 In the common case, one application causes the input focus to be moved to 
another application by doing nothing, as it's usually the user who decides 
which application will be active.

 So, if this is the common case, you already know the answer. If it's not, 
then please describe it, as there may be different solutions depending on 
what exactly you want to do.

 This seems to be a bug in focus stealing prevention, actually.
