Lowes, and Costco, at price points built for volume rather than margin.
That distinction matters for lighting people watching this case. The patents Signify is asserting do not touch smart controls or networked systems. They cover the basic mechanics of switching between two or three color temperatures, a feature that has gone from premium option to retail default across the decorative segment in roughly five years.

The Pattern Behind the Filing
Two of the six patents asserted against Artika have a documented litigation history that predates this complaint by years.
The 11,408,588 patent, covering configurable lighting systems, was also asserted against ETI, against Liton Lighting, and against Lepro in cases filed or tried between 2025 and early 2026. The 7,737,643 patent, covering LED power control methods, has shown up in suits against EGLO, against Menards, and in a declaratory judgment action brought by Current against Signify itself.
Some of those cases settled quickly. One produced inequitable-conduct counterclaims that a federal judge dismissed while allowing a willfulness claim to proceed.
None of that immediately impacts Artika's case, and the merits of infringement remain for a jury to decide. But the recurrence of the same few patents across a half dozen defendants in eighteen months suggests these are not isolated skirmishes. They point to a portfolio Signify is actively working, patent by patent, against a segment of the market it considers underlicensed.
Notice, Venue, and the Long Runway
What separates Signify patent complaints from routine infringement filings is the paper trail the world’s largest lighting company builds first.
The complaint documents notice letters, licensing presentations, and an in-person meeting in Montreal stretching from January 2021 through July 2026, nearly five and a half years of correspondence built around Signify's EnabLED licensing program before a single count was filed. Roughly twenty paragraphs are devoted to establishing that Artika knew, and kept selling anyway, a foundation for the willfulness and enhanced-damages claims Signify is pursuing.
Venue tells its own story. Artika has no official U.S. offices, so Signify leaned on Bell & McCoy, an authorized Texas sales agent with an East Texas territory, to anchor jurisdiction in the Eastern District's Marshall Division, a court with a plaintiff-friendly reputation among patent litigators that needs no introduction.
What Comes Next
We reached out to both Signify and Artika for comment on the litigation. Artika declined to comment.
A Signify spokesperson provided the following statement: "We can confirm that on July 31, 2026, Signify filed a lawsuit against Artika For Living Inc., alleging infringement of six U.S. patents. The six asserted patents are part of the Signify EnabLED licensing program, under which licenses are available to companies offering products that practice these patented technologies. Signify believes that its patents are infringed and valid, and respects other companies' or individuals' intellectual property in the same way as it expects others to respect Signify's intellectual property."
For lighting people selling CCT-selectable fixtures through big-box channels or electrical distribution, the open question is not whether Artika infringed. It is how many more names sit on Signify's noncompliance list.
