Energy efficiency solutions provider LJUNGSTRÖM settles patent infringement suit against manufacturer in China

WELLSVILLE, New York, Nov. 1, 2016 /PRNewswire/ — LJUNGSTRÖM is determined to protect its rights to its air preheater technologies. Some Chinese customers had made complaints about poor quality products that were found to be copycat versions of the LJUNGSTRÖM patented DNF® heating element. After identifying a manufacturer in South China who had been supplying an inferior copycat product, LJUNGSTRÖM filed a patent infringement suit in the Jinhua, Zhejiang court in early 2016.

A settlement agreement has been reached with the manufacturer to cease its infringement of LJUNGSTRÖM’s patent and to pay substantial damages for past infringements. This proves once again that only LJUNGSTRÖM is in a position to supply genuine DNF® heating elements, manufactured to the quality standards and extended operational life required to meet the critical power needs of the people of China.
