When Vibram, the “FiveFinger” shoe company, was hauled into federal court in Boston in March, it became the latest prominent business swept up in the growing wave of consumer class actions based on false advertising claims.

That wave does not appear to have reached its crest, and with recent revisions to the “green” labeling guidelines, it may be far from its peak. Ultimately, no matter what products or services your company sells, advertising content can leave you awash in class-action lawyers — and more important, lead to tens of millions of dollars in exposure to damages for false or misleading advertising claims.
