Digimarc Sues Shazam for Patent Infringement

Alleges That World`s Leading Mobile Music Discovery Application Infringes
Several Digimarc Patents
BEAVERTON, Ore.--(Business Wire)--
Digimarc Corporation (NASDAQ:DMRC) today announced it has filed a complaint for
patent infringement against Shazam Entertainment, Ltd. According to Shazam, it
is the world`s leading mobile music discovery provider, marketing software and
services that have been used by more than 50 million people in over 150
countries. Digimarc asserts that Shazam`s music identification technology
infringes three of Digimarc`s patents, including two patents dating back to
1995. Digimarc`s patents relate to technology that enables devices to identify
audio and visual content and immediately link the consumer to associated
internet services.

"We prefer negotiated business relations over litigation, but having not made
progress in initiating such discussions, we are heading to court to enforce our
patents," stated Bruce Davis, chairman and CEO of Digimarc. "While we are
comfortable seeking help from the courts to enforce our intellectual property
rights where they are not properly respected, our general approach is to foster
adoption of our technologies by establishing mutually profitable business
relationships in which we receive fair consideration for our innovations while
supporting continued progress toward the realization of a shared vision."

Digimarc has invented a range of technologies that employ cameras, microphones
and other sensors to enable instant identification of all forms of media
content. The contextual awareness of the phone combined with instant object
identification enables new, more efficient and higher quality methods to search
without text input. Applications like Shazam use Digimarc`s innovations to
provide more intuitive means for users to search for and get delivery of rich
Internet experiences.

The Complaint is filed in U.S. District for the District of Oregon, Civil Action
No. 3:09-cv-1355-KI.
