In Brave New World (1980), it appears as though anything created by those below anyone is owned by those at the very top. This is best displayed in a scene at the beginning of the film (14:00), where Helmholtz Watson is showcasing his newest film to the most powerful character in the movie, Mustapha Mond. This video is called "Planned Perfection", and it goes over the indoctrination techniques of children. After being showed it, Mond states that he's glad he got to see it before it's permanently deleted and erased. Mond states that it contains information and ideas the general populous should not be shown, even though Helmholtz thought he was very careful. In the end, Helmholtz has no say in what happens to his work, and it is lost forever. In this world, no one earns money per say, as everyone works their share and earns their rations based on their class. Therefore, there isn't much need to protect intellectual property rights in relation to money.
It does appear that works are still attributed the the person that created them, as is shown towards the end of the movie (2:48:56) with a filmmaker creating and displaying a film, but everything is still controlled by the very top. That filmmaker discusses his creation with Mond before it's published, a conversation in which Mond, without much subtlety, sends the filmmaker in a specific direction with the films overall vibe in order to control the masses. If that film did not fit his vison, he wouldn't of hesitated to have it deleted like Helmholtz's at the beginning of the movie. This all checks out with your average authoritarian society, where the supreme leader is the one in control of all information and creations within their society.
Even creations of the past are heavily censored if not erased entirely. One of the key traits of John the Savage is his constant quotation of William Shakespeare plays. While living on the savage reservation, one of if not the only book he had access to was the works of Shakespeare, so a lot of his dialect came from it. When he enters the brave new world, everyone who lives within it find everything he says odd and peculiar, because none of them have ever read a word of Shakespeare. Everyone except Mustapha Mond, of course. He owns copies of many old world works that only he has read, seeing as he believes the works contain ideas he doesn't want his civilians to have. Many of these works are in the public domain today, but in the brave new world it appears that they are simply in Mond's domain. As I mentioned earlier, this is a classic authoritarian government in which only information Mond wants the people to know is released.
