Is it possible to Support exFat filesystem on SD cards?

Hi. We are wanting to support exFat filesystem on SD cards for our custom board that has a snapdragon 820 chip. It looks easy enough to add by installing exfat-fuse and exfat-utils. What I don’t know is if this is allowed per Microsoft patent described on this wikipedia page: The “Other Implementations” section is hard to interpret. Is it allowed or not on our custom boards that we would be selling to our customers?
Thanks for any information,

I don’t think we can help much with this, it’s a question for your lawyers together with Microsoft and/or OIN.
