A plaintiff must establish three elements to hold someone liable for unlawful use of name or likeness:
1. Use of a Protected Attribute: The plaintiff must show that the defendant used an aspect of his or her identity that is protected by the law. This ordinarily means a plaintiff's name or likeness, but the law protects certain other personal attributes as well.
2. For an Exploitative Purpose: The plaintiff must show that the defendant used his name, likeness, or other personal attributes for commercial or other exploitative purposes. Use of someone's name or likeness for news reporting and other expressive purposes is not exploitative, so long as there is a reasonable relationship between the use of the plaintiff's identity and a matter of legitimate public interest.
3. No Consent: The plaintiff must establish that he or she did not give permission for the offending use.
"Likeness" refers to a visual image of the plaintiff, whether in a photograph, drawing, caricature, or other visual presentation. The visual image need not precisely reproduce the plaintiff's appearance, or even show his or her face, so long as it is enough to evoke the plaintiff's identity in the eyes of the public.
