SACRAMENTO — A small company trying to get its new flying disk off the ground is suing the maker of Frisbee for $100 million, charging trademark infringement and unfair trade practices.
The feud pits Sandeen Inc. of Hayward, Calif., and its SpinJammer disk against Wham-O Inc., which is marketing a similar new product called Ripspinner.
Wham-O, based in San Gabriel, is part of Kransco Manufacturing Co. of San Francisco.
A hearing is scheduled for Dec. 14 before U.S. District Judge Raul Ramirez on Sandeen's request for a preliminary injunction.
At issue is a flying disk designed with a cone-shaped center that enables it to be easily twirled on a finger.
Wham-O says it made disks with cones 20 years ago.
But Michael Sandeen of Walnut Creek, Calif., says he invented the product, which gained him publicity in People magazine last May. His sister, the company's chief administrative officer, says Sandeen Inc. may have to fold if it fails to obtain the injunction.
