A Delaware
company has sued a large number of radio broadcast groups alleging patent
infringement for using its technology for their HD Radio broadcasts, according
to RadioWorld.
The filing last Friday by Wyncomm LLC claims the
broadcasters are using In-Band On-Channel technology and therefore infringing
on U.S.
patent no. 5,506,866 and several associated patents. It lists Delaware Radio
Technologies (DRT) as the exclusive licensee for the technology.
HD Radio developer iBiquity Digital is not named nor
identified in any of the lawsuits. The company, which declined comment on the
suits, licenses the HD Radio technology used by the radio broadcasters.
The Nov. 1 filing in U. S. District Court in Delaware names
Beasley Broadcast Group, CBS Radio, Clear Channel parent CC Media Holdings, Cox
Media Group, Cumulus Media, Entercom, Entravision, Greater Media, Hubbard
Radio, Radio Disney, Radio One, Saga, Townsquare Media and Univision as
defendants in the federal lawsuit.
Wyncomm is asking for a jury trial and is seeking damages
from the broadcasters.
