What exactly was cloned? The look of it? They still had to mill the thing from aluminum, design the components to fit and operate well, and everything else that comes with developing a laptop. It's not like they even took Apple's frame and copied that verbatim.

In fact, they went a step further by including some features that a Macbook doesn't have. Apple doesn't have exclusive rights on aluminum frames or the color silver. Or black keys... so what exactly did they clone, really?
