Nadya Suleman, who became a history-making mum after giving birth to octuplets on January 26, is seeking to trademark the word "Octomom".
The 33-year-old, who conceived her 14 kids through in vitro fertilization, has filed an application with the U.S. Patent and Trademark Office to obtain legal rights to the name.
But a Houston-based novelty company was said to have already made a similar request.
"It's not going to matter because they had no permission from Nadya, who has the rightful claim to the name 'Octomom', " People quoted Suleman's attorney Jeff Czech as saying.
The single, unemployed mum-of-14 had previously been out of favour for the word, but made the decision to apply for its legitimate claim after realising the capitalist opportunities associated with it.
Czech added: "She's never warmed to it, but the idea would be for others to use it for licensing. It's just a smart thing to do."
