As RPX reported last month, three new NPEs managed by Texas attorney Nicolas J. Labbit each acquired rights in at least one patent earlier this year. Tellus Fit, LLC has become the first of those newly formed entities to begin litigation, filing suit against thirteen defendants that make and/or sell exercise monitoring wearables, including Adidas, FitBit, LG Electronics, Microsoft, Motorola Mobility, Nike, Sony, and Timex. The complaints assert a single patent (6,976,937) generally related to a mobile exercise detection device that receives satellite positioning information.
