I think the commenter's point was that simply having life tenure as a judge isn't the only potential motivation for their alleged bias toward patent trolls. That, in fact, their friends' and families' stakes in local businesses (e.g. the shell 'office' suites these patent trolls incorporate in) provide additional indirect motivation for the judges to keep the patent troll gravy train rolling.
Peer pressure, especially from close friends and family, and doubly in small towns, is incredibly motivating for most people.

I was not saying these offices are some kind of grift, just that these cases are a big part of the local economy. The backbone of related local cottage industry. And these types of offices are just one example of that industry that is so important to these judge's and jury's community.
