“Under the U.S. Copyright Act (in contrast to many copyright regimes in Europe), once a piece of art is sold all rights to the physical work belong to the buyer. No matter how much the art appreciates in value, artists aren’t due a penny when the work is resold. All of the profits belong to sellers, not to creators.There is only one exception to that rule in the United States: the 1977 California Resale Royalties Act, a so-called droit de suite law that grants artists a continuing interest in their work when it changes hands.” Now a judge has said the California law is unconstitutional – sorry, artists.
