CHICAGO (Map) - CHICAGO, March 20 /PRNewswire-FirstCall/ -- Card Activation Technologies (OTC Bulletin Board: CDVT), owners of a patent covering a method for the activation and processing of transactions related to debit styled cards, which include gift cards, phone cards and other stored value cards, announced today that the United States District Court for the Northern District of Illinois ruled that Card Activation's Patent, U.S. Patent Number 6,032,859, is valid.

The court issued its ruling in response to a motion to declare the patent invalid that was filed by Barnes & Noble Inc. (NYSE: BKS) and Aeropostale Inc. (NYSE: ARO).

Card Activation will soon issue full details of the court's ruling.

Card Activation Technologies, Inc. is a Chicago-based company that owns proprietary patented payment transaction technology used for processing gift cards, phone cards and other debit purchase transactions. The Company is actively seeking to license its technology to the thousands of current users and believes that many retailers, gas stations, phone companies and others that utilize those stored value cards, such as gift and debit, infringe its patent. As a result, the company is aggressively pursuing litigation against these infringements. The Federal Reserve Bank of Philadelphia estimated the prepaid card market to be valued in excess of $181.7 billion in transactions in 2006. According to market forecasts, the prepaid industry will grow to $421.5 billion by 2010. For further information about Card Activation Technologies go to http://www.cardactivationtech.com .
