This past week, Richman Technology Corporation filed suit against Alphabet (Google) (6:20-cv-00769) and Samsung (6:20-cv-00770) after hitting ADT (1:20-cv-00979), Hangzhou Hik-Vision (Hikvision) (2:20-cv-07375), and Robert Bosch (6:20-cv-00758) earlier in August. The inventor-controlled plaintiff asserts against each defendant up to four patents, in overlapping sets, from five at issue across the campaign, the patents generally related to a security system that uses various sensors and devices (including cameras, radio frequency tracking devices, climate control and AC systems, elevators, and energy sensors) to detect site conditions and alert a security guard as needed. In its latest complaints, Richman targets various smart home and security systems.
