Copyright law protects all original works regardless of whether these works are published or have commercial value.
Copyright applies to literary, dramatic, artistic, and musical works as well as performances, sound recordings, and communication signals. (Examples: a song, a novel, a play, a computer program)
Copyright does not apply to the title for a song, the ideas for a plot, a method of staging a play, works in the public domain (i.e. Shakespeare because he has been dead for more than 50 years), the facts in an article, and the name of a program (unless protected as a registered trademark). |
