Trend Micro says court confirms invalidity of patent claims asserted by IV
Trend Micro Incorporated applauds the recent ruling of the Federal Circuit Court which confirmed the invalidity of patents asserted against Trend Micro by Intellectual Ventures. Following a ruling by the U.S. District Court of Delaware annulling Intellectual Ventures' claims, IV appealed to the Federal Circuit Court, which has now affirmed the District Court's initial ruling. IV initially sued Trend Micro for infringement of various claims of U.S. Patent Nos. 6,460,050 and 6,073,142, seeking $150 million. IV asserted two other patents, but Trend Micro was able to get IV to drop those patents because IV likely believed them to not be infringed or invalid. IV in fact dropped one of those patents during the pendency of its patent ineligibility motion. The district court of Delaware declared the claims of the two remaining patents to be asserted, the '050 and '142 patents, to be patent-ineligible. The '050 patent allegedly related to generating a digital identifier for email messages through a method of filtering. The '142 patent allegedly described an "automated post office" which allows for the analyzing and filtering of vetted emails recognized to be unsafe.
