Brian Brunner is an entrepreneur who has invented several devices that are used in the telecommunications industry. He has patented the devices and manufacturers them in a job shop in Oklahoma City. Brian sells the devices directly to AT&T and Verizon. Last week, Brian got a certified letter in the mail from Nokia, indicating that firm’s interest in licensing the technology that is represented in one of his devices. Brian doesn’t know anything about licensing and has turned to you for help. What would you tell Brian about licensing, and how would you suggest that he respond to Nokia’s letter?
