U.S. top court turns away Google fight over business patents

April 30 (Reuters) - The U.S. Supreme Court on Monday declined to hear Google's appeal of a lower court's ruling that narrowed the scope of patents that can be challenged before a federal tribunal whose proceedings have led to the cancellation of many patents.

The justices let stand a 2016 federal appeals court ruling against Google, a subsidiary of Alphabet Inc, which had successfully challenged at the U.S. Patent and Trademark Office a patent it was accused of violating. The appeals court said the patent had been wrongly reviewed in a proceeding reserved for business-related patents.
