Federal Circuit Upholds Validity Of Philips Patent On Dimmable LEDs

• The Patent Trial and Appeal Board recently decided that a Philips patent on dimmable LED technology is valid despite a challenge from a competitor. That decision was later affirmed by the U.S. Court of Appeals for the Federal Circuit.
• The patent at issue has been well-litigated, with Philips asserting the patent against numerous competitors in federal courts and at the U.S. International Trade Commission.

A patent directed to dimmable LED technology was upheld as valid in an appeal to the U.S. Court of Appeals for the Federal Circuit. The patent is owned by Philips Lighting North America Corporation, a subsidiary of Dutch consumer product giant Koninklijke Philips N.V. The Federal Circuit's decision marks the unsuccessful conclusion of a challenge to the patent's validity brought by a competitor of Philips Lighting called Wangs Alliance Corporation, which does business under the name WAC Lighting.
