NYCLA Opinion: In Certain Circumstances, 'Dissemblance' By Attorney-Supervised Investigators Is Permissible to Gather Evidence

Ethical prohibitions impact the common practice of almost every active trademark lawyer regarding his or her use of private investigators to collect information from third parties. However, the scope of permissible conduct is not always clearly defined. For instance, when a search report reveals one possible bar to your client's adoption of the mark, such as a nine-year-old federal registration by an individual who does not appear to have a Web site, can you or your investigator contact this person and devise some plausible explanation for the reason that you want to know if the mark is still in use? Or if you discover that a company appears to be infringing your client's trademark, can you send someone pretending to be a customer, but who asks all sorts of questions relevant to proving infringement that the ordinary consumer is highly unlikely to raise? Does it matter if the person you or your investigator makes contact with is a low-level sales clerk or the owner of the company?
