Wilmington, MA, September 8, 2026: LEDVANCE, a global leader in general lighting solutions, announced today that a three-judge panel of the U.S. Patent Trial and Appeal Board (PTAB) has issued a Final Written Decision finding all challenged claims in Feit Electric’s white filament LED patent, U.S. Patent No. 8,604,678 (the “‘678 patent”), unpatentable.
In a 110-page opinion, the PTAB determined that every challenged claim was not patentable on multiple grounds and denied the patent owner’s contingent request to amend the claims. The PTAB also issued a separate 25-page opinion denying Feit Electric’s motion to terminate the proceedings.
In 2024, Feit Electric initiated proceedings against LEDVANCE in the U.S. District Court for the Eastern District of Kentucky, alleging infringement of the ‘678 patent. In response, LEDVANCE challenged the validity of the asserted claims by filing a petition for Inter Partes Review with the PTAB. The PTAB has now agreed with LEDVANCE on all challenged claims of the ‘678 patent.
“This decision validates LEDVANCE’s position regarding the challenged claims and reinforces our customers’ confidence in the innovation, quality, and reliability behind LEDVANCE and SYLVANIA branded general lighting products. We remain committed to delivering industry-leading lighting solutions and protecting the innovation that drives value for our customers,” said Andy Martin, General Counsel, LEDVANCE US.
