The article is of a scientific and research nature and presents the problem of a possible cancellation of joint ownership of the copyright in non-litigious proceedings during litigation between the same parties concerning the infringement of copyright to an audiovisual work. In connection with the doctrinal dispute regarding the cancellation of commonality of copyright, the authors present arguments in favour for such a possibility in light of the provisions of both copyright law and civil law, and they discuss the procedural provisions related to such cancellation. An important aspect of the problem addressed in this paper is also the impact of the proceedings for the cancellation of commonality of copyright on the ongoing litigation proceedings between the same parties concerning the infringement of the author’s economic rights. As a result of the analysis of the current legal status, taking into account the events of a past court case, the authors present conclusions of the law as it stands with regard to the need for changes in civil procedure – the proceedings in intellectual property cases. It should be emphasized that the addressed research problem concerning the mutual relation between the substantive law provisions and the civil procedure in the scope of cancellation of commonality of the author’s economic rights has not hitherto been described by legal scholars and commentators.
