Another recently formed subsidiary of Monument Patent Holdings, LLC has filed suit. First-Class Monitoring, LLC’s new complaint asserts a single patent (6,014,089) generally related to the digital transmission of information using the short message service (SMS) portion of a personal communications system network. The NPE accuses CalAmp (2:16-cv-01211) of infringement through provision of its LMU-800 vehicle tracking product, which it contends sends text messages through a GSM network to convey “movement and position data”.
