Kendall and Kylie Jenner aren't taking any chances when it comes to their personal brands. In April, the reality stars filed various trademarks [1] to protect their names for "advertising services" and "entertainment" purposes, according to reports. They've also filed trademarks for combinations of their respective names, including "Kendall and Kylie" and "Kendall & Kylie."

The efforts go beyond their famous monikers — back in August, Kylie reportedly filed to protect "Kylie's Lip Kit . . . For the Perfect Pout," suggesting she just might try to monetize the #KylieJennerChallenge [2]. It's all just the latest in a string of business moves the Kardashian-Jenners have made [3] over the years.
