I don't know much about Russian copyright law, but at least the idea of the German copyright law (Urheberrechtsgesetz) is very different from the US one. Here the central concept is the "Urheberschaft" (authorship; this implies that you have to be acknowledged as author) which cannot be sold, donated, refused etc. (as opposed to in the copyright law). The only thing that can be sold are the Nutzungsrechte (rights of use), which allow to redistribute the work and make money from it. Thus in Germany there exists for example no analogue to public domain work: Since Urheberschaft cannot be donated, one simply cannot put works under public domain, see for example https://www.sqlite.org/copyright.html https://www.sqlite.org/copyright.html
