Facebook and three other social media companies are facing a blast of patent infringement claims in California from a nonpracticing entity with ties to IP Valuation Partners.

Corrino Holdings LLC sued Facebook Inc.; Facebook subsidiary Instagram Inc.; Snap Inc.; and Foursquare Labs Inc. on Oct. 4. Corrino is asserting patents related to search, GPS location services and social media usage metrics. The suits generally accuse the social networks of infringing when they notify users of nearby services or enable search within a geographical range.
