San Francisco — Zynga, the social games publisher behind titles like “FarmVille,” has filed a lawsuit against fellow social games publisher Vostu for copyright infringement of its “creative works.”

Brazil-based Vostu allegedly copied every aspect of Zynga’s games. Reggie Davis, general counsel for Zynga, wrote in a statement on Friday that the Brazilian company copied all of their “key product features, product strategy, branding, mission statement and employee benefits.

“We welcome Vostu into the arena of social games, but blatant infringement of our creative works is not an acceptable business strategy — it is a violation of the law.”

It should be noted that Vostu has to date raised more than $45 million in venture capital financing, from high-profile backers including Intel Capital, General Catalyst Partners and Accel Partners.

Zynga filed the lawsuit Friday in federal court in California.
