While Beyoncé and Jay-Z have yet to officially confirm the birth, sex, or Names of their twins, a lot of details have emerged from other sources. Beyoncé's father, Mathew Knowles, previously confirmed the birth of the twins last month when he posted a tweet that welcomed the new babies and wished them a happy birthday. Now, the names of the twins might have just been revealed via some newly acquired legal documents filed with the U.S. Patent and Trademark Office by the couple's company earlier this week.

Brand names

The couple's company BGK Trademark Holdings LLC, BGK stands for Beyoncé Giselle Knowles., recently filed a trademark for the names "Sir Carter" and "Rumi Carter." The documents were filed by their lawyer, Jonathan D.

West, with U.S. Patent and Trademark Office to trademark the names for different baby-related products and services. The products that are listed on the patent included items such as baby carriages, strollers, baby teething rings, tote bags, and other baby gear. The patent also specifically mentions other products not necessarily related to babies, which includes bags, mugs, shirts, online video games, key chains, and other items.

A clear connection

Given the nature of the patent and its sudden submission, it would likely be safe to assume that the couple is thinking ahead and are just trying to protect their new children's inescapable popularity from being exploited. It would be very easy for manufacturers and other baby-related businesses to utilize the twin's names to promote their own products if no legal restrictions were put in place.

TMZ was the first to conclude that "Sir Carter" and "Rumi Carter" may, in fact, be the names of the twins, presumed to be a boy and a girl. The connection is there and it does make a lot of sense for the couple to trademark their babies' names to prevent any legal issues in the future.

Meaning behind the names

If the names are indeed for Beyoncé and Jay-Z's twins, then they are indeed quite unique as the names are not really very commonly used in the United States.

Rumi is traditionally a Japanese name, but it is also the name of a thirteenth-century Persian poet. Jalāl ad-Dīn Muhammad Rūmī is considered to be the best-selling poet in the US and was a renowned thinker and writer. "Sir," on the other hand, is traditionally a title that is given to a man of distinction who has been knighted by the Queen or King of the United Kingdom. Although given the fact that Beyoncé and Jay-Z named their first child Blue Ivy, naming their newborns Rumi and Sir may not be as farfetched.
