What about that Texas county that was a favorite of patent trolls, was that ever resolved somehow? I remember the XPlane creator was sued for patent violations and he went to the listed headquarters of the company and it was just an empty office in Texas. There were many companies that listed the same empty office as their headquarters, like, hundreds of companies with the same run-down empty "headquarters".
