NPE Olivistar LLC has filed six suits, one each against makers of fitness monitoring devices, including Aliph (Jawbone) (2:14-cv-00534), Fitbit (2:14-cv-00539), Garmin (2:14-cv-00540), Nautilus (2:14-cv-00537), Nike (2:14-cv-00541), Oregon Scientific (2:14-cv-00542), and Polar Electro (2:14-cv-00543). Defendants are accused of infringing a patent generally related to a monitoring a device using self-learning rules (7,944,469). Olivistar’s complaints accuse defendants’ wrist bands that wirelessly monitor personal data including movement, caloric intake, and sleep patterns. The asserted patent originated with former operating company, Vigilos, Inc., and was assigned in 2010 to an unrelated entity, Vigilos, LLC, which is affiliated with IP Navigation Group, LLC (d/b/a IPNav). These suits appear to be the first time that the ‘469 patent has been litigated; the majority of Olivistar’s recent cases assert two other former-Vigilos patents that relate to network-based remote device control. 4/24, Texas Eastern District Court,
