de l'Edition, which joined the lawsuit, said Google has scanned about 100,000 French works under copyright. In December 2009, Chinese author Mian Mian filed a civil lawsuit for $8,900 against Google for scanning her novel, Acid Lovers. This is the first such lawsuit to be filed against Google in China. Also, in November that year, the China Written Works Copyright Society (CWWCS) accused Google of scanning 18,000 books by 570 Chinese writers without authorization. Google agreed on Nov 20 to provide a list of Chinese books it had scanned, but the company refused to admit having "infringed" copyright laws. In March 2007, Thomas Rubin, associate general counsel for copyright, trademark, and trade secrets at Microsoft, accused Google of violating copyright law with their book search service. Rubin specifically criticized Google's policy of freely copying any work until notified by the copyright holder to stop. Google licensing of public domain works is also an area of concern due to using of digital watermarking techniques with the books. Some published works that are in the public domain, such as all works created by the U.S. Federal government, are still treated like other works under copyright, and therefore locked after 1922.
