A few days ago, the Quanzhou Intellectual Property Protection Association gave full play to its "professional + expert" advantage to help a company win a patent infringement lawsuit.

Polyurethane (PU) foam is an important industrial raw material. Because of its wide range of uses, the leftover materials and waste materials produced during the production process are quite large. How to recycle waste polyurethane foam to reduce its environmental pollution and impact has attracted more and more attention in recent years. The method of polyurethane foam produced by reusing waste polyurethane foam waste has been publicly introduced by many related patents and scientific and technological documents. Polyurethane foam is prepared by using MDT or TDI and PPG as the main raw materials. The usual process steps and raw material formulations have been well known to technicians in the field.

A shoe material company in Jinjiang (hereinafter referred to as the Jinjiang company), according to the known technology and methods of the industry, produces and sells PU products which are widely welcomed by the market for its high quality and low cost. It is used as the best material for shoes, shoes, hot cushion and other elastomers. But in Dongguan, Guangdong, a bubble cotton plastic company (hereinafter referred to as the Dongguan company), on the basis of its invention patent, accuses the patent infringement of Jinjiang company.

Jinjiang company has found the intellectual property protection association of Quanzhou, and requested to provide advice for them. After investigation and evidence collection and organization of relevant technology and patent experts, Quanzhou intellectual property protection association has provided professional and comprehensive litigation materials and responding strategies for Jinjiang companies. Finally, the court decided that there was no infringement in Jinjiang company. The success of the lawsuit saved the products and market of Jinjiang company, and also removed obstacles for its future development.
