Notice: A company in the Netherlands filed a lawsuit with the court, claiming that Tongyi Zhonghe, an Italian company, was the infringer of its patent EP1126052 "High-strength polyethylene fiber and its application". It accused Tongyi Zhongwei of being involved in the production and production of ultra-high-strength polyethylene fiber. Promote infringement, and propose that Tongyi Zhonghe Italian Company be jointly responsible for temporary compensation and other litigation claims.

The original owner of the EP1126052 patent filed by a Dutch company this time is Japan **Textile Co., Ltd. In 2007, a Dutch company obtained the use through transfer from Japan **Textile Co., Ltd.
