Blac Chyna may not be allowed to use her future Kardashian name for profit after all.
In May, the Rob & Chyna star, who just gave birth to her and Rob Kardashian's first child, filed an application with the United States Patent and Trademark Office on behalf of her company Lashed LLC. to trademark what will become her married name—Angela Renée Kardashian. If her request is granted, she would have the sole right to use the name for advertising and entertainment services, such as TV, movie and promotional appearances.
However, Rob's sisters Khloe Kardashian, Kourtney Kardashian and Kim Kardashian's companies are not cool with this.
Last week, attorneys for the trio's corporations Khloemoney Inc., 2Die4Kourt and Kimsaprincess Inc. filed papers to formally oppose her registration to try to trademark her future married name.
The Kardashian sisters' names are all trademarked. According to the documents, obtained by E! News, the attorneys believe the companies will each "suffer damage, including irreparable injury, to their reputation and goodwill" if her request is granted.
"Their trademark attorneys automatically oppose anyone trying to trademark 'Kardashian,'" a family source told E! News exclusively. "I doubt the girls were even aware."
"Everyone loves each other," the source added. "It's just business."
A statement to E! News from Chyna's attorney read, "Since we are in the midst of litigating this matter, I cannot comment directly at this time. However, I will continue to aggressively represent Angela and work diligently with her to protect and grow her intellectual property."
The sisters' companies' filing states that they "own and control the rights in the 'Kardashian' brand and related trademarks and services marks." They say they have "spent, and continue to invest, a substantial amount of time, resources and money in protecting, advertising and promoting the 'Kardashian' marks" and that "the public has come to associate goods and services bearing the 'Kardashian' marks" with them.
Khloe, Kourtney and Kim's companies accuse Blac Chyna's of "deliberately seeking to profit from the goodwill and popularity" of their "Kardashian" marks. They say that each of them will be damaged by her future name registration, which is "likely to cause confusion, or to cause mistake, or to deceive consumers."
Blac Chyna has not responded to their filing. She has until Jan. 10 to due so and the case could go to trial.
