Not the Brightest Idea: Microsoft’s Patent Infringement Legal Troubles


Lemaire Illumination Technologies LLC, an inventor-owned patent licensing entity sued Microsoft on Tuesday, saying the Redmond, Washington-based company’s headlining smartphone infringes on their patents. Lemaire’s complaint was filed in the U.S. District Court in Marshall, Texas, and claims that Microsoft’s Lumia 950 XL and Lumia 950 smartphones infringes on three of their patents relating to light-emitting diodes (LEDs) technology used to illuminate mobile device screens.

Lemaire Technologies is registered in Texas and is managed by Charles Lemaire, a patent lawyer and inventor located in Minnesota. According to the complaint, Lemaire holds a portfolio of more than half a dozen patents which describes various methods of improving the efficiency of LED lighting by means of controlling electric pulses. Lemaire brought a similar patent infringement case against LG Electronics Inc. in April. That case, which was filed in the Eastern District of Texas, alleged that LG’s G3 and G4 smartphones infringed on the same three patents claimed in the suit being brought now against Microsoft.

As Microsoft is arguably one of the largest patent holders in the mobile device arena, it is not such a novel idea that it would be subject to several lawsuits over the use of patents regarding the technology in its mobile devices. This past Thursday on November 9, Holotouch filed a separate lawsuit against Microsoft as well, alleging patent infringement on part of the tech giant. No further details about the case are known as of yet, but the case is Holotouch Inc. v. Microsoft Corp., 17cv08717, in the U.S. District Court for the Southern District of New York..

Lemaire Illumination Technologies is being represented by Katarzyna Brozynski of Strasburger & Price. The case is Lemaire Illumination Technologies LLC v. Microsoft Corp., 17cv00729, in the U.S. District Court for the Eastern District of Texas.
