8. How and when does a patent make money?
A patent, maintenance thereof, and possible defense against patent infringers cost money. It is, however, an essential requirement for an invention to make a profit and for the profit to be received by the inventor proportionately.
Income can be earned through the award of a license or sale of the patent. Contact is made with interested companies for this type of exploitation; negotiations are conducted on the form and the terms of license award and term of the license.
