Document Security Systems Announces Third Delay in Patent Validity Decision by French Court.

Court Reschedules Release of Decision to January 9, 2008

ROCHESTER, N.Y. -- Document Security Systems, Inc. (AMEX: DMC) ("DMC"), a leader in proven, patented protection against counterfeiting and unauthorized copying, scanning and photo imaging, announced today that the Tribunal de Grande Instance de Paris, 3rd Chamber - 3rd Section of the High Court of Paris in Paris, France, has rescheduled the release of its decision on the validity in France of the Company's European Patent No 0455750B1 (the "Patent"). The judgment, which will be the outcome of a one-day hearing held on June 4, 2007, is now scheduled for January 9, 2008. The court did not provide an explanation for the delay.

Patrick White, Chairman and CEO of Document Security Systems, commented, "I can assure our shareholders that the French postponement has no bearing on our pursuit of an infringement proceeding in Germany where our patent has been deemed valid by the German national courts. We are aggressively working with our lawyers to complete the necessary infringement research prior to the actual filing of the suit. Let me be clear, this is a delicate time in the process. Communications are ongoing at a high level, and shareholders should not confuse lack of news with lack of activity. We remain open to negotiations as our stated goal is a going-forward agreement utilizing DSS' newer and more effective technologies. The infringement process remains intact and we are continuing to pursue the enforcement of our intellectual property rights."

On August 1, 2005, DMC filed a patent infringement suit in the European Court of First Instance ("CFI") against the European Central Bank ("ECB") alleging that the Euro banknotes produced by the ECB infringe DMC's the Patent. Subsequently, DMC received notice that the ECB had filed a claim to invalidity with patent courts in France, Germany, the United Kingdom, the Netherlands, Austria, Italy, Spain and Belgium. To date, the Patent has been validated in Germany, and the Company is appealing a ruling in the U.K. in which the Patent was held to be invalid. The CFI ruled on September5,2007 that it was not the correct venue for infringement proceedings, which has opened the door for country-by-country infringement litigation.
