On November 4, 2011, during the seminar at the 15th Book Fair in Cracow, our lawyers – Mr. Piotr Suski and Mr. Marcin Mioduszewski – delivered a lecture entitled “Co-authorship of the works and publishing agreement. Legal aspects of the joint authorship copyright in market trade”. In their speech, our lawyers presented legal issues concerning works of joint authorship as a subject of copyright agreements.
