Again, you and LayerVault don't seem to understand copyright.

Here's an example. There's a famous iPhone game called Fruit Ninja. There's another game called Veggie Samurai. Total ripoff in every imaginable way, but completely legal.

Copyright means you can't make direct copies or derivative works of my stuff. It doesn't mean you're not allowed copy all my ideas.

And you don't seem to understand what LV is actually alleging.

And neither do they (LV).

Trademark is not copyright.

The DMCA is for direct copies of IP. This dispute is better resolved with a civil court case because the ownership is non-obvious. It was a very clear misuse of the DMCA and I hope the victim receives some compensation.
