Habeas sells an anti-spam solution consisting of a copyrighted and trademarked Haiku.  The Haiku must be appended to an email in order to pass through a Habeas spam filter.  Thus mis-use of the Haiku, Habeas argues, is copyright and trademark infringement.  Habeas has now announced the first batch of copyright and trademark suits against spammers who allegedly mis-used the Haiku.
