It's like an unspoken, almost sacred concept in copyright law. It's the public domain, where cultural creations exist unfettered, without a legal owner (though often, a credited author). These works are free for use, reinterpret, and sell, and a protected place where orchestra conductors, curators, and preservationists frequently roam.

Which means, some old composer is now on equal footing with some other old composers, which is probably bad news for the 'cultural footprint'. "This is the same marketplace, of course, that exists for the music of Prokofiev's US contemporaries: works of Copland and Bernstein, for example, that enjoy copyright protection, but nevertheless appear regularly in the programs of US concertgoers."
But wait: isn't copyright (and broader intellectual property protection) about encouraging innovation, and protecting new works? That sacred thought has now been smashed, with the justices challenging the notion that the public domain is some irreversible territory. But the impact on newer authors, unfortunately, may effectively be nill. "The statute before us," Justice Stephen Breyer dissented, "does not encourage anyone to produce a single new work."
The court prioritized the alignment of US copyright law with international treaties, particularly those codified in the Berne Convention. But Breyer was worried about the implications of all of this. "If a school orchestra or other nonprofit organization cannot afford the new charges, so be it," Breyer continued. "They will have to do without — aggravating the already serious problem of cultural education in the United States."
