The issue of intellectual property especially copyright becomes more important in the field of information technologies. An unauthorized use of author’s works results in damage especially for authors of computer programmes and database generators. The topic of the presentation is the clarification of categorization of intellectual property rights with focus on the detailed specification of copyright, its sources and possibilities of protection. Since the computer program is also an author’s work, its author is a owner of personal and property rights to it. One of the objectives of the lecture shall be clarification of those rights including the issue of rights to employee work. Another group of rights which shall also be the topic of the presentation is the issue of author contracts, i.e. contracts on work creation and license contract and the most frequent problems related to the creation and consideration of those contracts. At the end we shall introduce the web site www.itpravo.sk.
