"The payment made by a manufacturer to a patentee for the privilege of using the patent process, is usually termed, in commercial language, a rent; and under the same head must be ranked all extraordinary qualities of body and mind"

Nassau William Senior is suggesting that the payment made by a manufacturer to a patentee for the advantage of utilizing the patent process must be considered a kind of lease. This rent is not just restricted to the payment made for the patent process, but also includes any extraordinary qualities of mind and body that the patentee might possess. Elder is indicating that these qualities should be taken into consideration when identifying the quantity of rent that is due. He is also suggesting that the payment must be considered a form of rent, rather than a one-time charge, as it is a payment for the privilege of using the patent process. This quote highlights the value of acknowledging the worth of the patentee's qualities, and the need to make sure that they are effectively made up for their work. It likewise functions as a reminder that the patent procedure is a valuable property, and that those who utilize it ought to want to pay a reasonable cost for the benefit.
