//Don't patents apply whether you reverse engineer it or not, depending on what the patent owner says?//
Yes they do.
The MS "IP" in question is not, however, patented. They are trade secrets.
In order to have a valid patent, MS must fully publish exactly how the format or protocol works. If they do that, they can get patent protection for 20 years on that exact method.
Microsoft have not published anywhere exactly how their NTFS filesystem works. It is a trade secret.
Therefore, MS have no patent on NTFS.
Similar story for the networking protocol that Samba reverse-engineers.
