The first lawsuit filed by Mira Advanced Technology Systems, Inc. (MATS), against Microsoft in 2016, met its demise before the Patent Trial and Appeal Board (PTAB). The Board invalidated both patents-in-suit—generally related to storing, for later presentation, a “conversation point for a future phone call” in association with an entry in a list of contacts—in light of certain prior art, in decisions summarily affirmed by the Federal Circuit. The plaintiff has now returned to litigation, this time accusing Alphabet (Google) (1:21-cv-00371) of infringing a patent issuing in March 2020 in the same family, this one generally related to providing location-based notifications based on a device’s GPS coordinates.
