By Lawrence Hurley WASHINGTON (Reuters) – The U.S. Supreme Court on Monday brought an end to Novell Incs antitrust claims against Microsoft Corp that date back 20 years to the development of Windows 95 software. By declining to hear Novells appeal, the court left intact a 10th U.S. Circuit Court of Appeals ruling from September 2013 in favor of Microsoft. The court of appeals unanimously affirmed the dismissal of Novell Incs claims that Microsoft violated the Sherman Antitrust Act when it decided not to share its intellectual property while developing its Windows 95 operating system. Novell was seeking more than $3 billion.
