It matters. Of all possible patents to invalidate, why this one?

Uber - one of the world's most valuable private companies, doesn't need help with patent law.

Possible explanation: because this guy doesn't spend his day looking for patents to challenge; he read about that particular one on the news due to Waymo vs Uber case, and decided to take a look at it, only to notice it's bullshit.

That's the official story, but it also sounds pretty plausible.

Apparently they do considering they hadn’t submitted their own reexamination request of the patent in question that inevitably led to Waymo dropping the patent claim.
