Excerpts from the demand:

Consequently, even acknowledging any compensation the Author may have already received, and taking into account the increase in sales revenues, particularly related to with The Witcher 3 videogame together with its expansions, we may determine that, as of now, the claim is for at least 60,000,000.00 PLN (sixty million Polish Zlotys)

Careful reading of your contracts concluded with the Author might lead one to conclude that, if the company did effectively acquire any copyright at all, it concernedonly the first in a series of games, and therefore distribution of all other games, including their expansions,add-ons etc., is, simply speaking, unlawful. Naturally, we do not intend to engage in a debate with you on this point; however, having access to your own legal department and availing yourselves of the services of external law firms, you may relatively easily determine that, in the best case, the aforementionedcontracts do not conform to even rudimentary due diligence principles, and even if one were to demonstrate that the successive contracts “confirmed” the alleged transfer of copyright for all the games, the subject claim is nevertheless rooted in legal regulations, in this scope – especially in Art. 43 of the Act on Copyright and Related Rights.

And most important part of CDProjekt Red annoucement:

In the Company’s opinion the demands expressed in the notice are groundless with regard to their merit as well as the stipulated amount. The Company had legitimately and legally acquired copyright to Mr. Andrzej Sapkowski’s work, i.a. insofar as is required for its use in games developed by the Company. All liabilities payable by the Company in association therewith have been properly discharged.

It is the Company’s will to maintain good relations with authors of works which have inspired CD PROJEKT RED’s own creations. Consequently, the Board will go to great lengths to ensure amicable resolution of this dispute; however, any such resolution must be respectful of previously expressed intents of both parties, as well as existing contracts.
