Large companies are not endangered by patent lawsuits, not even from trolls. They have enough power to fight most suits and even when they lose it's not a big sting. Patent portfolios allow the giants to consolidate their position and defend against competition from smaller companies. Economies of scale in terms of lawyers is what small companies don't have and giants aren't shy about threatening smaller players who may pose a threat (although they usually just buy them out).
