Feit Electric Announces First Patent Enforcement Action Against Infringing White LED Filaments


Feit Electric Company, Inc. (“Feit Electric”), a leading global lighting and smart home brand headquartered in California, today announced that on February 2, 2024, it commenced a patent infringement action against Ledvance, LLC (“Ledvance”) in the United States District Court for the Eastern District of Kentucky. Despite being warned by Feit Electric, Ledvance imported and then sold white LED filament light bulbs marketed under the brand name Sylvania.

Feit Electric introduced light bulbs with white LED filaments in August 2022 and the fresh alternative to the traditional yellow filament quickly appealed to retailers and consumers. Anticipating that other light bulb suppliers might copy the Feit Electric white LED filament bulbs, Feit Electric announced to the industry that it owns a set of patents directed to covering the yellow material used on LED filaments.

“Not only did we widely announce to the industry that Feit Electric owns a set of patents directed to covering the yellow material used on LED filaments, but we also specifically and directly informed Ledvance as well as retailers and other manufacturers” said Alan Feit, President of Feit Electric. “Despite those warnings, Ledvance went forward with infringing products.”

Feit Electric is seeking an injunction to bar the further importation and sale of infringing white LED filament light bulbs, for damages, and for enhanced damages and attorney fees for willful infringement.

“While we would prefer that our competitors respect our patents, we are committed to enforcing our patents against infringers if they do not.  We also hope that retailers look to us for light bulbs with visible white filaments, rather than infringers,” said Mr. Feit.

Feit Electric’s new line of white filament decorative lighting is available at The Home Depot and Ace Hardware stores.  For more information on Feit Electric’s white filament product line visit feit.com.
Last year we introduced the first ever white filament bulb on the market in response to user and retailer concerns about the distracting yellow filament found in traditional bulbs. Unfortunately, with every innovation come imitations. Today, we're announcing the issuance of patents safeguarding against white filament infringement. Our commitment includes enforcing these patents against those who attempt to replicate our white filament products.

LOS ANGELES, Calif. – Sept 19, 2023 – Feit Electric Company, Inc. (“Feit Electric”), a leading global lighting and smart home brand headquartered in California, today announced that its innovative light bulbs with visible white filaments are protected by a set of patents, the “white filament patents.”

“We spend a lot of time reading customer reviews and listening to retailer feedback,” said Alan Feit, President of Feit Electric. “And we started hearing that some consumers had concerns about the more distinctive yellow filaments in LED bulbs especially when the lights were off in a fixture without any shades. They loved everything else about the light quality, long life, and energy savings of LED but not everyone liked the look. So, we wanted to introduce a fresh alternative to the traditional yellow filament with a more modern and minimal style.”

Unfortunately, Feit Electric’s innovation is prompting others to copy and to offer likely infringing products to retailers, even after the suppliers and the retailers have been put on notice. The white filament patents are directed to a covering for the yellow material used on LED packages, including but not limited to LED filament packages and SMD LED packages: U.S. Patent Nos. 8,604,678; 8,610,340, 8,610,341, 8,614,539, and 8,957,585.

Mr. Feit noted that “We believe that our patents are fundamental and dominant for covering the yellow material used for LED filaments.” Mr. Feit also said that there are several misunderstandings in the market to clear up.
  • Feit Electric has not licensed its white filament patents to any other light bulb supplier.
  • Owning or having a license in any other patent that is supposedly directed to white filaments does not preclude infringement of the Feit Electric white filament patents – a patent is a right to exclude, not a right to practice.
  • Another light bulb supplier supposedly has a patent covering white filaments. That patent is based on a patent application filed long after the Feit Electric white filament patents were filed, and such patent is therefore likely invalid in view of the Feit Electric white filament patents. And more importantly, we believe that it is not possible to practice that patent without infringing the Feit Electric white filament patents.
  • It is our understanding that some LED package suppliers and/or some bulb suppliers have been offering a form of patent infringement insurance for a royalty. Patent infringement insurance is only as good as the entity offering such protection and it does not preclude a retailer from being sued and liable for patent infringement.

“While we would prefer that our competitors respect our patents, we are committed to enforcing our patents against infringers if they do not. We also hope that retailers look to us for light bulbs with visible white filaments, rather than infringers,” said Mr. Feit. Feit Electric’s new line of white filament decorative lighting is available at The Home Depot and Ace Hardware stores.
