From China Law Blog:
Yesterday, I did a post, entitled, “Taking On China Patent Infringment At Home,” extolling the success of a U.S. company that sued a Chinese company in U.S. Federal Court for patent infringement. Today, I came across a good article from law.com [subscription required] on a U.S. company, 3M, that successfully sued a Chinese company in Chinese court for patent infringement. 3M has been in China since 1984, when it became the first U.S. corporation to set up a wholly owned subsidiary (WFOE) there.

But after more infringing masks, traced back to Dasheng and two other Chinese companies, started appearing in Europe, 3M decided it needed to go after the source.[Full Text]
