Mashable reports that Apple has just been granted some patents for the design of the Macbook Air which might affect on the ultrabook market.
The first thing that came to mind was the Asus Zenbook which got its inspiration from from the Macbook Air.

We wrote a review of the Zenbook UX31 here, and noted that there are striking similarities with the Macbook Air.
We also have a side by side comparison of the Macbook Air and Asus Zenbook here.

Intel has promised up to 70+ ultrabooks to come out this year so this will be interesting to follow.
I’m not sure what or how this will affect the production and future designs of other ultrabooks in the market. This patent might just end up the debate on who’s copying who.

It’s also possible that Mac laptops copied other laptop designs.
