It's obviously a port of sendmail written in Perl.
Has that been used in the past against a patent holder??
Not that I know of. "Slander of Title" is really a real estate law concept, however, SCO made an interesting attempt to use to enforce an alleged copyright claim. In their case, it turns out they didn't actually *have* the title they were claiming was being "slandered" by Novell. However, there really didn't seem to be anything fundamentally wrong with the reasoning - the consequences of claiming you own something you don't has substantial legal history behind it. In this case, it may actually require that MPEG-LA explicitly claim they "own" part of VP8, through a patent, in order to be actionable (assuming, of course, that the claim is false).
It is much harder to find a job than to keep one.
