07 七 10 Global wind turbine giant intensified patent lawsuit

Currently, wind power generaotor is in the process of industrialization. U.S. Department of Energy released data show that the total U.S. wind power installed capacity of 2.47 MW from 1999 to 2009 of 34.86 MW. In 2007 to the end of 2009 these 3-year growth is particularly rapid, the additional capacity of nearly 2000 to 2006, 7 years to 3 times the additional capacity.
Since 2002, the U.S. patent issued over 800 wind turbine parts. Denmark’s Vestas Wind Systems, Germany 阿洛伊斯沃 this, Japan’s Mitsubishi Heavy Industries and General Electric are the United States holds the patent more than wind turbines. GE’s small wind turbines in which nearly 150 patents, came out top. General Electric is the largest U.S. supplier of wind turbines. According to the American Wind Energy Association estimates that in 2008 the U.S. General Electric wind turbines account for 43% of the market, and has more than 10 companies through licensing its patented technology. However, GE’s market dominance by Mitsubishi Heavy Industries challenges. Mitsubishi Heavy Industries in 2007, announced its 2.4 MW wind turbine units in the United States has received 411 orders. Alone order to close the nation’s total installed capacity by 2009 3 times. General Electric in early 2008 in the United States International Trade Commission (ITC) launched 337 proceedings, sued Mitsubishi for infringement of common wind turbine U.S. patent US5, 083,039; US6, 921,985, and US7, 321,221.

January 8, 2010, the International Trade Commission’s six members of the Mitsubishi Heavy Industries of determination after review of the wind turbine generator does not infringe GE’s patents, without violating Section 337, so as to Mitsubishi 2.4 megawatt wind generators into the U.S. market exclusion a roadblock. However, General Electric, do not be to hand over the market, claiming to appeal the ruling of the International Trade Commission, and on February 11, 2010 Federal District Court in Texas alleging infringement of its U.S. patents Mitsubishi Heavy Industries, US6, 879,055 and US7, 629,705. In this regard, Mitsubishi Heavy Industries is not weakness, in the May 20, 2010 in the United States Court of Arkansas Western Federal antitrust suit against General Electric violations, abuse of patent litigation against competitors, threatening small wind turbine users. On the same day, Mitsubishi Heavy Industries is also in Central Florida to the Federal Court infringement lawsuit against General Electric, U.S. Patent US7, 452,185.
