"Kendall & Kylie" Come Out Swingin' In Trademark Battle

What's in a name? A whole lot, especially if you're part of reality television's first family.

Taking their cues from "momager" Kris plus their older siblings, Kendall and Kylie Jenner have officially filed applications to copyright their names (both individually and as "Kendall & Kylie") in a bid to assert themselves as global brands.

According to TMZ, the sisters are trademarking their names for 'entertainment in the nature of providing information by means of a global computer network in the fields of entertainment, fashion and pop culture.' They're also claiming their names for personal appearances 'by a celebrity, actress and model,' and could prosecute other stars using their first names if it becomes a source of confusion (wait till Kylie Minogue, 46, gets wind of this, considering her legacy as a pop star since the 1980s).

The increasingly business savvy approach the Jenner girls are applying to their daily lives comes as no surprise. Less than two years ago, older sister Kim Kardashian made moves with husband Kanye West to patent daughter North's full name. A source said at the time, "Kim and Kanye are extremely business-minded but the decision to patent their baby's name also comes from their protectiveness about privacy."

Despite current rumors of a growing rift between the pair, both Kendall and Kylie recently posted hints to their social media accounts of a major joint clothing line in the works.
