Performance Indicator is a start-up that holds patents on the use of color-change technology to indicate when golf balls have been damaged by exposure to water. Because golfers put two to five used golf balls into play for every one new ball they buy, the used golf ball market cuts severely into the sales of manufacturers. Performance Indicator's technology would dramatically curtail the availability of used balls, doubling or tripling the size of the market for new golf balls. At the time of the case, the founders have been pursuing this idea full time for five years, but have yet to convince any manufacturers to license their technology.
