Intellectual Property Survey – Make Sure You Know the Rules

Intellectual Property Surveys

Make sure you know the rules

The following factors courts often consider when determining the admissibility of a Lanham Act survey, to guide its surveys and reports. Specifically, whether the:

  1. population was properly chosen and defined
  2. sample chosen was representative of that population
  3. data gathered were accurately reported
  4. data were analyzed in accordance with accepted statistical principles
  5. questions asked were clear and not leading
  6. survey was conducted by qualified persons following proper interview procedures
  7. process was conducted to ensure objectivity

Relevant Universe

Ms. Harper knows that if the right audience isn't surveyed the entire study can be disqualified. That's why she examines and measures the responses of purchasers and potential purchasers of the products or services at issue. She takes great care to ensure that the universe neither excludes potential purchasers (under-inclusive) nor is overbroad (over-inclusive).


Most of the time it would be impossible, or infeasible, to test all prospective purchasers in the relevant universe. We employ sampling procedures that statistically project results to the entire universe. Courts demand that such procedures be in accord with accepted, unbiased statistical principles.

Collection Method

Ms. Harper relies on online studies for its surveys. Now common due to household penetration rates, large panels, and cost, Harper Litigation Consulting and Research uses the leading, premier online platforms and sample companies.


With 30+ years of research experience, Ms. Harper knows how to accurately collect, analyze and report data in accordance with accepted statistical procedures. Among the many considerations, we deploy the right survey types, ensure not to use leading questions, and take great care to code and accurately represent the findings.


Ms. Harper understands that "noise" occurs within surveys. In most cases, courts require that a survey include a control in order to address possible noise among consumers. Using a control group or question, we can test directly the influence of the stimulus.
