               Who Cares About The 85 Percent?

Reconsidering Survey Evidence Of Online Confusion

                            In Trademark Cases

                                        Abstract
        There is an assumption in US trademark law that the protection of consumer interests-
     a traditional pillar of trademark law- is best achieved by enjoining a defendant's use
     of a mark that creates a likelihood of confusion (with the plaintiff's mark) for 15% or
     more (sometimes less) of relevant consumers. Courts often use survey evidence to
     determine the existence of a likelihood of confusion. This article argues that the in-
     terests of all consumers are relevant in that determination. This means that assessing
     the costs, if any, imposed on nonconfused consumers should also be part of the equa-
     tion. This can be accomplished in part by making better use of verbatim answers and
     by taking a deeper look into the information conveyed by the survey. Likelihood of
     confusion analyses should be both quantitative and qualitative.
