Apple is facing a lull in innovation and is need of another era of "creative leap" seen in the past decade when it introduced hugely successful gadgets like the iPhone and iPad, said ex-CEO John Sculley.

"We're in a period now where there's kind of a lull in innovation so I wouldn't expect to see a creative leap from Apple for maybe a few years," Sculley, who was at the helm of the company from 1983-1993, told CNBC Asia's "Squawk Box" on Thursday.
