A fourth NPE to receive patents formerly owned and asserted in litigation by Olivistar LLC, an entity managed by patent monetization firm IP Edge LLC, has now filed cases of its own. On August 31, 2016, Olivistar assigned the patent-in-suit (7,944,469) to Silkeen LLC, which has continued Olivistar’s campaign, albeit in a different market sector. Where Olivistar targeted fitness trackers, Silkeen has filed ten suits alleging infringement through the manufacture and sale of systems having environmental (i.e. temperature and humidity) sensors by defendants Cooper-Atlas, Grid Connect, L-Com, Mesa Monitoring, Monnit, National Instruments (Measurement Computing), Omega Engineering, Onset Computer, Primex Wireless, and TempAlert.
