I think we need to cover what makes patents bad. One of the things that make software patents bad (only one of them) is the fact you can't be certain whether you infringe them, even when you have the patent right in front of you. This is due to ambiguities in the patent. You simply cannot know which way claim construction is going to go.
If you aim is not to infringe a patent, you must avoid the most broad interpretation the patent has, since you never know how that is going to be interpreted.
Back to our design patent. The bezel is clearly marked with a dotted line. To the best of my understanding, that means it is not a part of the patent. The same goes for the earphones jack location and the charging socket. Moving any of those around not will cause you to not infringe the patent. Probably. I think. To the best of my limited understanding.
Basilbrush is trying to claim that the aspect ratio, clearly part of the solid lines, is part of the patent. Just as clearly, however, Apple did not think so. That means that whether he (she?) is right or wrong is irrelevant. When you are trying to avoid infringement, you had !@$#%!@# better assume a different aspect ratio will not save you.
Which brings us back to the bezel. At trial, Apple has a clear interest to show the patent as being as narrow as possible, while still including whatever it is Samsung has done. Make the patent seem too broad, and the jury might think it is invalid. So it is entirely possible that Apple bringing up the bezel was a strategic move.
Of course, they are safe to bring it up as, at the point, they already knew what Samsung did and did not do. It is entirely possible^H^H^H^H^H^H^H^Hlikely that, given other circumstances, Apple would have claimed that the bezel means nothing at all, but the color has to be different, or that the bezel and the color are both irrelevant, but having a logo would have changed everything. Apple's strategy during the trial is dictated by Samsung already past actions.
Discussing what a patent covers, however, pertains to future actions and future litigation. Combining all the different, often conflicting, ways to read this patent yields just one strategy to avoid infringement: don't use rounded corners.
So whether Basilbrush is right or not, the patent covers "hand held device with rounded corners" (the hand is marked with solid lines, so I think it is safe to say it is mandatory). Anything else is a risk.
