Hi
I really do not know exactly the date where Microsoft stopped all OS/2 development.
According to history OS/2 was developed under an agreement called "
Joint Development Agreement Between IBM and Microsoft".
I'm not a lawyer to make an statement about the document and some annex are missing, but it states some things like:
DEFINITIONS:
"Code" shall mean Joint Code, MS Code or IBM Code, or any combination thereof, as generally defined below. "Source Code" ยท shall mean Code in source language form and "Object Code" shall mean Code in machine language form.
4.0 DISCLOSURE OF INFORMATION
For a period of ten (10) years from the date of receipt of Source Code from the other party, neither party shall disclose to any third party such Source Code of the other party unless such disclosure is made in accordance with terms aad conditions regarding coafideatiality substantially similar to those contained ia Addendum A to this Agreement, entitled "SAMPLE CONFIDEJlTIAL DISCLOSURE AGREEMENT".
According to the agreement Phase II documents are the ones generated on the agreement (the OS/2 components and products may be one of those).
There it is "3.2.1 With respect to Joint Code and Joint Documentation" It says that both parties (MS and IBM) are the owners of the product. But then there is "3.2.2 With respect to IBM Code and IBM Documentation:" and "3.2.3 With respect to MS Code and MS Documentation:" which says IBM owns his own generated products and MS owns its own generated products.
The issue is that I don't have the annex to know what components are Joint Code, MS Code or IBM Code.
15.0 TERM AND TERMINATION
(g) The .terms of the Section entitled "Disclosure of Information" shall survive the termination of a Phase II Document until ten (10) years have expired from the effective date of such Phase II.
It is possible that the copyrights are owned by Microsoft and IBM on the source code, but maybe the source code can be disclosed by now
