We had a similar situation several years ago with our site:

http://www.sparkfun.com

And this Chinese knock-off:

http://www.geeetech.com/

Not only did they rip off our design but they also use a bunch of our product photos. We himmed and hawed about doing something about it but ultimately realized there really was nothing we could do to enact any real change. At the end of the day any site's CSS is open source by virtue of the technology (and our product images were already CC BY-NC-SA 3.0 licensed anyway).

So we said screw it. We decided that the best way to assert this design was our own was to run a better website, and more so, just run a better business. In the end it hasn't dented our traffic. GE Tech looks sort of like SparkFun but it sure is a lot more rough around the edges. We've continued to refine our design with less of a Geocities palette while never really caring what those Chinese ripoff artists are up to. It's irrelevant. We'll continue to define our web presence without using them for context, and if they continue to grab skin-deep features from us then terrific - we're a source of inspiration and should be proud.
