Supreme Court won’t review $31 million award against Demant and Widex in patent case

WASHINGTON, DC—The U.S. Supreme Court announced on April 22 that it would not hear an appeal of a Federal District Court verdict against the Danish hearing aid manufacturers William Demant Holding A/S and Widex A/S in a patent case brought by Energy Transportation Group. The high court’s decision leaves standing a jury’s $31 million verdict against Demant (which owns Oticon) and against Widex.

In a suit filed June 23, 2005 in U.S. District Court in Delaware, Energy Transportation Group alleged that the defendants had infringed on a patent it held for technology that reduces hearing aid feedback.

    Bob B.,

    You are quite right that William Demant does not own Widex and I did not intend to say that it does–though I can see why you read the post that way. I have revised it for greater clarity so that it now says:

    The high court’s decision leaves standing a jury’s $31 million verdict against Demant (which owns Oticon) and against Widex.

    I urge you and other readers to read my colleague Holly Hosford-Dunn’s May 1 post on her Hearing Economics blog, which provides much more comprehensive coverage of this important issue. The URL for that post is
