Kylie Minogue is not about to let Kylie Jenner trademark the name “Kylie.”

Kylie Minogue v. Kylie Jenner

Jenner, 18, filed a USA trademark application for the name “Kylie” last August for “advertising services, namely, promoting the brands, goods and services of others; endorsement services, namely, promoting the goods and services of others,” reported Fox News. Last month, Minogue took steps to stop her.

Minogue, 47, filed a notice of opposition to Jenner’s application on Feb. 22. In her filing, the Australian pop singer suggested that if Jenner trademarks the name, it will confuse her audience and dilute her brand. Minogue currently has “Kylie” trademarked for entertainment and music recordings. She also owns trademarks for “Kylie Minogue Darling,” “Lucky – The Kylie Minogue Musical” and “Kylie Minogue.”

Furthermore, Minogue’s website, which has been operational since 1998, is Kylie.com.

Minogue’s notice of opposition to Jenner’s attempt to trademark “Kylie” refers to her as a “secondary reality television personality who appeared on the television series Keeping Up With the Kardashians as a supporting character, to Ms. Jenner’s halfsisters.”

The notice further calls into question Jenner’s social media presence – “where her photographic exhibitionism and controversial posts have drawn criticism from, e.g., the Disability Rights and African-American communities.”

Minogue has since taken to Twitter to allude to the trademark battle, writing, “Hello… My name is KYLIE #lightyears.”
