Do you have products you wish to export to the United States, a film or book you want distributed there, or a website seeking US customers? Do you also use images or other identifications of famous people without consent in your product, film, book or website?
If you answered "Yes" to both questions you should seek legal advice on whether you need to obtain consent, permission or clearances before you export or publish in the US. This is because of the laws in the US known as "publicity rights". While ultimately specialist advice may be needed from a US attorney, this article is an introduction to publicity rights. It is illustrated by a New York court case involving the estate of Marilyn Monroe.
The court described the case as "a tortuous series of [legal procedural] events" ... over "Marilyn Monroe, perhaps the most famous American sex symbol of the twentieth century...". It ruled there are no Marilyn Monroe publicity rights.
