Zynga Sues Vostu, Alleged Copycat Gaming Startup

“Vostu's business model is simple: copy Zynga's successful games,” the lawsuit states. “While imitation may be the sincerest form of flattery, the copying of valuable intellectual property rights is theft.”

Zynga claims that Vostu hasn’t just copied its ideas for games, but that it has replicated every detail, from storylines to in-game items, and even included “mistakes” that appear in Zynga games (like the fact that community buildings in CityVille aren’t connected to roads).

But Zynga has no right to point fingers, Vostu responded in a statement.
