Due to the fact that the American system of stimulating scientists in America is well-developed and structured, the increase in the number of patents and licenses in American universities has a steady growth trend.
For example, in the period from 1980 to 2002, their number increased approximately 14 times, amounting to 3673. In general, the USA accounts for 25% of all patents registered in the world.
It can be emphasized that income from patents and licenses is a way to replenish the budgets of universities in the USA.
If a particular discovery receives a patent that has commercial value, a significant part of the income from it is taken by the university where the scientist works. A common method is when the inventor receives a certain share of the remuneration (royalty) due to the university as the owner of the patent. Thus, there is a mutual stimulation of both universities and inventors.
In general, the effect of licensing activities of universities in the USA is quite high and is a serious argument in favor of the advisability of borrowing experience in this area.
