I wouldn't count on it -- if anything, they'll think, "hmm, we could be next, we'd better start getting patents of our own." Then once they have patents, someone in management will ask, "hey, we have these expensive patents, why don't we deploy them against the competition." That's especially true if some exec wants to get credit (and bonuses) for a license royalty stream or a damages award.
