This winter, Jay-Z and Beyonce took the "cutthroat" competition to coin the most original baby name to a new level, when they trademarked "Blue Ivy" to ensure other new moms and dads wouldn't copy the name of their new daughter, born Jan. 7 in New York City. Are we in for a wave of parents staking similar claims on baby-name turf? Here, a brief guide:

Why did Beyonce and Jay-Z get so protective about a name?
It's all about the brand. The recording stars most likely reserved the name of their wee A-lister "for a future line of baby clothing or kiddie items with the label Blue Ivy Carter on it," says tax lawyer and mom Jacoba Urist at MSNBC. So if you're hoping to "capitalize on their kid's fame and open up your own Blue Ivy boutique," you're out of luck.

Can non-celebrities follow their lead?
Technically, yes. But you'll gain little advantage, at least "99.9 percent of the time," Brett Frischmann, an expert in intellectual property and internet law at Cardozo School of Law, tells MSNBC. A trademark doesn't stop other parents from giving their kid your child's name. It just stakes a claim in the business world; it only becomes an issue if they try to profit off the name. "You could always name your child Delta and the airline couldn't sue you," unless you built a rival, identically named airline around your new offspring.

What's an ordinary mom or dad to do?
Relatively rare names can catch fire quickly. The names Sophia and Jacob, considered rather "original" a decade or so ago, were the most popular names in 2011, according to the Social Security Administration. So many parents are opting for excessively creative spellings to make sure nobody "steals" their baby name, the STFU Parents blog at Mommyish said in December. (How many "Maddilhyns" do you know?) Today's parents will stop at nothing, it seems, to come up with unique names, "so that their kids have a better chance of being 'noticed' as they go through life."
