The other day a client sent me two pictures. One was of a someone else’s textile design, and the other was my client’s own rendering of it. The client said “We copied our design from their design. Can you tell us whether it’s infringing?” Rather than respond to the email, I called my client and reminded him about the rules of discovery: although any communications I have with my clients—including communications in which a client admits to having copied something—are protected by attorney-client privilege, mistakes can happen when even privileged documents are inadvertently produced in discovery in the event of a lawsuit. Also, if he inadvertently shares those communications with third parties, the attorney-client privilege goes out the window. So, saying incriminating things in emails (or texts or worst of all social media) can live forever in a way that’s inconvenient if not destructive.
