Hanwha Q Cells exps Australian patent infringement lawsuit to include REC, BayWa r.e., Sol DistributionTags£ºHanwha  REC  BayWa r.e. 

South Korean solar module maker Hanwha  Q Cells has filed a patent infringement lawsuit against Norwegian solar manufacturer REC  Group, claiming its rival has used its patented solar cell passivation technology to increase the performance of its own products. The complaint against REC also claims that Sol Distribution BayWa r.e.  Solar Systems have distributed REC products in Australia that infringe on Hanwha Q Cells’ patented technology.

The new claims come off the back of separate lawsuits that Hanwha Q Cells lodged against Chinese panel makers Jinko Solar Longi Solar in Australia just weeks ago.

The Australian patent fight follows similar allegations in the U.S. Germany. At the start of this month, Hanwha Q Cells lodged a patent infringement lawsuit against Jinko REC in Germany, as well as two more against the same companies plus Longi in the U.S., based on the same claims. In complaints lodged with the U.S. International Trade Commission (ITC), the U.S. District Court in Delaware the Regional Court of Düsseldorf, Hanwha Q Cells is seeking court orders to prohibit its rivals from importing selling products it claims are in violation of its patents.

In a statement released by its Australian arm, Hanwha Q Cells said the latest lawsuit was lodged with the same aim, to stop the three companies from importing, marketing selling what it claims are products that violate its patents in Australia.

“We do not tolerate the infringement of our intellectual property rights we will vigorously defend our technology from being unfairly used,” said Hee Cheul (charles) Kim, chief executive officer of Hanwha Q Cells & Advanced Materials Corp. “Hanwha Q Cells remains fully committed to serving the needs of the Australian market we have no intention to cause inconvenience to customers, be they EPC contractors, distributors, or installers. We believe these legal actions will contribute to the long-term, healthy development of the solar energy industry.”

REC’s response

REC said it was investigating the claims in Germany the U.S. would take all necessary steps to defend itself against patent infringement allegations. It also confirmed at the time that it had not received any notifications from the U.S. District Court in Delaware in relation to one of the two lawsuits filed against it by Hanwha in the U.S. Regarding the second case, REC said the ITC had received an infringement complaint from Hanwha had 30 days to carry out a preliminary investigation. If the ITC decides there is a case to answer, it will contact REC.

Meanwhile, it was confirmed that Hanwha Q Cells has paid a fee to the Duesseldorf district court, which was a precondition for legal action to begin in Germany. The court has ordered a written preliminary procedure for the defendants to show their readiness. “At a later date, a hearing date will be determined,” a Duesseldorf district court spokeswoman told pv magazine mid March.

Jinko has categorically refuted allegations that it was using Hanwha Q Cells’ passivation technology on its cells, adding it did not expect any disruptions to normal operations as a result of the lawsuit. “Based on Jinko Solar’s preliminary analysis of Hanwha’s complaints the asserted patents, the company believes that the complaints are without technical or legal merit,” Jinko said in an earlier statement.

Noting that it had not yet been notified of legal action by its Korean rival, monocrystalline module maker Longi claimed there was considerable uncertainty over the validity of the patents at the root of the lawsuits. The Xi’an-based company said the disputed patents related to atomic layer deposition (ALD) technology. Longi said it uses a plasma-enhanced chemical vapor deposition (PECVD) process.

As noted in Hanwha Q Cells’ earlier statement, the Australian patent claims are not restricted to any method of manufacture, such as ALD or PECVD. Hanwha Q Cells says the claims — their equivalents in the U.S. Germany — are directed at a solar cell structure with a first dielectric layer including aluminum oxide a second dielectric layer that contains hydrogen.

In a statement filed to pv magazine on Monday, BayWa r.e. dismissed Hanwha Q-Cells’ claim, noted its day-to-day business would not be affected. “BayWa r.e.’s view is that the claim filed by Hanwha against BayWa r.e. is without technical legal merit. BayWa r.e. fully respects intellectual property rights takes any allegations to the contrary very seriously,” said Durmus Yildiz, Managing Director of BayWa r.e. Australia.

“BayWa r.e. will continue to investigate the allegations co-operate with its supply chain partners to take all steps necessary to defend itself against the claim,“ Yildiz added, noting the company will continue to keep its customers partners fully apprised of any developments.

pv magazine has approached REC Group Sol Distribution for comment on the Australian lawsuits.
