Inventor-controlled NPE Lemaire Illumination Technologies LLC has added Microsoft (2:17-cv-00729) to its sole litigation campaign, just over two weeks after the dismissal of its two lawsuits against LG Electronics (LGE). As in those previous cases, Microsoft is alleged to infringe three patents generally related to controlling and powering a solid-state light source such as a light-emitting diode (LED), with the color-adjusted camera flash systems of its Lumia 950 smartphone lineup at issue (including those from the single- and dual-SIM variants of the smaller Lumia 950 as well as the Lumia 950 XL).
LED Tech Developmentfiled suit against Samsung, alleging that Samsung’s tablet and notebook computers infringe four patents related to constant light output pulsed LED illumination, color-adjusted camera light, and an LED flashlight. LED Tech Development has filed four prior suits since July 2012 against Apple, Coleman Company, Home Depot, and Mag Instrument. The patents-in-suit originated with Lemaire Illumination Technologies and were assigned to LED Tech Development in March 2012. RPX reviewed the patents-in-suit as part of an open market opportunity (Lemaire) in January 2012. 10/15, District of Delaware, no judge yet assigned, 1:2012cv01325.
