Impact Engine, Inc. has filed suit against Alphabet (Google) (3:19-cv-01301), alleging that the tech giant has infringed all six members of a family of patents generally related to a “multimedia communication system” that comprises a template repository and an interactive “project builder”. The Southern District of California complaint alleges multiple interactions between the two companies beginning over a decade ago, during which Impact Engine purportedly disclosed its “proprietary Flash Ad Engine” and demonstrated “a Google-specific prototype” built upon request and after which Google released its Display Ad Builder product. The plaintiff accuses Google of infringement through the provision of its advertisement platform (e.g., Google Ads, AdSense, AdWords, Display Ad Builder, Display Network, Doubleclick, Marketing Platform, and Web Designer).
