Daniel Nazer on the EFF:
We’d like to enlist your help to fight this troll. One way to defeat a troll is to prove—either in court or at the patent office—that the claimed invention was not new (or was obvious). In other words, show that the patent applicant didn’t really invent anything. To do this, we need to find publications from before October 2, 1996 that disclose similar or identical ideas (this also known as prior art). The best prior art will include publications describing early versions of podcasting or any other kind of episode distribution over the Internet.
I;m drawing a blank, but I’m sure there are others out there who can help.
