(afaik) what makes this newsworthy is that this is the first lawsuit filed by motorola since it was purchased by google
In a literal sense, you are correct. But don't ignore the fact that there had to be a group of lawyers and execs in a room at the GooglePlex that gave this move a green light. This is why Google bought Motorola.
Right. Google and Motorola are too separate corporate entities.
I presume this was a sarcasm here?
It is factually right, they are separate entities.
It's just that one entity is under significant influence of the other. Doesn't change the fact, that yes, they are separate.
