Microsoft accused of patent infringement in Lumia 950 smartphones

Lumia 950Patent licensing firm, Lemaire Illumination Technologies had filed a complaint at the US District Court for the Eastern City of Texas, Marshall Division against Microsoft.

According to the complainant, Microsoft had infringed patents covering pulsed light-emitting diode (LED) illumination and apparatuses and methods.

The patents mentioned in the complaint are US numbers 6,095,661, called “Method and apparatus for an LED flashlight”; 6,488,390, titled “Color-adjusted camera light and method”; and 9,119,266, called “Pulsed LED illumination apparatus and method”.

The claim said, “When the camera of the Lumia 950 smartphone device is activated to capture an image, the electrical control circuit selectively provides a set of pulses from the battery to the triple LED flash, which generates a light output of the one or more LEDs.”

Lemaire further alleged that the pulses change to control a “color spectrum of the light output of the one or more LEDs of the triple LED flash and adjusts an LED on-time, thereby controlling the light output as the DC voltage source charge varies”.

“Microsoft had infringed in a ‘willful, wanton, malicious, bad-faith, deliberate, consciously wrongful or flagrant manner’, which is a shocking case of culpable behavior,” the claim added.

Lemaire is seeking a jury trial, general and special damages, triple damages and injunctive relief.

Microsoft launched the Lumia 950 smartphones in October 2015.
