More important, the patent is about "reduced keyboard disambiguating".
If the keyboard isn't "reduced", i.e. it has all the keys, then
that patent doesn't seem to apply.

The illume keyboard aren't missing any keys for example. It only uses a 
dictionary because users sometimes miss. There is no ambiguity at all to 
resolve, only error correction for fat-fingered typing. (T9 does not
try to resolve wrong-key misses) Disambiguating and error correction
is not the same.

Oh, and they mention "keyboards". Many phones has keyboards with about
12 keys.  The neo has a touchscreen instead, its two keys are not used
for text input. :-)
