(Reuters) - Alphabet's Google LLC on Tuesday convinced a U.S. appeals court to cancel three anti-malware patents at the heart of a Texas jury's $20 million infringement verdict against the company.

The U.S. Court of Appeals for the Federal Circuit said that Alfonso Cioffi and Allen Rozman's patents were invalid because they contained inventions that were not included in an earlier version of the patent.
