No, in this case, they should be careful. Although scientific results are not protected, refining the material, i.e. the manner in which the lecturer transmits knowledge in a lecture, can definitely fall under copyright protection when the work character is fulfilled in the process. If the lecture notes are then developed into a script in such a way that they adopt the structure and content of the lecture, such a script can therefore be seen as a derivative work. The lecturer’s consent is required to produce the script and to use it (publication on the Internet).
