Indeed it's hard to know what parts of the huge USPTO database might
be relevant - it's not even possible to narrow it down to just patents
which have been filed by MS, as MS might own rights on patents or
patent applications which have been filed by others.  Many patent
holders would sell out to MS if offered enough cash.

MS has publicly spoken about "many patents".  We know only of a single
patent application.

There is no problem with these things because they're specified
in the ECMA standards, and MS has promised royalty-free licensing
for any and all patents that may be necessary to implement what is
in those standards.

The standards are freely available:

It would be helpful if someone could write a useful summary of what
is in there, and what are the important things which are missing.
