How sure are we IBM is only pursuing a patent in the US?

IDEA is patented in most of Europe, where non-US is located.

Probably, or use a free IDEA implementation (e.g. from the Pike crypto
toolkit, or from mcrypt).

I've not seen a concensus opinion about patent issues in Europe affecting
non-US. Personally, I think that patent-encumbered algorithms should not be
considered free, except where the patent is licensed in a liberal way
(allowing free use in free software).

CAST-128 was specifically not patented to allow it to become an IETF
standard. I hope that if it's patented, its licensing condititions will be
favourable.
