How have you dealt with the patent claims which Microsoft has
asserted[1] on the exFAT file system design?

[1] https://www.microsoft.com/en-us/legal/intellectualproperty/mtl/exfat-licensing.aspx

I am not making any claims about the validity of Microsoft's patent
assertions on exFAT, one way or another.  But it might be a good idea
for some laywers from the Linux Foundation to render some legal advice
to their employees (namely Greg K-H and Linus Torvalds) regarding the
advisability of taking exFAT into the official Linux tree.

Personally, if Microsoft is going to be unfriendly about not wanting
others to use their file system technology by making patent claims,
why should we reward them by making their file system better by
improvings its interoperability?  (My personal opinion only.)

Cheers,
