Since so many users here are asking about the patents in question and the the exact claims as voiced by Microsoft, let me just post this information. Maybe other users should do their research and post links rather than specualte and ask questions that can be answered by simply looking at the patents.

Microsoft: FAT File System Technology and Patent License
U.S. Patent #5,579,517
U.S. Patent #5,745,902
U.S. Patent #5,758,352
U.S. Patent #6,286,013

The first of those patents was granted November 26, 1996, years after UMSDOS was implemented in Linux.

And don't forget the ISO9660 extensions for Unix (RockRidge) which add long filenames, ownership, permissions, devices, and symbolic links. Without that ISO9660 only supports uppercase filenames under 30 characters (and Windows actually restricts it to 8.3).

DOS restricts it to 8.3 (by obvious reason). Windows with 32bit driver (most Windows systems today) are just fine.

Ah, but Microsoft has its own ISO9660 extensions (they had to reinvent
the wheel) called Joliet and something else which I can't remember at
the moment :)

At least NT4.0 had problems with 30 character filenames on a CD I burned
about 4 years ago...

The important date for prior art, as I understand it (IANAL), is the patent application date, not the date it's granted.
