The practical application of the results of intellectual activity is the driving force of economic and social development. Their intangible nature created serious difficulties in extending them to the principles of private property inherent in the market economy. In order to overcome them, throughout the nineteenth century, with the expansion of the role of knowledge and information, a number of laws on the legal protection of the most important intellectual creations (inventions, trademarks, literary works, etc.) most European countries. Over time, intellectual creatives become extremely valuable patrimonial objects, important sources of competitive advantages and additional profits, objects of commercial exchanges, and in the twentieth century an important subject of corporate management too.
