US copyright legislation in the form of the Digital Millenium Copyright Act (DMCA) offers a degree of protection against legal liability if their services are misused by customers for illegal file sharing or other activities which infringe copyright. However the 1709 Copyright blog reports a recent case in which an internet service provider (ISP), Cox Communications lost an appeal against an award of US$ 25 million to a music rights management company, BMG. In this case the ISP had failed to do enough to try to stop the online infringement in music and films. The eastern Virginia District Court found that in the circumstances Cox Communications could not claim the “safe harbor” protection afforded to ISPs in the US legislation. This is an interesting example of the large sums which can be involved in cases of copyright infringement on a commercial scale.
