Düsseldorf Regional Court

Korean solar manufacturer Hanwha Q Cells has told pv magazine a Dutch court which gave it permission to seize a shipment of solar products made by Chinese rival Longi Solar at the warehouse of a storage keeper last month, has confirmed Longi can reclaim the PV products upon proof they will not be distributed in European markets where a Hanwha technology patent applies.

The Chinese solar giant today announced a final written decision published by the American authorities which reportedly invalidates Hanwha Q Cells patents. That development appears to have come 12 days after the Korean manufacturer carried out a seizure of a Longi panel shipment in Rotterdam on the basis of the potential for the infringement of Hanwha patents which apply in Europe.

A shipment of modules from the Chinese solar manufacturer was reportedly seized in the Netherlands last month on the orders of Korean rival Hanwha Q Cells, which persuaded a Dutch court the products might be distributed in third-party nations in infringement of one of its European patents.

The Korean manufacturer today announced it wants to enforce a ruling made in the regional court of Düsseldorf in June which prohibited rival Jinko Solar from making, selling, importing and distributing products which the court ruled had infringed one of Hanwha’s passivation patents.

The Düsseldorf Regional Court has agreed rivals of the Korean manufacturer illegally used its patented passivation technology. The judges granted Hanwha Q-Cells an injunction which requires Jinko, REC and Longi to retrieve all modules featuring the patented technology distributed in Germany since late January last year. Hanwha can also opt to have the offending products destroyed.
