Quizplus · Accepted Answer

A design patent gives the owner exclusive rights to use the design for fourteen years. The other options are incorrect. Patent law is enacted by Congress under the power given by Article I, not V, of the Constitution. A utility patent gives an inventor exclusive rights to make, use, or sell an invention for 20 years, not 25. Processes and machines can both be patented. A composition of matter may be patentable if it is man-made or significantly different from what occurs in nature.
