A few months ago, an NFT group known as “Spice DAO” made the news for paying nearly $3 million at auction for a rare book of filmmaker Alexander Jodorowsky’s storyboards and concept art for a never-to-be-made adaptation of Frank Herbert’s epic science fiction novel Dune—and announcing their plans to use their purchase to make and sell their own adaptations and derivative works as well as copies of the book itself in NFT form. Of course, buying a copy of a book, no matter how rare, does not grant you the copyright or license to its contents. A clear gaff to be sure, which is then heightened by the fact that the purchase was funded almost entirely by investors and fans of the Dune franchise. But if purchasing a creative work does not give you rights to reproduce it, what does? We’ve put together this quick quiz to help you figure out when you do—and don’t—own the rights to a piece of intellectual property covered under copyright law.

It’s likely that you’ve heard about pop star Taylor Swift re-recording her old albums. Just a few weeks ago, she released Red (Taylor’s Version), a re-recording of her 2012 album Red. In April of this year, she released “Taylor’s Version” of her 2008 album Fearless. Why would a globally-known music star take the time out of her busy schedule to rehash her old music? The answer lies in the complex and little-understood realm of copyright law—and the issues that led to Swift’s undertaking are not only experienced by artists of her fame and status.
