NEWPORT BEACH, Calif.--(BUSINESS WIRE)--Jan. 17, 2006--Acacia Research Corporation (Nasdaq:CBMX)(Nasdaq:ACTG) announced today that the 2006 Defense Appropriations Bill, recently signed by President Bush, includes an allocation of $2.4 million to fund efforts by CombiMatrix to develop further its microarray technologies for the detection of biological and chemical threat agents. Since March 2004, CombiMatrix has been awarded a $5.9 million contract, a $2.1 million contract that is currently in process, and today’s announced allocation of $2.4 million for its detection technologies. Under previously funded programs with the US government agencies including the Department of Defense, CombiMatrix demonstrated that its microarray could be multiplexed for the simultaneous detection of toxins, viruses, and bacteria using immunoassay and genomic analysis. Unique to this platform is “on chip” electrochemical detection, which eliminates the need for a large, complex and expensive optical system.
