Intellectual property - Legal monopoly or subjects of free competition

In this text the authors are trying to clarify in what extent the rights of intellectual property, as legal monopoly and deprivation of exploitation because of the foregoing, affect negatively on competition. Legal exclusivity in employing these rights protects the author, but also deadens competition which is opposite to purpose of anti-monopoly regulations' goal. Both in theory and jurisprudence as well, more and more prevails the idea that the exclusivity in exertion of these rights must give away the lead to realization of the competition rights in a certain market. Thereat, even though the reason of all legal perceptions (comprehensions) is the same in that regard, the criteria in executing this reason are after all different in comparatively-legal systems.
