You have bred a new cultivar of bread wheat that you wish to market in the U.S. and Europe. You wish to prevent potential competitors from breeding with your new cultivar because it has unique and highly desirable quality traits, which you wish to remain proprietary. Your plan is to market the wheat cultivar directly to large manufacturers of bread, and those companies will hire growers to produce the grain for the bread manufacturers' use. List and describe four strategies for protecting plant IP, and describe the relative advantages and disadvantages of each. How would you protect your intellectual property in the U.S. and in Europe (i.e. which method or combinations of methods would you choose) and why?
