What is Public Domain

The term Public Domain refers to materials that are not protected by intellectual property laws such as copyright, trademark, or patent laws. The public owns these works, not an individual author or artist. Anyone can use a public domain work without obtaining permission, but no one can ever own it." Stim (2000). Most works of the Federal government are automatically in the Public Domain.
