An Illegal theme park based on the most popular and grossing smartphone and tablet game from Rovio, Angry birds, has opened in Changsha, Hunan province in China.

The theme park, currently, is facing all sorts of legal issues. The entertainment park was unveiled on Sept. 1 without any permission from the Finland-based company Rovio and has violated several copyrights.

The illegal theme park is yet another instance where China has been blamed for hampering with intellectual property. Previously, in July, an American blogger, residing in China, reported the existence of two counterfeit Apple stores in Kunming, China. The stores, as well as 22 other fake Apple stores, were later shut down by the Chinese authorities.

The park’s marketing manager Ye Xiumei said that an Angry Birds exhibit will be held until the end of September. The park’s existence, however, could allow the Finnish company to file an intellectual property infringement lawsuit.

A spokesperson for Rovio said that the Finnish company is looking forward to a partnership, according to a report.

Angry Birds has been praised for its successful combination of addictive gameplay, comical style, and low price. With a combined 300 million downloads across all platforms and including both regular and special editions, the game has been called one of the most mainstream games out right now, one of the great runaway hits of 2010, and the largest mobile app success the world has seen so far.

In April 2011, Angry Birds won both the Best Game App and App of the Year at the UK Appy Awards, and at the 15th edition of the Webby Awards, the game was awarded Best Game for Handheld Devices.
