The answer seems to be that Soderblom does indeed want royalties on FDDI
technology.  From a knowledgeable source:
> Soderblom's patent claims fundamental concepts of token ring networks,
> and he asserts that IEEE 802.5 and FDDI incorporate aspects of his
> patent.  He wants royalties on any device incorporating these token
> rings.  The royalties are not prepaid by the chip vendors (TI for
> 802.5, AMD for FDDI).
