A federal court has ruled in favor of Islandia-based CA Inc. over a patent challenge, according to the company.

In 2002 Canadian software developer Simple.com threatened CA with a patent infringement suit over its Web-based software. But CA filed a pre-emptive federal complaint in 2004 seeking a declaration of "non-infringement and invalidity" to the claims.

In a statement released Wednesday, CA said the U.S. District Court for the Eastern District of New York, in Brooklyn, ruled that CA did not infringe on three patents held by Simple.com.

CA, represented by Covington & Burling, said its victory "sends a clear message to those who would file patent claims against CA that it will vigorously protect its rights and seek appropriate legal remedies."
