Identifying the Likelihood of Confusion
A likelihood of confusion survey from Keegan & Donato Consulting is a valuable litigation tool because it addresses the issue of consumer confusion from a scientific perspective, providing empirical data regarding the extent to which consumers believe that the brands at issue come from the same source or are somehow related.
By asking relevant consumers to respond to certain stimuli and recording their answers, it is possible to measure their attitudes and behaviors and understand how they perceive a contested mark. This understanding of how consumers view the relationship between brands forms the basis of a likelihood of confusion analysis.
Our Survey Design Best Practices
Some of the industry best practices that Keegan & Donato Consulting builds into the firm’s survey designs include:
- Appropriate universe selection and sampling frame;
- Inclusion of representative, qualified respondents;
- Use of procedures to minimize potential biases in data collection;
- Usage of objective, non-leading questions;
- Using methods to reduce guessing among respondents; and
- Complete analysis and reporting of survey data.
We employ classic survey designs and will develop innovative custom survey designs to meet the needs of each case. Our industry-leading online survey software platform facilitates the programming and execution of advanced survey designs, including complex skip logic, advanced rotation, and randomization of questions, answer options, and stimuli.
Value of a Methodologically Sound Survey
In Rolex Watch USA, Inc. v. Michel Co., 179 F.3d 704 (9th Cir. 1999), Rolex sued Michel Co., a watchmaker, for trademark infringement, asserting that Michel reconditioned used Rolex watches with unauthorized, generic replacement parts but maintained the original Rolex marks on altered “Rolex” parts without adequate disclosures that the modified watches contain non-Rolex parts, which was inadequate for preventing consumer confusion.
The court relied heavily on a likelihood of confusion survey conducted by Rolex to establish whether or not consumers were confused between the two trademarks. The survey showed that a significant percentage of consumers believed that Rolex made the Michel watches. The court found in favor of Rolex and awarded damages to the company.
