1. Trevor Baylis, a British inventor, submitted a patent application in November 1992 for a windup radio for use in Africa in areas where there was no electricity supply and people were too poor to afford batteries. He was excited by the prospects for radio broadcasts as a means of disseminating health education in areas of Africa devastated by AIDS. After appearances on British and South African TV, Baylis attracted a number of entrepreneurs and companies interested in manufacturing and marketing his clockwork radio. However, Baylis was concerned by the fact that his patent provided only limited protection for his invention: most of the main componentsa clockwork generator and transistor radiowere longestablished technologies. What advice would you offer Baylis as to how he can best exploit his invention?
