Urban Dictionary defines a troll as someone "who posts deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument." The term copyright troll is now common amongst legal circles, and generally refers to someone who abuses copyright law for profit. Several high profile trolls and repeated bench slaps have helped bring attention to the copyright troll.
Then, three days later, the Ninth Circuit Court of Appeals issued an opinion concluding that Righthaven lacks standing to enforce copyright claims under the Copyright Act, making it the first court of appeals to decide the issue. The court's opinion is in line with almost every other district court that has looked at it. Righthaven's exploits have also been the subject of much online criticism. Righthaven's sole purpose was to acquire revocable rights to copyrights in order to sue copyright infringers. In theory, Righthaven's goal sounds almost noble. But in reality, it used the high statutory damages to scare unsuspecting bloggers into quick settlement, even if the bloggers would be entitled to fair use. But after more than three years of Righthaven's online reign of terror, the 9th Circuit decision makes it clear that Righthaven's business model does not work.
But even if these particular business models are dead, it doesn't mean that the copyright troll is dead. Copyright law, with the high statutory damages and little oversight, is still ripe for abuse.
