Hilde purchased all of the rights to a patent on a new garden tool developed by a friend of hers who is an amateur inventor. The inventor obtained the patent rights, set up a manufacturing company to produce and sell the garden tool, and produced substantial quantities of the tool, but he then became discouraged when no large garden company would agree to distribute the tool for him. Hilde purchased the patent rights (but not the manufacturing company) for $120,000 on October 24, 2016. Hilde had never engaged in such a transaction before, but she is a salesperson in the garden industry and thought she could succeed where her friend had failed. On June 27, 2017, she sold all patent rights to Garden Tool Company for $1,233,000. Garden Tool will manufacture the tool in its own factory and sell it to its customers.What is the nature of Hilde’s gain from this transaction?
