Whats the difference between a design patent, a provisional patent, and a utility patent?
A design patent protects non-useful, ornamental designs and lasts for 14 years. A provisional patent does not really exist – it is a provisional patent application, which waits for perfection into a utility patent application for up to one year, during which time you may label your invention as “Patent Pending.” The Utility patent is the traditional “patent” for a new, useful and non-obvious invention. It lasts for 20 years from the date of filing, but in no instance less than 17 years from the date of issue.
