Macrotech, Inc., develops an innovative computer chip and obtains a patent on it. The firm markets the chip under the trade- marked brand name “Flash.” Macrotech wants to sell the chip to Nitron, Ltd., in Pacifica, a foreign country. Macrotech is concerned, however, that after an initial purchase, Nitron will duplicate the chip, pirate it, and sell the pirated version to computer manufacturers in Pacifica. To avoid this possibility, Macrotech could establish its own manufacturing facility in Pacifica, but it does not want to do this. How can Macrotech, without establishing a manufacturing facility in Pacifica, protect Flash from being pirated by Nitron?
