Rovio Entertainment has filed a trademark infringement lawsuit against Young Star Toys & Gifts et al. claiming that the company is selling "counterfeit knockoffs" based on its popular Angry Birds games and characters.
The lawsuit was filed on July 22 in the California Central District Court against the Vernon, California-based company and its president Brian Yang (who is also the agent in residence, which means he deals with all legal issues including lawsuits).
Rovio alleges that the company is knowingly selling products that are not officially licensed by Rovio or one of its partners. One of Rovio's most prominent revenue streams outside of selling its games is in licensing its characters.
Details on the lawsuit at this point are thin, but we'll have more on this story as it becomes available.
