patent with a 15-year remaining legal life was purchased for $270,000. The patent will be commercially exploitable for another nine years. b. A patent was acquired on a device designed by a production worker. Although the cost of the patent to date consisted of $42,300 in legal fees for handling the patent application, the patent should be commercially valuable during its entire remaining legal life of 18 years and is currently worth $378,000. c. A franchise granting exclusive distribution rights for a new solar water heater within a three-state area for four years was obtained at a cost of $63,000. Satisfactory sales performance over the four years permits renewal of the franchise for another four years (at an additional cost determined at renewal)
