| You can find a good summary of the patents & verdict here: http://www.zdnet.com/the-verdict-is-in-samsung-vs-apple-7000... You are correct that it concerns trade dress, but the rounded rectangles were more significant than you give them credit for being. The ZDNet summary helpfully lists the design features at issue for each patent. I'm listing only those that contain rounded rectangles; there were seven patents in all: Design patents infringed? For design patent D'677 (rounded rectangle, edge-to-edge glass, thin bezel, horizontal speaker for phone): Yes for all but Galaxy Ace. For design patent D'889 (rounded rectangle, edge-to-edge glass, thin bezel for tablet): No for all. HN eats the links to these patents from the original summary, so I put them below: http://www.google.com/patents/USD618677 http://www.google.com/patents/USD504889 |
"Rounded corners," by itself, is out-and-out not protectable by a design patent, since they are functional. But as part of a larger body of work they can be. The classic design patent is Coca-Cola on the Coke bottle. It didn't stop other people from using any individual feature of the Coke bottle, but the sum of the features (or close enough) triggers the design patent.
Also, I don't believe there is an official list of just what is covered by a design patent. ZDNet is applying their own editorial judgment there; that's not wrong, but it's also not binding.
