various types of patents

A utility patent protects the best way something is used and the ins and outs, say for example a process or article of a process, a product, or composition of matter. Utility patents are exactly what they appear for the reason that they literally are aimed at an invention that has a useful function or purpose for instance a new power hand tool, a new car engine, etc. A design patent is due to the visual shape or design embodied in or applied to articles of manufacture.
