A consumer survey, as an instrument used to gather data on the beliefs and attitudes of consumers towards trademarks or products, is considered to have vital influence in trademark litigation. In recent years, courts have come to rely increasingly on the results of surveys conducted by one or both litigants in trademark lawsuits. The practical issue for trademark litigants is determining whether, when and how to develop survey evidence, given the cost, time, and other constraints. To shed light on this specific issue, we undertook a statistical analysis of trademark infringement cases in China. By examining 17 836 cases decided by China's courts over a 16-year period from 2001 through 2016, this article presents an empirical study assessing the statistical relationship between the presentation of survey evidence and case outcomes. The goal of our study is to help trademark litigants to determine the importance and value of presenting consumer surveys in trademark infringement case and make more informed decisions about their litigation strategies.
