Hanwha Q CELLS once again recognized for its technology, receiving a patent validity judgment in the “patent invalidation trial” for Q CELLS cell technology filed in China by the Chinese solar manufacturer LONGi Solar. LONGi Solar filed two invalidity proceedings against Q CELLS in July and August of 2019 in China’s Reexamination and Invalidation Department of the Patent Office, CNIPA. They alleged that the company’s patents regarding high-efficiency silicon solar cells were invalid. The Patent Office early in November this year ruled in favor of Q CELLS by upholding the validity of its patents. The Patent Office’s determination reaffirmed that Q CELLS’ intellectual property rights can be protected in China, a market where most of global PERC cell are produced currently.
Based on the European equivalent of one of the two patents recently upheld by China’s Patent Office (‘971, equivalent European patent EP 2 220 689), Q CELLS has filed a litigation against three companies – JinkoSolar GmbH, REC Solar EMEA GmbH, and LONGi Solar Technologie GmbH – in Germany for PERC patent infringements.
The Regional Court of Düsseldorf, Germany in June decided that JinkoSolar, REC and LONGi Solar infringed Q CELLS’ patent. Appeal proceedings and parallel invalidation proceedings are pending. The first instance judgement is provisionally enforceable against provision of a security. Q CELLS provided that security and decided to enforce the judgment. Following the court ruling, sales of the infringing products in Germany and imports have been prohibited, and recall and destruction obligations have been imposed against the affected products distributed after January 30, 2019.
“This win is a truly valuable achievement given that Q CELLS’ exclusive technology has been recognized not only in the solar power sales markets but also in the production markets,” said Dr. Daniel Jeong, Chief Technology Officer at Q CELLS. “Q CELLS will continue to do its best to protect our intellectual property and continue to drive innovation while promoting sound competition for the solar industry.”
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
