the second version object server. The examiner finds that the IBM
Model Guide teaches allowing changes to SOM objects while
maintaining compatibility and verifying an object’s version
information for compatibility checking. The examiner asserts that
the artisan would have been motivated to apply the teachings of the
IBM Model Guide to the IBM Design Guide because it would avoid
recompilation of client programs when certain compatible changes
occur. The examiner also asserts that the step of verifying before
the step of generating would have been obvious to the artisan
[answer, pages 4-5]. With respect to independent claim 24, the
examiner additionally asserts that it would have been obvious to
the artisan to include a user selectable compiler option to expose
the functionality of the IBM Design Guide as modified by the IBM
Model Guide [id., page 5].
With respect to independent claim 1, appellants argue that
the IBM Model Guide operates only to verify if an already compiled
object server is a compatible version. Appellants argue that there
is no suggestion within the IBM Model Guide that it can be used by
a computer at the time of compiling a program to verify whether
modified and as yet uncompiled source code of the object server can
be compiled so as to yield a still compatible object server.
Appellants also argue that the proposed combination is impossible
