“There are three kinds of lies: lies, damned lies, and statistics.”  ~British Prime Minister Benjamin Disraeli

Surveys are everywhere and poll results are available for every imaginable topic.  In the U.S.,   there were concerns about the admissibility of surveys for hearsay reasons but legislative amendment (Rule 702 of the 1975 Federal Rules of Evidence) eliminated  objections, making surveys a legally acceptable form of evidence. In fact, the submissions of survey evidence in trademark cases have become commonplace, and judges and juries afford great weight in these types of cases to survey results.

In “Trademark Surveys: A Litigator’s Guide,” authors James Berger and Mark Halligan provide a legal guidebook on developing and critiquing trademark surveys. In addition to describing the process and different types of surveys that may be employed, the authors offer strategic insight into how best to use these surveys to save time and money.

In trademark cases, a plaintiff alleging infringement and unfair competition must provide evidence of the infringement, including the likelihood of consumer confusion. Confusion is a mixed matter of law and fact and can be established using some guiding principles. These principles or factors are commonly known as the Sleekcraft factors. These are:

  1. Strength of the mark;
  2. Proximity of the goods;
  3. Similarity of the marks;
  4. Evidence of actual confusion;
  5. Marketing channels used;
  6. Degree of care used by the consumer when purchasing;
  7. Defendants intent in the selection of the mark; and
  8. Likelihood of product line expansion.

A survey for litigation is a market research survey that, when properly conducted, is intellectually and methodologically closer to a controlled scientific experiment than to most forms of traditional market research. Survey evidence is useful to measure the impact of a mark or competing marks in the marketplace. For a survey to be admissible and persuasive at trial, it must be done correctly.

Consumer surveys that provide evidence of confusion are common in trademark litigation, yet the frequency of their application does not mean the method is accepted without challenge. First, it should be noted that every survey actually consists of a sampling plan, a set of questions (the survey instrument), and a method of administering the questions. Each aspect, the sample, the instrument, and the implementation, must be designed according to scientific and accepted research practice.

Surveys for litigation are used in matters involving trademarks, trade dress, false advertising and unfair competition, and have numerous purposes. They can be used to determine the likelihood of confusion between marks, that a mark has acquired secondary meaning, or whether a word, color or shape has trademark or generic significance. Additionally, survey evidence may show that a mark is famous or that use of an infringing mark is causing dilution.

The challenges in designing surveys includes 1) locating the correct population; 2) determining the appropriate form of survey administration; 3) determining how to use technical language; 4) setting up the research to accurately reflect the market conditions; and 5) evaluating the appropriateness of  trademark survey questions.  Generally, the survey should be designed such that all potential sources of bias are minimized and the questions address the specific issue required for the litigation.

If you want to conduct trademark surveys — or defend against them — it’s a must-read!  You may also want to take a look at “Linguistic Battles in Trademark Disputes by Roger W. Shuy.
