A company which allowed customers to resell their digital music "second hand" breached copyright, a US judge has ruled.

ReDigi billed itself as the first legal way to resell music bought online - but soon provoked the ire of record labels.

It was sued by Capitol Records in January 2012, and on Monday a New York judge said ReDigi was making unauthorised copies of music.

The ruling could have broad implications for digital reselling.

...

In the digital world, where duplication is much easier, the first sale doctrine was not appropriate, the judge said.

"It is simply impossible that the same 'material object' can be transferred over the internet," he wrote in his ruling.

...

ReDigi's software is designed to prevent sellers from reinstalling a sold song to their computer, and offers users the chance to check their libraries for illegal music.

But the judge said: "It is beside the point that the original phonorecord no longer exists. It matters only that a new phonorecord has been created."
