Program with CombiMatrix Technology 
NEWPORT BEACH, Calif.--(BUSINESS WIRE)--May 17, 2006
Acacia Research Corporation (Nasdaq:CBMX)(Nasdaq:ACTG)
announced today that its CombiMatrix group will collaborate with EAI
Corporation, a subsidiary of Science Applications International
Corporation (SAIC), for field deployment of CombiMatrix's
influenza-screening technology for the identification of all versions
of influenza A, including the highly pathogenic Eurasian (H5:N1)
Funding for this program will be provided by the Center for
Innovative Technology/Institute for Defense and Homeland Security
through its Partnership Intermediary Agreement with the Department of
Defense. Additional partners in this project include the San Francisco
Bay Estuary Field Station of the US Geological Survey/Western
Ecological Research Center and the Prince William Sound Science Center
of Cordova, Alaska. 
"The US government continues to be justifiably concerned about the
entrance of highly pathogenic avian influenza into North America, and
CombiMatrix continues to demonstrate the power of its technology in
this realm," stated Dr. Amit Kumar, President and CEO of CombiMatrix.
"This collaboration with EAI gets our technology into the field and
into the hands of people and groups standing watch on US soil. This
program is in addition to our participation in the US Government's
National Early Detection System." 
"We are pleased that the Institute for Defense and Homeland
Security has agreed to fund this combined effort with CombiMatrix,"
said Dr. Joe Dudley, Chief Scientist at EAI. "We believe that the
CombiMatrix system is a powerful, versatile, and portable system for
influenza monitoring. We believe that this approach, combined with
EAI's mobile-laboratory products and expertise, will provide a very
powerful tool for monitoring and preparedness in the event of a
