When do I need a patent?
U.S. patent laws were enacted by Congress under its Constitutional grant of authority to protect the discoveries of inventors. In order to be patented an invention must be novel, useful, and not of an obvious nature. Patents are issued for four general types of inventions/discoveries: machines, human made products, compositions of matter, and processing methods.
Patents grant an inventor the right to exclude others from producing or using the inventor's discovery or invention for a limited period of time. In order to be patented an invention must be novel, useful, and not of an obvious nature. There are three types of patents: a) "utility patent" which includes a process, a machine (mechanism with moving parts), manufactured products, and compounds or mixtures (such as chemical formulas); b) "design patent" which is a new, original and ornamental design for a manufactured article; and c) "plant patent" which is a new variety of a cultivated asexually reproduced plant.
