NEW YORK (CNN/Money) - First a hit reality TV show, now an online business school?

Billionaire Donald Trump has applied for a trademark for the name Trump University.

Donald Trump may be on the prowl again, and this time no one needs to audition to become his apprentice.

The Donald, as he's called by New York's tabloid newspapers, has filed an application with the U.S. Patent and Trademark Office to secure a trademark for the Trump University name, CNN/Money has learned.

The proposal was filed Aug. 4 on Trump's behalf by the New York law firm Proskauer Rose, according to the trademark application. The story was first reported on TheSmokingGun.com.

The law firm declined to comment. Trump's offices did not return calls.

It wasn't clear what position the 58-year-old Trump, a graduate of the University of Pennsylvania's respected Wharton School, will hold at the university and when the virtual school will be launched.

The real estate mogul, who according to Forbes is worth $2.5 billion, has been in the news lately. His casino group, Trump Hotels & Casino Resorts Inc., filed for bankruptcy protection from creditors, and his hit reality TV show "The Apprentice" is due to start its second season in September on NBC.

Trump is currently engaged to his Slovenian girlfriend, the raven-tressed model Melania Knauss, but no date has been set for the wedding.

His previous two marriages ended in high-profile divorces.
