Canadian Court Declares Calgon Carbon Patent Invalid
PITTSBURGH, PA – 11/15/2006
Calgon Carbon Corporation (NYSE: CCC) announced today that the Federal Court of Canada found that the company’s Canadian patent for the use of ultraviolet light to prevent infection from Cryptosporidium in drinking water is invalid.
The trial judge’s ruling followed a trial in April 2006 in which Calgon Carbon alleged that the City of North Bay, Ontario, Canada infringed its patent for the use of ultraviolet light to prevent infection from Cryptosporidium in drinking water and that Trojan Technologies Inc. induced or procured North Bay’s infringement. In his ruling on the case, the judge found the patent invalid because it was “. . . anticipated by the prior art.”
Commenting on the ruling, John Stanik, Calgon Carbon’s president and chief executive officer, said, “We are clearly disappointed in the judge’s decision, and we are evaluating our options with respect to this decision.”
Calgon Carbon Corporation, headquartered in Pittsburgh, Pennsylvania, is a global leader in services and solutions for making air and water cleaner and safer.
