Patching problem

Usually patch is done by:
  diff -Naur file1 file2 > patch.1
And to patch file2:
  patch < patch.1

Now let's assume that I want to patch file2 with the differences from file1. However all the initial differences of file2 I want to keep.
In other words I want to apply only '+' changes in patch.1 but not to apply '-'.

Is it possible ? And if yes, how can I do this...

Can you please be more specific. I didn't find any patching issue on this forum.
What are you trying to do exactly?

Your commands would take the differences between file1 and file2, then
apply them to file1.

If you're trying to do a 3-way merge changes from one set of files into a third
then the command you should be using is merge...

Thanks Mysidia,
I wanted something else, but with merge I can achieve same result.
