28 April 2003 Linthicum, MD Lightwave -- CIENA Corp., provider of intelligent optical networking systems and software, announced that a jury for U.S. District Court for the District of Delaware today issued its verdict in favor of CIENA in its litigation against Corvis Corp. for patent infringement.

The jury found that Corvis' CorWave system infringes CIENA's U.S. Patent No. 5,504,609 titled "WDM Optical Communication System With Remodulators," which covers optical communication technology that CIENA claims to have pioneered.

CIENA's suit alleged Corvis' infringement of four CIENA patents for optical transport technology. In a February 2003 trial, a jury found that one of these patents was infringed and that two were not infringed, but the jury was deadlocked on the fourth patent. Today's verdict in favor of CIENA was the result of a retrial specifically for the fourth patent. CIENA plans to move for an injunction prohibiting sales of infringing products.
