U.S. top court rules against Alice Corp over software patents

WASHINGTON (Reuters) - The U.S. Supreme Court on Thursday ruled that implementing an abstract idea using a computer does not make an invention patent eligible.

On a 9-0 vote, the court ruled for CLS Bank International, which challenged patents held by Australia-based Alice Corporation Pty Ltd. The court added some clarity to a confused area of the law concerning when software can be patented.
