Does anybody know how the chaum patents (I think they claimed somewhere that
they had applied for some) affect Brands system?

Chaum has several patents relating to digital cash, the core one being a
patent on the blind signature methods commonly in use. When I last heard
an update on the Chaum/Brand saga it was that Brand believed his system
avoided Chaum's patents while Chaum "had not yet been convinced that this
was so, but it was a possibility."
