Trademark was filed back in the April of 2011.
While Apple has already moved onto OS X "Mountain Lion," the U.S. Patent and Trademark Office has approved Apple's "Lion" trademark.
The U.S. Office of Patents and Trademarks has approved the Cupertino company's trademark after over a year of waiting, with Apple now the legal rights owner to the name for its "computer operating system and application development tool software." The trademark itself is spelled with a capital "L", which is followed by lowercase letters.
A few months before it filed for "OS X MOUNTAIN LION" and "MOUNTAIN LION," Apple filed the request for "Lion" on April 6, 2011. The two former trademarks, however, have yet to be approved.
Apple is no stranger to protecting its trademarks in the past. The firm filed a lawsuit against Amazon last year over the term "App Store," a trademark that the former registered following the release of its iPhone 3G.
The company was also embroiled in a lengthy battle against Apple Corps, who is the Beatles' holding company and owner of the band's record label, over trademark issues, which was settled last week.
