A complaint filed Dec. 22 in the U.S. District Court, District of Colorado, Nautilus Inc. alleges Keys Fitness has infringed several patents owned by Nautilus related to indoor exercise bikes.
The complaint, which requests a jury trial, stated that Keys infringed on three Schwinn indoor cycle patents for variations on a free wheel clutch mechanism. Nautilus acquired the patents when it acquired Schwinn Fitness in 2001.
Nautilus in the court documents also stated that it informed Keys of the alleged infringements in a letter dated May 30, 2006.
Nautilus requests Keys be enjoined from further infringement, be required to pay damages, and be ordered to pay the costs of the court action and attorney fees.
No response had been filed by Keys in the court action that was filed immediately prior to the long Christmas weekend and holiday week, although the court did not log it into the court system until Dec. 26.
