MICHAEL JACKSON’s father has hit out at the owners of the King of Pop’s Neverland Ranch for failing to ask the family for permission before applying to trademark potential property names should it be turned into a public museum.

Bosses at Sycamore Valley Ranch Company, which was founded by the late superstar and executives at private equity firm Colony Capital, have filed paperwork with the U.S. Patent Office to acquire the rights to four names they want to use in conjunction with the sprawling estate.

According to TMZ.com, they want to trademark Neverland, Neverland Ranch, Neverland Valley and Neverland Valley Ranch - and they’ve also moved to secure the patents to various products and services in the event the company wins approval to turn the place into a space for fans.

Legal documents reveal Sycamore Valley Ranch Company bosses want to use the four Neverland names for “museum services… providing tour and theme park services”, clothing, games and toys.

But the Thriller hitmaker’s dad Joe Jackson is upset by the plans - because he claims the family was never approached to discuss the idea of patenting.

And he hints the Jacksons will fight to block the idea of a public museum if Neverland’s owners don’t share their plans with the star’s grieving relatives.

The family patriarch tells the website, “Colony Capital cannot do this without our permission.”
