Maguire Products Files Suit Against Comet Automation Systems For Infringement Of Patents and Microblender (TM) Trademark



DAYTON, OHIO, U.S.A, June 6, 2003: Maguire Products, Inc., the world's largest manufacturer of gravimetric blenders for plastics processing, announced it filed suit against Comet Automation Systems, Inc., alleging patent and trademark infringement and unfair competition in connection with a small-volume gravimetric blender of the type Maguire Products manufactures and markets under the trademark MicroBlender (TM).

The suit alleges that a blender sold by Comet infringes Maguire Products' U.S. Patents D424,587 (issued in 2000) and 6,467,943 (issued in 2002), which are directed to the Maguire Products MicroBlender product. Maguire Products' suit also alleges unfair competition by Comet and infringement of the Maguire Products trademark MicroBlender, which Maguire Products has used since 1997, by Comet's use of the mark "GraviMix Micro blender."

The suit was filed on Wednesday 4 June in the United States District Court for the Southern District of Ohio at Dayton, Ohio, close to Comet's headquarters.

Maguire Products promotes its MicroBlender gravimetric blender as one of the smallest, if not the smallest, gravimetric blender available to the plastics industry, particularly adapted for use with small processing machines or ones with low throughputs, such as injection molding machines running 140 lb. (64 kg) per hour or less.

"The Maguire MicroBlender gravimetric blender incorporates several unique design elements associated with its small size and furnishes the high level of precision required for mounting on small processing machines," said B. Patrick Smith, Maguire's vice president of marketing and sales. "These include a special high-accuracy system for dispensing minor blend ingredients such as additives and colorants, vibration management technology to eliminate false weight readings caused by machine shock or vibration, light weight and reduced footprint for installation on the smallest molding presses, and hand removability of all four hopper bins to facilitate frequent job and color changes."

The Maguire Products MicroBlender (TM) gravimetric blender was invented, designed and developed by Steve Maguire, president of Maguire Products, Inc. Approximately 2,150 Maguire Products MicroBlender gravimetric blenders are in commercial use around the world.
