Arbitron And Digimarc Square Off Over Technology Ownership
August 21, 2009 at 5:04 AM (PT)
ARBITRON is suing DIGIMARC CORP. seeking to invalidate nine patents covering technology involved in the PORTABLE PEOPLE METER, reports BUSINESSMIRROR.COM. DIGIMARC REPORTEDLY sent ARBITRON a letter in JULY, saying ARBITRON’s technique for detecting code embedded in radio broadcasts, PPM's technology, infringes on patents held by DIGIMARC.
ARBITRON has asked a judge to bar DIGIMARC from suing the company for infringement, according to a complaint made public in federal court in WILMINGTON, DE.
"ARBITRON has a reasonable apprehension of imminent harm that is sufficient to warrant issuance of a judgment that the DIGIMARC patents are invalid and/or not infringed," lawyers for the company said in the complaint.
The dispute, writes BUSINESSMIRROR, "centers on ARBITRON’s method for estimating the number of radio listeners through the use of its Portable People Meter, The meters are carried by listeners and pick up embedded codes identifying radio stations. DIGIMARC said in its JULY letter that its patents were infringed by the way the meters detect the codes."
"We’re aware of litigation and we’re in conversation with ARBITRON," said DIGIMARC Chief Legal Officer BOB CHAMNESS.
