I believe that it was Hitachi that stole MVS/XA source code. I don't know the terms of the settlement.

REXX) Making PLX Internal to IBM may be to protect its Intellectual Property. I remember a vendor taking some IBM source,, renaming it and shipping it. When it went to court, they compared the vendor code with IBM code, and noticed that the code was similar, the developers had the same initials, and both "developers" had made the same spelling mistakes in the code. Wow - what an amazing coincidence! Remember if you go to court, you have to consider the cost of winning the case! Making PLX internal to IBM may be part of the cost of winning.
