As this place in Texas has over the last 10 years built an industry around the IP cases going to trial there (with e.g. short-term office rental rates as high as in NYC) - maybe those are cases that are not "supporting" their continuing gold rush.
None of that of course touches on the fundamental flaw in the system that IP cases are so exorbitantly expensive that most have to pay those modern "highwaymen" even when knowing that their demands are most of the time completely without base and are solely a legalized form of extortion.
Just consider how you feel, when you worked for years and developed / invented a large scale real-world solution and those crooks with IP / patents originally being provided to protect their work on bicycles and abacuses are lining up outside your office all claiming that they would have done all the work.
So the first step to cure this must be a protection of business that have invested substantial time and money into their products, are bona fide and actually running a business based on their work, to be able to defend themselves against such frivolous law abuses.
