She's just a month old, but Blue Ivy Carter is already a household name -- and her world-famous parents Beyonce and Jay-Z aim to protect it.

Rolling Stone reports that the new mom, 30, and dad, 43, filed an application with the U.S. Patent and Trademark Office to protect their daughter's name; the music superstars intend to use Blue Ivy as a potential brand name for a line of baby products, including carriages, diaper bags and baby cosmetics.

The application (made through Beyonce's company BGK Trademark Holdings) is pending, but is expected to be approved.

The "Love on Top" singer and "Empire State of Mind" rapper's move comes after two competing trademark applications emerged following Blue Ivy's Jan. 7 birth. Fashion designer Joseph Mbeh tried to trademark "Blue Ivy Carter IV" on Jan. 11; another applicant tried to claim the name "Blue Ivy Carter Glory IV" for a line of fragrances. Both applications were denied.
