Your "inverse pattern" needs to prevent a match at any single position
occupied by a match of the original pattern.
I tried with some examples:
A literal pattern:
/setf
->
/\%(setf\|s\@<=etf\|\%(se\)\@<=tf\|\%(set\)\@<=f\)\...@!.
Pattern with .* that for example matches "highlightin":
/hi.*in
->
/\%(hi.*in\|h\@<=i.*in\|\%(hi.*\)\@<=.*in\|\%(hi.*i\)\@<=n\)\...@!.
Pattern with or-branch:
/any\|match
->
/\%(any\|match\|a\@<=ny\|m\@<=atch\|\%(an\)\@<=y\|\%(ma\)\@<=tch\|\%(mat\)\@<=ch\|\%(matc\)\@<=h\)\...@!.
/\v%(any|match|a@<=ny|m@<=atch|%(an)@<=y|%(ma)@<=tch|%(mat)@<=ch|%(matc)@<=h)@!.
etc.
... very impractical. I'm not even sure if you can do it in general.
Just for highlighting, I'd do
:match Ignore /{pattern}/
