As reported on Patently-O,
Earlier this week, the USPTO issued a design patent to Google that covers the "ornamental design for a graphical user interface [GUI] … as shown and described." Pat. No. D. 599,372. Design patent coverage is essentially defined by the images include in the issued patent. Here, the image looks roughly the same as the company's ubiquitous Google.com homepage. (See image below.)To be clear, many patent professionals would argue that it is misleading to ever simply call this "a patent." Rather, it is a design patent. Design patents have severely limited scope, only cover ornamental designs rather than technological advances, and are very frequently found invalid when challenged in court. The USPTO has been granting design patent protection for screen shots and icons for many years. However, to my (limited) knowledge, none of those design patents have ever been enforced in court. ...
Dashed or "ghost" lines in the drawing indicate features that are not claimed. Thus, patent would be infringed by someone using an identical layout even if they replaced the "Google" mark with their own mark. You can note at the bottom that the design patent drawing is marked with a circle-c ©. That indicates that Google is also claiming copyright protection for this layout. In addition, in the design patent, Google indicates that it is also claiming trademark protection for portions of the layout and - perhaps - for the layout as a whole.
