Consumer Protection & False Advertising Disputes

Consumer protection-related litigation appears to be on the rise, in a broad range of areas that include allegations of product liability, consumer fraud, false advertising and deception, privacy and data breaches, and violations of the False Claims Act.

This topic is also receiving increasing attention from enforcement authorities at the federal and state level. For example, the Federal Trade Commission (FTC) identified protecting consumers from unfair and deceptive practices as among its top goals in its strategic plan for 2018–2022. Similarly, Maryland amended its related statute to expand the scope of consumer protections and increase the penalty for violations of consumer protection laws.

Below is a list of representative engagements for our Consumer Protection & False Advertising Disputes practice.

Class certification in case involving defective vehicles

On behalf of a leading U.S. vehicle manufacturer, prepared testimony debunking the opposing experts’ analyses, which purported to assess damages that class members had incurred by purchasing the manufacturer’s allegedly defective vehicles. Demonstrated that, while plaintiffs’ experts purported to compute the impact of the false claims on the vehicles’ market price, the opposing expert’s analyses could—at best—only be used to determine the impact of the alleged defect on consumer willingness-to-pay (i.e., demand). Further demonstrated that the conjoint analysis offered by the plaintiffs’ survey expert was improperly constructed, making its estimates of consumer willingness-to-pay unreliable. Our client received favorable ruling in a decision that drew heavily from this work.

Analysis of damages arising from misleading claims

On behalf of a major Canadian automobile manufacturer faced with a class action lawsuit regarding misleading fuel efficiency reporting, Brattle filed an affidavit scrutinizing the plaintiff’s expert’s demonstration of likely damages to the proposed class of auto buyers. The critique demonstrated that the class’s expert made several assumptions at odds with economic theory regarding buyer behavior.

Class certification in alleged false advertising case

Our client, a producer of branded nutritional supplements, had been accused of collecting a market price premium on its products due to alleged false claims appearing on the product label. Brattle’s expert testified that the plaintiff’s expert had failed to describe a workable approach for determining the damages associated with this price premium on a class-wide basis. In particular, Brattle’s expert explained that the plaintiff’s proposed use of a conjoint analysis to assess the price premium was unworkable because conjoint survey data only take into account demand-side factors, whereas a price premium would be the product of both supply and demand factors. Brattle’s expert also explained that the plaintiff’s proposed use of a hedonic analysis was unworkable because the available data would not allow for a separate estimation of the price premium.

Lanham Act claims against a producer of food additives

Brattle economists were retained by a trade association representing a common food additive producer that had alleged that the trade association for a competing additive had misled consumers regarding its negative health effects. We advised the client’s academic damages expert and provided a rebuttal report and testimony regarding the opposing damages expert’s calculations. We relied on several econometric techniques to demonstrate the unreliable nature of the opposing expert’s approach.

Likelihood of confusion in the fashion industry and associated damages

We were retained by a British manufacturer of distinctive footwear claiming that a U.S. shoe company had infringed on the trademark stitching on some of its shoe products. A Brattle economist estimated damages based in part on surveys conducted at shopping malls. Using the survey data, we were able to evaluate the extent to which consumers were confused by the allegedly infringing shoes, measure lost sales, and establish the value of the trademarked stitching, a distinguishing feature of the British company’s shoes. The case settled on favorable terms for our client.

Alleged disparagement and false advertising in pharmaceuticals

Brattle worked for a large pharmaceutical manufacturer that alleged disparagement and false advertising by a competing manufacturer of an over-the-counter pain reliever in its communications with physicians. Our team analyzed survey data on consumer and physician choices; applied economic theory to assess the effect of misinformation on new product sales; and created a damages model to project the likely trend in sales of the plaintiff’s drug but for the alleged violations and to quantify the plaintiff’s losses.

False Claims Act (FCA) cases

In FCA matters, Brattle plays several complementary roles: forensic analysts, to identify and trace patterns in activity or financial metrics; big data analysts, to extract and summarize the relevant information from unstructured information sources; and financial and economic experts, to determine the effects of alleged misconduct and provide expert testimony. We have been involved in numerous FCA cases, from the investigation stage through litigation. We work extensively with proprietary, government, and publicly available datasets, and with economic, actuarial, and industry experts to cover the full range of issues in a given case.

Assessment of damages arising from a data breach

Working on behalf of plaintiffs in a matter related to a high-profile data breach, a Brattle team prepared reports explaining how to quantify the damage inflicted on individuals whose personal data was stolen. Our analyses in this matter included a novel approach that explained how data on the dark web sale of personal information could be used to objectively measure consumer losses due to the breach.

Allegations of pyramid scheme business models

Brattle has extensive experience analyzing the multilevel marketing (MLM) compensation models of nutrition, supplement, cosmetics, and other direct sales companies. Our team has been involved in many matters that have required analyses of customer-level data to assess whether that company’s compensation model has characteristics of a pyramid scheme – as opposed to a legitimate MLM model. Brattle has provided consulting services to companies conducting internal investigations of their MLM compensation models, as well as support to academics who have presented their findings to the FTC and state attorneys’ general offices.
