On November 2, 2012, Koninklijke Philips Electronics N.V. and Philips Solid-State Lighting Solutions, Inc. filed suit in the U.S. District Court for the District of Massachusetts, accusing Aurora Lighting Inc. of patent infringement of seven U.S. patents for light-emitting diode lighting technology.
The accused Aurora devices include various LED retrofit bulbs designed to be installed in conventional light sockets, as well as downlight flat panel products and wallwasher products. The asserted patents disclose various power supply configurations (see here, here, and here), multicolor bulbs (see here and here), and luminaire configurations (see here and here).
Some of the asserted patents were among the dozens of U.S. patents obtained by Philips through its acquisition of Color Kinetics, Inc. in 2007 for a purchase price of about $791 million. Color Kinetics was then renamed to become Philips Solid-State Lighting Solutions, Inc.
