The influence and basis on, of MS-DOS and CP/M is undenied.

In fact, the clear copyright issue was apparently why IBM chose to ALSO 
sell CP/M-86.  However, there are disagreements about whether the pricing 
choice was an IBM effort to sabotage the CP/M-86 sales, or a serious error 
by DRI.  (I believe the latter)

But, Gary (and Xerox Parc) was not litigious.
