Kylie Minogue has been in the entertainment spotlight far longer than Keeping Up With the Kardashians star Kylie Jenner. That’s why the “Can’t Get You Out of My Head” singer is opposing Kylie Jenner’s application to trademark her first name.

According to a report from Billboard, Kylie Jenner filed for protection of her first name. Last week Kylie Minogue filed “a notice of opposition to the application.”

KDB is the Australian-based business representing Kylie Minogue. They argue that if the US Patent and Trademark Office approved Kylie Jenner’s application then it would cause confusion among consumers and hurt the pop singer’s brand.

Kylie Minogue has sold in excess of 65 million albums throughout her decades-long career. The recipient of Brit Awards and Grammy Awards, she became the first-ever woman (and first foreigner–she is from Melbourne, Australia) to receive Britain’s Music Industry Trusts’ Award in 2011.

Something else that likely irks Kylie Jenner to no end is Kylie Minogue’s ownership of the kylie.com domain. Kylie Minogue purchased the domain name in 1996, a year before Kylie Jenner was born.

How do you suppose this war of “the Kylies” will end? Do you think Kylie Jenner has the right to copyright her first name?

It seems quite likely, since Kylie Minogue has been in the entertainment limelight for so much longer than Kylie Jenner, that she will win this battle.
