BEYONCE AND JAY-Z CANNOT TRADEMARK BLUE IVY AND LOST IN COPYRIGHT COURT.

Beyoncé and Jay Z have lost their legal bid to trademark their baby daughter Blue Ivy’s according to the Boston Herald. The U.S. Patent and Trademark Office turning down their petition to retain “Blue Ivy” for their own business ventures" I wonder why? According to reports, a wedding planning company called Blue Ivy Events will get to retain its good name, at least, in the esteemed eyes of the U.S. Patent and Trademark Office. So if Beyonce and Jay-Z wanted to launch a similar venture, they couldn't use their daughter's name to do it.

However, experts say, the development does not stop the Carters from moving forward in their push to trademark Blue Ivy in all the other areas they've earmarked. Like, you know, electric hair curlers and non-medicated hair care preparations. If they want. (Beyoncé's rep didn't immediately return a request for comment.)

So to be clear: The decision simply states they can't use the name for a wedding planning business. But experts say they can still trademark it for other things.

"No judge ruled that Beyonce and Jay-Z do not have a legal right to protect the name," explains Greenberg Glusker attorney Aaron Ross. "A trademark examiner determined that a Boston company, which began using the name Blue Ivy first, is entitled to register the mark in the field of event planning."
