 Utility Patent 

A utility patent differs from a design patent in that it protects the mechanical, electrical or chemical aspects of an invention. Utility patents also may cover newly discovered uses of a known drug, methods of using an apparatus or using a chemical composition; articles of manufacture; a new process; certain methods of doing business; and software source code.

A design patent is more limited in its protection. It only covers the "ornamental" aspects or "look" of an item, not its utilitarian or mechanical aspects, described above.
