"From Don Reba ( GSC Forums Moderator ):
Sergey Galyonkin got in touch with Grigorovich and found that:
1. He did not negotiate with bitComposer about giving them the rights to the trade mark S.T.A.L.K.E.R. and still keeps them for both USA and Europe.
2. bitComposer distributed Call of Pripyat and still owes GSC 8 months' royalties. "
