This is so typical in technology now, large corporations patenting everything they can possibly think of, including things that they've blatantly copied. It absolutely doesn't surprise me that a technology as fundamentally simple and foundational as LIDAR is covered by a load of bullshit patents. As the article notes what this is really about is using your patents to litigate competitors either to slow their progress or force them into expensive fights that drain their resources. Frankly, patent reform is yet another case where the large players have built themselves a moat.
