Those are kind of high. Did they actually charge those rates? Or retroactively bumped up the rates once they knew the case was dismissed?
Junior and mid level associates (400-650 an hour) do most of the heavy lifting. Partners are more supervisory, but will be do a lot for depositions, hearings, negotiations and trials.
Even a relatively small case against Acacia costs like 1.5-2 mil.
Quite often partners in big firms make more than that
Depends on what you need done. Legal work is expensive but you have to look at the leverage/productivity multiplier of their output.
