Two years after a court in Sweden affirmed his conviction for copyright law violations and sentenced him to eight months in prison, police arrested Peter Sunde, one of the founders of a popular website frequently accused of copyright infringement. Sunde and three others were convicted by a Swedish court in 2009 of assisting the distribution of illegal content online. Copyright infringement is generally treated as a civil claim, but the laws in the United States and other countries provide for criminal penalties in certain circumstances. Sunde's case relates to the growing legal field of cybercrime because of the internet's potential for wide distribution of infringing materials.
The Pirate Bay website allows users to download media, including movies, video games, and music, using BitTorrent, a peer-to-peer network protocol that allows people to distribute large amounts of data over the internet. Critics allege that this, much like other services that came before it, has led to massive amounts of copyright infringement. Other popular websites that allegedly serve similar functions have also been the subject of criminal investigations and prosecutions, including the raid on the New Zealand home of Kim Dotcom, the proprietor of the now-shuttered MegaUpload website.
In the U.S., federal copyright law includes both civil and criminal methods of copyright enforcement. Remedies in civil claims include injunctive relief and monetary damages, and a plaintiff is not necessarily required to prove that the defendant deliberately infringed a copyright. Criminal copyright claims have a much stricter burden of proof regarding a defendant's mens rea, or state of mind. Prosecutors must prove beyond a reasonable doubt that the defendant acted "willfully" to infringe a copyright. 17 U.S.C. § 506, 18 U.S.C. § 2319.
