Can you point me to the US Supreme Court case where this is existing law?
It's pretty clear that if you have a physical copy of a book, you can lend it to someone. It also seems pretty reasonable that the person borrowing it could make fair use of it, e.g. if you borrow a book from the library to write a book review and then quote an excerpt from it. So the only thing that's left is, what if you do the same thing over the internet?
Shouldn't we be able to distinguish this from the case where someone is distributing multiple copies of a work without authorization and the recipients are each making and keeping permanent copies of it?
Also, I don't quite understand how your example is relevant to the case. If you give a book to a friend, they are now the owner of that book and can do what they like with it. If you photocopy that book and give them the photocopy, they are not the owner of the book and you have reproduced it without permission. The same is, I believe, true of digital copies - this is how ebook libraries work.
In this case, Anthropic were the legal owners of the physical books, and so could do what they wanted with them. They were not the legal owners of the digital books, which means they can get prosecuted for copyright infringement.
We're talking about lending rather than ownership transfers, though of course you could regard lending as a sort of ownership transfer with an agreement to transfer it back later.
> If you photocopy that book and give them the photocopy, they are not the owner of the book and you have reproduced it without permission.
But then the question is whether the copy is fair use, not who the owner of the original copy was, right? For example, you can make a fair use photocopy of a page from a library book.
> They were not the legal owners of the digital books, which means they can get prosecuted for copyright infringement.
Even if the copy they make falls under fair use and the person who does own that copy of the book has no objection to their doing this?
If you photocopy a single page from a library book, this is often (but not always) fair use because you're copying only a limited part of the book. In the same way, you can quote a section or paragraph of a book under fair use. You cannot copy the whole book, though. Therefore:
> Even if the copy they make falls under fair use and the person who does own that copy of the book has no objection to their doing this?
If the copy had been made under fair use, then yes, this wouldn't be illegal. But it wasn't, because it was a reproduction and distribution of the entire book by someone who did not have the right to do that.
I understand that some of these things might be confusing to you, but Anthropic is absolutely within the position of being able to afford attorneys and get good advice as to what they could legally. I hope you also understand that good legal advice isn't being told what you want so you can do the thing you want to do without any regard for what are likely outcomes.
With that in mind, what do you think the inconsistency is between ReDigi and Sony?
