Philips sues Gillette over patents to electric toothbrushes
Royal Philips Electronics filed lawsuits in federal district court in Delaware and in the Landesgericht Dusseldorf in Germany against Gillette Co. for infringement of claims in patents directed to electric toothbrush technology.
Philips uses the technology in its Sonicare electric toothbrushes, which use microprocessors to direct bristle movement. The accused products of Gillette are electric toothbrushes sold under the Oral-B brand.
Philips received its patent for sonic technology in the United States in 1995 and another in Europe in 2000.
