Google has filed a complaint against InfoGation Corporation (3:16-cv-05821), seeking a declaratory judgment that Google and its Android OEM partners do not infringe a single patent (6,292,743) generally related to producing navigation guidance from turn-by-turn directions generated from natural language output. The lawsuit comes in response to three cases brought by the NPE against HTC (3:16-cv-01902), Huawei (3:16-cv-01903), and ZTE (3:16-cv-01901) in July, which alleged that the companies’ Android smartphones infringe the ‘743 patent through their inclusion of Google Maps. Those proceedings remain in initial pleadings.
