The author discusses the issue of co-authorship of scientific works. The adopted meaning of 'scientific works' is very broad, not limiting the matter to the sphere of copyright which is naturally brought to mind. Co-authorship in the discussed field is examined on three planes. The first one is copyright. The second one is intellectual property law, especially a problem whether an author of a scientific work can be treated as a co-inventor. The last, third plane, deals with the provisions of the civil code in connection with publicity rights which, among others, refer to scientific work. According to the author, not only scientific work is protected but also scientific co-work treated as a publicity right. The civil code can supplement the role of copyright and intellectual property law in this respect, protecting the interests of those authors of scientific works who are not protected by those latter acts. Discussing the issues, the author focuses on the analysis of the binding legislature in Poland. He also formulated conclusions de lege ferenda, calling for some changes in law.
