Signify Returns to Court with New Patent Lawsuit Against Artika, Ending a Long Quiet Period
MARSHALL, Texas — After an extended period focused primarily on licensing negotiations rather than litigation, Signify has filed a new patent infringement lawsuit, this time targeting Canadian lighting manufacturer Artika For Living Inc, a lighting company based in Quebec, in the U.S. District Court for the Eastern District of Texas.
The lawsuit marks a notable development in Signify’s intellectual property enforcement strategy and comes just weeks after EdisonReport examined the company’s EnabLED licensing program and questioned whether manufacturers should revisit their licensing agreements.
In that article, we noted that it had been years since Signify filed a patent lawsuit against a new industry player, leading some in the industry to wonder whether the company had shifted toward negotiated licensing rather than courtroom enforcement. This new complaint suggests that while licensing remains Signify’s preferred approach, litigation remains very much part of its enforcement strategy when negotiations fail.
According to the Complaint, Licensing Came First
Rather than portraying this as a surprise lawsuit, the complaint outlines what Signify describes as a five-year effort to resolve the dispute without litigation.
According to the filing, Signify first contacted Artika in January 2021, notifying the company that certain LED products allegedly infringed Signify patents. The complaint alleges numerous follow-up communications over the next several years, including presentations explaining the EnabLED licensing program, multiple written notices identifying additional patents and products, conference calls, in-person meetings in Montreal, and repeated license offers.
The lawsuit alleges that despite these repeated communications, Artika declined to obtain a license.
Six Patents Asserted
The complaint asserts infringement of six U.S. patents covering a range of LED technologies, including:
- Configurable lighting systems featuring selectable color temperatures (CCT)
- LED driver technology
- LED power control methods
- Modular LED light engine technology
Signify states that it maintains a portfolio of more than 4,000 patents protecting its LED innovations.
Products Identified
The complaint specifically identifies several Artika products that allegedly infringe various patents, including:
- Maelstrom Pendant
- Coda Pendant
- Alton Flush Mount
- Essence Flare
- Essence Bar Pendant
- Altitude Flush Mount
The filing includes detailed claim charts attempting to map features of each product to the asserted patent claims.
Broad Distribution Cited
To establish jurisdiction and demonstrate U.S. sales activity, Signify alleges that Artika distributes products through multiple national retail channels, including Home Depot, Lowe’s and Costco, while also selling directly through its own website and authorized representatives. The complaint also references Bell & McCoy as one of Artika’s authorized sales representatives in Texas.
A Signal to the Industry
The timing of this lawsuit is significant.
As discussed in EdisonReport’s July analysis of the EnabLED licensing program, some manufacturers have recently been evaluating whether to renew, renegotiate, or reconsider their licensing agreements with Signify. Until now, one argument raised was that Signify had not recently pursued new infringement actions against companies operating outside its licensing program.
This filing changes that conversation.
Whether Artika ultimately prevails or the case settles before trial, the lawsuit demonstrates that Signify remains willing to enforce its patent portfolio through litigation after lengthy licensing discussions fail.
For companies currently evaluating their own relationship with Signify’s EnabLED program, the message from this filing appears clear: licensing discussions may last for years, but litigation remains a real possibility if the parties cannot reach an agreement.
As always, the complaint contains allegations only. Artika has not yet filed a response, and the Court has not made any findings regarding the merits of Signify’s claims.
