Utility patents are available for processes, machines, manufactured items, and compositions of matter. The utility patents last 20 years from the effective filing date. Design patents protect the overall appearance of an invention and are for “ornamental” designs for articles of manufacture. A design patent lasts 14 years from the date it issues. There may be overlap between design patent protection, copyright and trade dress protections.
