Pac-Man® Defense:
The target can defend itself by making a counteroffer to acquire the hostile bidder. This technique is rarely used because, in most cases, it means that a smaller company (the target) is making a bid for a larger entity. Additionally, once a target uses a Pac-Man® defense, it forgoes the ability to use a number of other defensive strategies. For instance, after making a counteroffer, a target cannot very well take the acquirer to court claiming an antitrust violation.
