Question: James Cornheiser is six feet, nine inches tall and has been frustrated by the height of the chairs he has sat in his entire life. Since there are many tall people just like him, James decides to start a chair company that only makes chairs that are three inches higher than the typical chair. James builds his first set of prototypes and confirms that taller people find them more comfortable that standard chairs through a series of focus groups. James decides that he needs to protect his business idea, so he applies for a patent for his chair design. Is his patent application likely to be granted? a. Yes, because his chair design is new, useful and nonobvious. b. No, because his new chair design is merely an abstract idea. c. No, because his new chair design contains obvious changes to existing chair designs. d. No, because his new chair design is not useful.
