This from Findlaw: Royal Philips Electronics has accused Gillette Co. of violating patents for its electric toothbrush technology. Philips, the Dutch electronics and technology conglomerate, uses the technology in its Sonicare electric toothbrushes, which use microprocessors to direct bristle movement. Boston-based Gillette sells its power toothbrushes under the Oral-B brand.
"We are confident that our Oral-B products don't infringe any Philips patents",said a spokesman for Gillette. Philips, who filed the lawsuits in federal district court in Delaware and in the Landesgericht Dusseldorf (Germany), said it received its patent for sonic technology in the United States in 1995 and another in Europe in 2000.
The IPKat assumes that, since US and European patent law remain out of line with each other even after TRIPs, it is necessary for Philips and Gillette to lock horns in both jurisdictions rather than just use one and treat it as a "winner take all".

It is also the IPKat policy that comments should not be made completely anonymously, and users should use a consistent name or pseudonym (which should not itself be defamatory or obscene, or that of another real person), either in the "identity" field, or at the beginning of the comment. Current practice is to, however, allow a limited number of comments that contravene this policy, provided that the comment has a high degree of relevance and the comment chain does not become too difficult to follow.
