Patent infringement award against Magnetek upheld

A $22 million patent infringement arbitration award against Menomonee Falls-based Magnetek Inc. has been upheld. The company plans to appeal. The arbitration began in 2004 and centers on electronic ballasts that Magnetek formerly used on some of its products. The company said last year that it had $22.6 million set aside to pay the arbitration award, if necessary. Magnetek is a manufacturer of digital power and motion control systems used in material handling, communications and energy delivery.
