Icon Health & Fitness has filed its fourth suit against Peloton Interactive in the U.S. federal court in Delaware, where two other suits filed last year are still pending. This time, Icon is attacking the Auto Follow feature of Peloton’s new Bike+ model, which automatically adjusts its resistance to match an instructor’s call-out. Claiming that it infringes its patent N° 10,864,407, Icon says it had developed its own basic interactive connected technology, called iFit, twelve years before Peloton was founded, displaying it in the late 1990s at the Atlanta Super Show. Among other things, Icon is also challenging the swiveling screen on Peloton’s Bike+, stating that it infringes on a pending patent. Icon is seeking a finding of infringement, an injunction, damages and fees.
