Atlas has probably bust up a couple of Pennies before this. It's no issue. I wonder if they even consider her a legal person (probably not). We heard from Penny that she is the first of her kind. As long as Ironwood does not later disfute this, we can take it for granted that she is the only one of her kind right now. (And for the fact that Ironwood talked during the maiden scene that they had recently started experimenting with putting aura into other units, not leaving that much time for multiple Pennies.)

Ironwood does say "the girl" when talking to Ozpin on the phone, so it gives some hope that he does consider her a person at least.
