A district judge in California invalidated four patents owned by Bascom Research, LLC, a subsidiary of Document Security Systems, Inc., ruling the asserted claims of the patents-in-suit unpatentable under Alice (7,111,232, 7,139,974, 7,158,971, 7,389,241). Judge Susan Illston’s decision grants motions for summary judgment filed by Facebook and LinkedIn, the only remaining defendants in a campaign that Bascom initiated in 2012.
