Making himself heard loud and clear to the media on July 19, General Protecht Group (once known as Zhejiang Dongzheng Electrical) President Chen Wusheng announced his company's   victory over US electrical giant Leviton after three years of close quarter battles, ending Chinese companies' winning drought in US patent litigations.  A US media comments "its political significance way outweighs any commercial value".

In April 2004, Leviton brought suits four of General Protecht's important customers in the district courts of New Mexico, Florida and California.  After 3 years,on July 10, 2007, Federal District of New Mexico Judge James Browning awarded summary judgment of non-infringement, in favor of General Protecht. The order found that the General Protecht GFCI (ground fault circuit interrupters) devices at issue do not infringe upon Leviton's asserted patent 6246558. 

Then litigation-happy plaintiff Leviton is now in a torrid bid to settle with General Protecht. "We have unwavering faith in the case and we win,"Chen can not wait to share the news to the media.
