Victoria Kann, author of the popular children’s book series Pinkalicious, has lost a domain name dispute for Pinkalicious.com.

Kann filed the dispute last month with National Arbitration Forum.

There was a fatal flaw in her case: the domain name was registered well before she started publishing the book series.

Kann argued that she had rights in the “Pinkalicious” mark dating to 2004 when she entered into a contract to publish the series. Of course, no domain owner could have known about her plans in 2004. Also, the trademark she leans on in her case shows a first use in commerce date in 2007.

But none of those dates matter much since the domain was registered way back in 2002.
