The US reality star filed paperwork with officials at the US Patent and Trademark Office in 2015, aiming to register 'Kylie' as a trademark for various business purposes.
However in February last year, lawyers for the Australian pop star registered their opposition to Jenner's plan, stating that her trademark application would "bring on confusion for both the celebrities and their brands."
The US Trademark Office officials have now sided with Minogue and refused to accept Jenner's application to use the "Kylie" trademark.
In last year's filing, Minogue's legal representative refers to Kim Kardashian's younger sister as a
"secondary reality television personality" and also raises concerns about Jenner's social media activity.
"Ms Jenner is active on social media where her photographic exhibitionism and controversial posts have drawn criticism from Disability Rights and African-American communities," her attorney wrote.
