Chinese court ruling favors AMSC

American Superconductor Corp., a Devens company that makes software used to manage energy grids, said that China’s Supreme People’s Court has ruled in its favor on jurisdictional matters in its ongoing lawsuits that allege copyright infringement by a former Chinese customer that makes wind turbines.

The company, once AMSC’s largest customer, is Sinovel Wind Group Ltd.

In four legal cases that AMSC brought in 2011, AMSC claims that Sinovel breached its contract with the US company and allegedly stole its technology. AMSC is seeking $1.2 billion in damages and reimbursements.


Sinovel has repeatedly denied that it engaged in intellectual property theft.

As part of its legal battle against Sinovel, AMSC is pursuing two copyright infringement cases. Sinovel attempted to have those two cases dismissed on jurisdictional grounds.

On Wednesday, AMSC said that China’s Supreme People’s Court decided the two cases would be heard in the court system, rather than in arbitration.

In those two cases, AMSC is seeking about $6.2 million and court orders prohibiting Sinovel from using AMSC’s technology. AMSC’s larger legal actions against Sinovel are still pending.
