What to do when competitor copies your app (exact design)
there: your copyright covers your text, design (html and css), and code, so unless you're claiming that they actually stole your code (and then translated it to what looks like asp.net) or are using direct copies of your css or html, i don't think you really have a leg to stand on, legally.someone creating something from scratch that looks like (or "inspired by") your site is not infringing on your copyright at all.  looking at screenshots on the two sites, i can see some similarities, but enough differences that it doesn't look like it was directly copied.  to be honest, though, neither design looks that unique.  one could say you copied the signup chart on your site from 37signals or any of the other dozen sites that look like it since it's so popular.i think your best bet is just to move on and try to be better than your competition.  you can try to call them out publicly, but it will just give them free publicity and drive traffic to their site.
