In Troll Tracker Lands Job Fighting Patent Trolls!
, I noted the defamation suits filed against "Troll Tracker," aka Rick Frenkel, by two Texas lawyers, in the aftermath of Frenkel's identity being revealed, after bounties put up by one of the subjects of his criticism, patent attorney Ray Niro. (Whew! It's convoluted, but all you need to know is that Frenkel is the good guy here.)
An update on the status of those two (to my mind, ridiculous) cases can be found in Troll Tracker defamation update: Cisco wants to see tax returns, evidence of 'mental anguish'. Reading through all this--it's hard to see how anyone can believe (a) patent law is grounded in justice; or (b) a state-run "justice" system can ever be, well, just.
