It was always inevitable that the children of Kylie Jenner, plus Kim and Khloe Kardashian, would become a part of the family empire. 

According to TMZ, the three aforementioned sisters have filed documents to trademark the names of their children, including Saint, North, and Chicago West, as well as True Thompson and Stormi Webster. The documents obtained by TMZ say that the purpose of this was to put the names of the kids on products that include a clothing line, skincare products, and toys (among other things).

Jenner also went so far as to trademark "Stormiworld" as what seems to be a play on Travis Scott's Astroworld album. The family also intends to sign endorsement deals for the purpose of distributing other, thus far unknown, products.

In other news that's related to the Kardashian family and their business, Kim is reportedly being sued for $100 million over her Kimoji app. 

David Liebensohn is claiming that he helped out with building the app but wasn't properly compensated, according to TMZ.
