Chinese writer Mo Yan's Nobel Prize in literature has led to Mo-mania sweeping the nation, but as publishers rush to reprint the laureate's works, confusion reigns over the copyright status of his books.

In a bid to curb piracy, Beijing Genuine and Profound Culture Development Co, the claimed copyright holder of Mo's work, announced on Monday the details of Mo's copyright, and released Mo's letter of authority on the company to beat piracy, which had been witnessed by officials from the State and the Beijing municipal copyright authorities.

The company's legal representative said they are aware that there are dozens of versions of Mo's books on the market, and 15 publishers claim to have the right to Mo's works, including the digital rights. "Most of which are unauthorized, and we are yet to collect more evidence to take legal action," said Chen Zhongye, Guantao Law Firm partner.
