The innovative textile machinery and plant engineering company has reported a patent infringement by its competitor, Fujian Xin Gang Textile Machinery Co. Ltd. and, after several years of dispute in court, has been vindicated in the second instance. The proceedings started back in 2021 before the Shanghai Intellectual Property Court. Following an appeal by the KARL MAYER GROUP, the final judgement was handed down by the Supreme People's Court of the People's Republic of China in May 2024. It ruled in favour of the German plaintiff. Fujian Xin Gang Textile's counterclaim for cancellation of the patent in question was dismissed, and the Chinese manufacturer must immediately cease manufacturing and offering to sell the machines with the technical solution that was the subject of the legal dispute. A fine was also imposed.
The subject of the legal dispute was a constructive system for heating the carrying-lever shaft of Tricot and Raschel machines. This clever solution enables the technology leader's machines equipped with carbon bars to compensate for changing ambient temperatures. A patent for the technical innovation was granted in China in November 2011.
