Here come the design patents: new law boosts rights in shapes, designs

I personally don't see the point of design patents. The whole premise underlying the patent system is to prevent free-riding, but shapes are rarely the product of significant capital investment. If the problem becomes one of confusing similarity, then trade dress is the more appropriate vehicle (incidentally, I think if design patents hadn't existed, Apple would've sued Samsung on trade dress infringement grounds).
There is an internal tension in IP law between the economic justifications for the law and, well, the law. The point is to protect expensive capital investment into design from free-riding, but the law is loathe to actually look at whether a design is the product of expensive investment.
The golden question is how deferential US courts will be to a valid US patent with international precedent. Hopefully not at all because these patents are going to be complete crap.
