That's trademarks, which so far have been more faithful to their stated goal of preventing consumer confusion, rather than creating new kinds of private property. For example, I don't need Apple's permission to use the trademarked word Apple, as long as I'm referring to the firm, or as long as I'm not using it in the context of electronics or music.
