Eric Albritton, an East Texas lawyer who sued Rick Frenkel after he was revealed to be the author of the Patent Troll Tracker blog, has subpoenaed Google for (a lot) more information about both the PTT blog and popular patent law blog Patently-O. [InformationWeek via Patently-O]
The subpoena [PDF] requests documents relating to Google's communications with Richard Frenkel, Patently-O blogger Dennis Crouch, Mallun Yen (Cisco's chief patent lawyer), John Noh (Cisco spokesman now at Brocade), and Mark Chandler (Cisco GC and vocal patent reform advocate). It also asks for "all documents referring or relating to the establishment, creation, maintenance and financial support for THE BLOGS." (that would be Patently-O and PTT.) Albritton also wants documents about searches for himself and the ESN, LCC v. Cisco Systems patent lawsuit that he worked on, the subject of two allegedly defamatory posts.
Another interesting note: this lawsuit, in the East Texas town of Tyler, is on its third judge. Both Judge Michael Schneider (never mentioned on the PTT blog, as far as I know) and Judge Leonard Davis (who was mentioned more than once on PTT, and had an unflattering anagram of his name published) removed themselves from the case without explanation. The case now sits with Judge Richard Schell, who has indicated he will keep it.
