Word to Info Targets Microsoft’s Cortana

April 21, 2017

Word to Info, Inc. has filed suit against Microsoft (2:17-cv-00596) in the Western District of Washington, asserting the same seven patents (5,715,468; 6,138,087; 6,609,091; 7,349,840; 7,873,509; 8,326,603; 8,688,436) that have been at issue in the natural language processing campaign that the NPE began back in December 2014. At issue is Microsoft’s Cortana virtual assistant; the new case follows the filing of a motion for partial dismissal by Nuance Communications in the District of Massachusetts that essentially repeats arguments, already rejected by the Northern District of California, concerning whether the later-issuing patents in Word to Info’s family are invalid for failure to properly perfect their chains of priority to the earlier patents.
