It is a frequent event that famous people try to trademark their name in order to stop companies making money off it. Last month, it hit the headlines that Victoria Beckham was trying to trademark her daughter Harper’s name, and now Beyoncé is doing the same.

It has been an ongoing battle between Beyoncé and an event company with her daughter’s name. Despite her attempts to trademark Blue Ivy, the event company is also continuing to file court documents to block the ‘Queen’ from trademarking the full legal name of her offspring. The company claims that Beyonce has no right to the name because they have been using it for years.

Beyonce had previously tried to trademark just “Blue Ivy,” but was blocked by the company. So, she tried to trademark “Blue Ivy Carter” and once again the events company were unhappy. Though Jay Z said that the family just wants to preemptively stop anyone from profiting off the name of his daughter, the company claims that the couple have doubled back on that. Blue Ivy — the firm — claims that the pair intends to sell merchandise with their daughter’s name (which also happens to be the name of their business) and want to stop them before they can get there.

Even though Beyonce has added the last name Carter to her trademark filing, Blue Ivy is still trying to stop it from going through.
