It is clear that intellectual property, in its various forms, has a direct and significant impact on society, regardless whether the intellectual property has been legally protected or not. It impacts commerce by providing a general flux between the production of goods and services at a source and a “drain” point of consumption. Intellectual property is an integral part of trade regulations and treaties. Notably, a “free trade” zone is not quite so “free” when only the ones who possess the intellecual property rights are legally able to commercialize the products.
It affects economics of various societal groups in many ways.
It affects society directly by requiring education, in exchange for greater security (more advanced weapons, protection against natural disasters and pestilence), improved health (greater longevity and quality of life), increased food supply (adequate nourishment), enhanced mobility (means of transportation), etc.
When Germany and The Netherlands experimented brriefly with the abolishment of patents in the late 1860s (see The Economist of London which strongly supported this short-lived philosophical movement), they found that the need for progress in technological advancements was too powerful a pressure and could only be made to move forward by properly regulating the rights to individuals for their intellecual products.
It may even be said that in Europe, there is today an enhanced focus on regulating intellectual property. Note the new Pirate Party” that now appears to have a seat in the EU parliament representing Sweden, that was formed after the recent court case against the developers of Pirate Bay peer-to-peer software. Note that it appears that this court case did very little to stop intellectual property piracy on the Internet.
