8. How and when does a patent begin making money?
A patent, maintenance thereof, and possible defense against patent infringements cost money. It is, however, an essential requirement for an invention to make a profit and for the inventor to receive a proportionate amount of the profits.
Revenue can be generated by issuing licenses or selling the patent. Contact is made with interested companies for this type of commercial exploitation; negotiations are conducted on the form of the license as well as its terms and length.
