Novell & Red Hat Win Legal Tussle Over UI Patents

Novell and Red Hat have won a legal battle over the infringement of user interface patents.

IP Innovation, a subsidiary of Acacia Research Corporation, brought the lawsuit against the software vendors in 2007, claiming they had infringed patents held by IP.

Novell and Red Hat allegedly infringed three of IP's patents, particularly U.S. Patent No. 5,072,412, with their Red Hat Linux, Novell SuSE Linux Enterprise Desktop and Novell SuSE Linux Enterprise Server products.

Despite attempts to prove its claims, IP Innovation LLC failed to convince the jury members in a Texan court, who ruled in favour of Novell and Red Hat.

The jury found that IP Innovation LLC had failed to provide sufficient evidence to prove its claims against the software vendors, said a report for Bloomberg BusinessWeek.

Michael Cunningham, executive vice president of Red Hat, said in a statement: “The jury knocked out three invalid patents that were masquerading as new and important inventions, when they were not.”
