Cellar Ltd is in the business of bottling wine, particularly for small wineries that cannot afford sophisticated technical equipment and prefer to concentrate on the growing of the grapes. The white wine and champagne bottles used by Cellar Ltd have a built-in insulation device that keeps the contents of the bottle cold even when held in the hand.

In January 2023, Solar-Blue, a company experimenting with energy sources useful in combating climate change, produced a device which, when attached to the outside of a container, could display the actual temperature of the liquid inside. The temperature was displayed by the highlighting of certain colours on the device. How this device could exactly be used with wine bottles had yet to be specifically determined. However, Cellar Ltd believed that its employees had the skills that would enable the company to determine the feasibility of such a project. They predicted that the additional costs of incorporating the device would be $40,000 with additional revenue of $170,000. They were quite certain about the incorporation outcome.

Cellar Ltd paid $100 000 for the exclusive rights to use the device in conjunction with bottles. Several days after they bought the device, a major competitor who missed the chance of buying the device directly from Solar-Blue, approached Cellar Ltd to discuss the intention of purchase at the price of $110,000.

Cellar Ltd could cease development of the device in relation to its applicability to use with bottles. They could luck up the device reducing the risk that competitors could achieve a significant market edge and so substantial increase market share. By taking this defensive competitive strategy, they predicted a net benefit of $140,000 from future weaken competition. They were quite confidence about their estimates.

In this case, what is the best and highest use of the device?
