It's called "trade dress" and it isn't uncommon. Seven Towns claims ownership of its Rubik's Cube color scheme for example. Recently Apple successfully sued Samsung on trade dress grounds for the visual similarity of their products. It's look-and-feel infringement. If the claimant has a powerful enough brand and can show enough similarities, they can easily prevent competitors from diluting their trademark with a trade dress infringement argument.
