A judge in Delaware’s federal District Court has put the brakes on a patent troll’s carpetbombing of the radio industry. For those just tuning in, some ambiguous firms in Delaware acquired some old AT&T patents that vaguely describe digital data transmission. Armed with these, the firms filed a slew of lawsuits in 2013 against broadcasters who’ve deployed HD Radio technology, claiminng that the system infringes on their intellectual property.
iBiquity Digital Corporation, HD’s proprietor, filed a counterclaim last year seeking the dismissal of the trolls’ crusade and the voiding of its patent claims. If the trolls want to bilk anybody, iBiquity is the logical target, as it controls all of its intellectual property with a firm hand. Furthermore, the station’s license agreement with broadcasters indemnifies stations against such claims.
