To play devil's advocate, there is nothing about being a patent troll inherently illegal. Hotz feels the patent is invalid, but it might not be. Our system does not require you to ever build the object patented before extracting fees from it. This is in fact the way the US patent system works.
One of the patents is here: https://portal.unifiedpatents.com/patents/patent/10454707
Method, Apparatus and System for Retrofitting a Vehicle. This does in fact describe what Comma does. Looks like it might be infringing!
Now Comma must prove this patent cannot be valid.
We write open source ADAS software, and it doesn't have any functionality like that: https://github.com/commaai/openpilot
But for the purposes of attempting to extract a settlement, it doesn't matter. It will only matter after a long and expensive trial.
(I would like to invalidate the patent entirely, which several of their patents already have been. But even if it is valid, it also has to apply to us)
