You are free to make use of the information in the spec - though you
might infringe their copyright if you published the same information
that is on the Microsoft and Adobe sites without their permission.
There is no patentable information in the specification - the part
that is proprietary are the particular implementations used by Adobe
(Cooltype) and Microsoft (Uniscribe) and you can't copy those. But
there have been several free and open source implementations of
OpenType layout around for almost 10 years - and newer ones too- which
is freely available and you can freely make use of under the
licensing terms of that code. Or you could write your own.

I'm sure people like RedHat, Debian, and Sun/Oracle (who use it in
OpenOffice) - have satisfied themselves that the open type rendering
they use is unencumbered.
