The Witcher Author Demands Additional Royalties

A "regulatory announcement" from CD PROJEKT reports the receipt of a demand for payment from Andrzej Sapkowski, the Polish fantasy writer who created the series of The Witcher books that are the basis for CD Projekt RED's The Witcher RPG games (thanks DSOGaming). The letter indicates that an aspect of copyright law entitles the author to additional compensation, saying his current deal falls below an established minimum. They say this means the publisher owes Sapkowski at least sixty million Polish Zlotys, which is over $16 million USD by current exchange rates. For their part, CD PROJEKT does not embrace this alternate minimum concept, which goes unaddressed as they claim they are current with their obligations, though they add they are open to trying to work this out amicably:
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.
