Microsoft has previously claimed that Android infringes some of its patents, and offered a licensing program to vendors of handsets running the operating system.
So far Samsung, HTC, ZTE, LG Electronics and Hon Hai have all paid up to make Microsoft laywers go away.
In its complaint, Microsoft alleged that some of the features of the Kyocera smartphones infringe patents the software company holds in the areas of power management for enhanced battery life, “self-aware” devices that respond to changes in the user’s surroundings, text messaging and doing multiple tasks on a computing device at the same time.
The Kyocera phones are offered in the US through operators like Verizon and AT&T and retail chains like Walmart and Best Buy.
