There isn't a ready-made command to do so, but you can easily script it:

  git for-each-ref --format='%(refname)' refs/heads |
  while read ref; do
	echo "$(git diff-tree -p "$ref" | git patch-id) $ref"
  done |
  grep $PATCH_ID_YOU_ARE_LOOKING_FOR

If you want to look further back than the tips, you can feed the branches to rev-list, and then patch-id each commit you find.

The more common way to use patch-ids is to look for commits that are in one branch but not another. For that, try the "--cherry-pick" and "--cherry-mark" options to "git log".
