SimpliSafe filed a complaint against SkyBell, SB IP Holdings, LLC, and Eyetalk365, LLC, seeking declaratory judgment of noninfringement and invalidity of U.S. Patents 10,674,120, 10,523,906, 10,200,660, 10, 097, 796, 10,097,797, 9, 485, 478, and 9, 432,638. SimpliSafe is a Boston-based security system company that specializes in DIY/self-monitored security systems. SimpliSafe says that the defendants accused SimpliSafe’s Video Doorbell Pro and SimpliCam of infringing the subject patents by letter of December 16, 2020. The defendants also petitioned the ITC to institute an investigation relating to the importation of the accused devices in December. The asserted patents are directed to video doorbells and cameras that can be viewed via smartphones and the like, and permit livestreaming from the cameras. According to the complaint, while the patents claim pendency to a 2002 provisional application, there was a break in the chain of co-pendency that results in all of the asserted patents being not entitled to claim priority to that date, meaning that the applications filed prior to the break serve as prior art to the asserted patents. SimpliSafe asserts that this results in the patents being invalid, and separately asserts that the accused products do not infringe the patents.
