I meant from the opposite side--the person filing the complaint needs to be the copyright owner. Record companies and software publishers will often attempt to stop the sale of used (and 100% legal) products, but here in the US, the doctrine of first sale typically applies, even for products that are "licensed" and not "sold."
That's beginning to change, though, as online distribution takes hold. It's a great thing for publishers, as they can now control access to their works. I don't know why anyone hasn't challenged that yet by attempting to transfer ownership of a digital download from one party to another. Under current US law, it should be entirely possible and legal to do so, but the companies that provide the content do not provide the means. They also don't provide warranties. Have you ever tried recovering a lost key or damaged bit of DRM from a content distributer? The US, at least, needs change in the area. Consumer, i.e. individual, rights are not being properly represented and protected.
