Meyer Burger to appeal Chinese ruling in patent infringement lawsuit

The Nanjing Intermediate Court has issued a first instance judgment, dismissing Meyer Burger’s claims that Wuxi Shangji Automation has violated the Chinese patent for its Diamond Wire Management System (DWMS).

“This first instance judgement has not yet come into force and Meyer Burger will file an appeal with the Jiangsu High Court within the 30-day time limit by May 17, 2018 or will take all other necessary legal actions against existing or future patent infringements to enforce its patent rights,” said the Swiss solar PV equipment manufacturer in a statement released today.

At the start of February, Meyer Burger filed a patent infringement lawsuit in China claiming that Wuxi Shangji Automation wire saw WSK027BL infringes on its Chinese patent number CN 104411434B.

“We want Wuxi Shangji to stop producing and selling the corresponding system,” a spokeswoman from Meyer Burger told pv magazine at the time.

Meyer Burger claimed it had gathered evidence, together with a Chinese law firm, showing that Wuxi Shangj is using a technology based on its DWMS patented wire wrapping system, which Meyer Burger has developed specifically for its diamond wire saws, and which is used in the production of mono- and multi-silicon PV wafers.
