The article is devoted to the legal issues of the exercise of the intellectual property rights. The author distinguishes two possible cases of the exercise of these rights in accordance with the recent Czech law. One of them is granting consent to use some protected values. This situation is a circumstance precluding unlawfulness. The second case involves a licensing agreement conferring obligation between the parties. The author presents the legal grounds for the fact that in many cases, which are known from the contemporary knowledge and information society, it is only the consent which has the legal reason.
