Qualifications as a Testifying Expert

Jacob Jacoby has been providing testimony in U.S. District Courts since 1978 and has played a lead role in conducting more than 1,000 consumer, marketing and communication (trademarks, advertising, packaging, etc.) studies in support of litigation. Over that period, he has proffered testimony in U.S. District Courts in more than 150 litigated matters1. With relatively few exceptions, courts have admitted and given weight to his testimony.

At the invitation from the American Bar Association, Prof. Jacoby has finished authoring a treatise entitled Trademark Surveys scheduled to be published under the ABA imprimatur by the end of 2013.

The influence of Jacob Jacoby’s testimony, research and writings (especially those pertaining to issues of survey research in support of litigation) extend beyond individual cases. As examples:

Examination of J. Thomas McCarthy’s hornbook McCarthy on Trademarks and Unfair Competition, particularly the “Survey Evidence” section of Chapter 32, reveals that Jacoby is the most cited survey researcher in that treatise.

Two 1987 Second Circuit opinions2 cited his research as the basis for shifting the burden of proof in trademark disclaimer cases from plaintiff to defendant.

In 1995, at the invitation of the Federal Judicial Center, Jacoby presented a set of lectures on how to evaluate survey research to judges and magistrates attending the Federal Judicial Center’s workshops for District Court judges held in Atlanta and Seattle.

In 1994 and again in 1998, he was invited by the Federal Judicial Center to serve as a peer reviewer for the “Survey Reference Guide” appearing in the 1994 and 2000 editions of its Reference Manual on Scientific Evidence.

Jacob Jacoby has been an invited speaker on the subjects of litigation surveys and consumer confusion/deception before a wide variety of audiences, including:

  • The International Trademark Association
  • The International Bar Association
  • The Federal Trade Commission
  • The Food and Drug Administration3
