Business Wire, Oct 29, 2008

NEWPORT BEACH, Calif. -- Acacia Research Corporation (Nasdaq:ACTG) has been named to Deloitte's prestigious Technology Fast 50 program for Orange County, a ranking of the 50 fastest growing technology, media, telecommunications, and life sciences companies in the area. Rankings are based on the percentage revenue growth over five years from 2003 - 2007.

Acacia Research's increase in revenues from $692,000 in 2003 to $52,597,000 in 2007 resulted in a number 4 ranking in the Technology Fast 50 for Orange County based on a 5-year growth in revenues of 7,500%.

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 2003 and $5,000,000 in 2007, be headquartered in North America, and be a company that owns proprietary technology or proprietary intellectual property that contributes to a significant portion of the company's operating revenues; or devote a significant portion of revenues to the research and development of technology. Using other companies' technology or intellectual property in a unique way does not qualify.
