Google's X Development labs originally focused on secret projects, including Google's self-driving car project, Waymo. Waymo eventually spun out into its own entity (wholly owned by Google, and now by Alphabet). Waymo and Google submit most of their applications with non-publication requests, leading to a smaller picture of the total amount of documents assigned to Alphabet companies within the sector. Interestingly, though Waymo was started in 2009, most of the patent activity doesn't have any priority before a couple years after Waymo spun out, which is later than most established companies who are active in this sector. It uses image-processing algorithms to interpret data collected by sensors on the vehicle and utilizes LiDAR sensors to better enhance driver safety.
