A new Apple patent may signal legal wrangling ahead for the Windows laptop wedge design crowd -- which means pretty much every major PC maker on the planet.
The patent documentation states that "the broken lines are for the purpose of illustrating portions of the electronic device and form no part of the claimed design," as The Verge points out.
So that seems to exclude aspects of a laptop's external design that are not material to the wedge contour itself such as a unique hinge component.
Of course, all this hinges on (pun intended) how aggressively Apple defends its patent: the wedge design is really an imperative for any ultrabook maker because the tapered design allows a laptop to be thicker where it needs to be -- e.g., the back hinge -- and thinner at the front, economizing weight and average thickness.
And there are degrees of likeness to the wedged MacBook Air. Some ultrabooks have more of a likeness to the MacBook Air than others.
Also, don't forget that it's the newer MacBooks announced back in 2010 that have the most pronounced wedge design. Earlier versions of the Air had much more subtle tapering and "wedge" was not typically used to describe those 2008 and 2009 designs.
