Alarm.com (6:22-cv-01165) is the latest defendant to be sued in the litigation campaign that inventor-controlled Richman Technology Corporation launched in August 2019 with a suit against Skylink Technologies. In the new complaint, the plaintiff asserts a single patent generally related to a security system that uses a “checkpoint system” to analyze sensor data and alert users of an ongoing event. Alarm.com is accused of infringement through the provision of its Smart Home Solutions platform, with certain notification alert tools at issue.
