> No Texas district is even in the top 5 for win rates for patent plaintiffs. You'd think if they were "in the pockets" of patent trolls, the trolls would achieve better outcomes there.

Not necessarily. If all the plaintiffs with poor-quality patents sue in that district (and they mostly do), those losing cases will pull down the patent plaintiff win rate for the district.

So it could still be the most patent-plaintiff-friendly district, even if the win rate is lower there.
