JAY Z & BEYONCE TRADEMARK BATTLE FOR "BLUE IVY'S" NAME!

Even Jay-Z and Beyonce can't have it all.

The hip-hop hotshots may have President Barack Obama's friendship on their side, but the pair officially lost the trademark battle for name "Blue Ivy" this past weekend.

According to Boston's Fox 25, Jay and Bey initially tried to trademark the name in January, shortly after daughter Blue Ivy's birth.

E! News reports that the power couple filed the petition because Beyonce hoped to one day start a line of children's clothing.

Boston event planning firm Blue Ivy vs. Blue Ivy Events in turn defended its right to use the name, which they'd had since 2009.

And ultimately, the U.S. Patent and Trademark Office ruled in favor of the event company, siding with the company's owner, Veronica Alexandra.

Not that the case left a bad taste in the event owner's mouth.

"Congrats to our SOUL MATE Couple with Baby Blue Ivy!!!" the firm captioned a photo of the couple on their site.

Don't Jay already own a shade of Blue called Jay Z blue! What else do you want
