Recommended Reading: "The Role of Consumer Uncertainty in Trademark Law: An Experimental and Theoretical Investigation"

Barton Beebe, Roy Germano, Christopher Jon Sprigman, and Joel H. Steckel, scholars at New York University (the first three at the law school), have published an important article on the topic of trademark survey evidence: "The Role of Consumer Uncertainty in Trademark Law: An Experimental and Theoretical Investigation". For those of you contemplating the commissioning of a survey (and who isn't?), this is a must read. [download here].


Nearly every important issue in trademark litigation turns on the question of what consumers in the marketplace subjectively believe to be true. To address this question, litigants frequently present consumer survey evidence, which can play a decisive role in driving the outcomes of disputes. But trademark survey evidence has proven to be highly controversial, not least because it is notoriously prone to expert manipulation. In this Article, we identify and present empirical evidence of a related, but more fundamental problem with trademark survey evidence: while all the leading survey formats in trademark law test for whether consumers hold a particular belief, they do not test for the strength or the varying degrees of certainty with which consumers hold that belief. In short, by treating the question of consumer beliefs as essentially binary, the formats do not test for belief strength. Yet as the social science literature has long recognized, the strength with which consumers hold particular beliefs shapes their behavior in the marketplace, and thus it should also shape, we believe, how trademark disputes play out in the courtroom. Through a series of experiments using the three leading trademark survey formats (the so-called Teflon, Eveready, and Squirt formats), we show the remarkable degree to which these formats as conventionally designed overlook—or suppress—crucial information about consumer uncertainty. We further demonstrate how a low-cost, easily-administered, and relatively simple modification in these formats can reveal that information. We discuss both the practical and theoretical implications of our findings. As a practical matter, trademark survey evidence that shows only weakly-held beliefs (or that does not even test for belief strength) should not, without more, satisfy a litigant’s burden of persuasion on the issue addressed by the survey. Furthermore, in line with courts’ growing efforts in intellectual property cases to tailor injunctive relief, survey evidence showing only weakly-held mistaken beliefs may provide courts with the opportunity to fashion more limited forms of relief short of an outright injunction. As a theoretical matter, we explain how trademark survey formats that reveal the true extent of consumer uncertainty in the marketplace may finally force trademark law and policy to confront normative questions it has long left unanswered going to exactly what kind of harm trademark law is meant to forestall.
