There is no significant slowing down of the spread of information in the long run, since intellectual property generally only lasts for a short time, meaning owners have an incentive to make the most of it while they can. Besides, any small slowing down of the spread of ideas and innovations is a small price to pay for the recognition of a person's fundamental right to the product of his effort. Furthermore, licensing arrangements are becoming more and more refined to allow for the quick transfer of rights in order to meet societal demands for products. Licensing law has also begun to extend to products that producers may not wish to produce, such as medication for sick Africans, and is helping to force firms that refuse to act upon their patents to license the right to those that will.
