Worse yet, I find it amazing MSDOS was legal at all. It was a direct source code rip off of CP/M (MSDOS at the time was called Quick and Dirty OS). Only more limited and handicapped than CP/M was at the time.
Without MSDOS the industry could have looked a lot different than it is today.
However I am not fond of US patent laws (at least regarding the obvious, old and trivial), but copyright is of course a serious issue. US patents are also an issue regarding overseas R&D, what if every tiny little country in the world would introduce this system...

Maybe because IBM paid Microsoft to develop DRDOS for them and as a result they let MS produce their own version (MSDOS) which they opened up to all PC compatible machines. This blew the hardware market wide open and spawned the modern era of computing where multiple OS's are available for standardised PC hardware specifications (as I'm guessing you're alluding to). It's a benefit to the PC market pre windows that many Microsoft detractors don't consider. Once upon a time MS were the little guy who made the PC market cheaper for everyone.
I suspect the appeal will be successful, largely due to the fact the patent sounds "dodgy", for want of a better word.
*EDIT* I realise some of you guys covered this with later comments, sorry.
