The Stay hitmaker, real name Robyn Rihanna Fenty, applied to register her first name in June, 2014 with the view to "providing on-line non-downloadable general feature magazines".

Representatives for comic book publisher DC submitted a Notice of Opposition at the U.S. Patent and Trademark Office on 11 May (15), arguing that her application is too similar to the name of Batman's sidekick Robin, which has a variety of trademarks, some of which date back to the 1980s.

In the legal document, they claim Rihanna's proposed online magazine is "identical and/or highly related" to DC products and "consumers are likely to be deceived" into believing the goods and services are associated.
