Warm congratulations to Yanyi Group for successfully obtaining multiple utility model patent certificates once again! This not only affirms the Group's technological innovation capabilities but also serves as an important milestone in its continued leadership in the door and window industry. The five newly acquired patents cover: pressure-line structures for window frame glass, magnetic-attraction split-type screen windows, embedded components to prevent window frame drainage blockages, window frames with E-shaped sealing grooves, and window frames featuring drainage structures - each demonstrating Yanyi Group's profound accumulation and innovative spirit in product design and functional optimization.

As one of China's three major patent types, utility model patents primarily protect novel and practical technical solutions related to a product's shape, structure, or their combination. These patents from Yanyi Group not only enhance product functionality but also improve user experience, fully showcasing the company's technical strength and market competitiveness in the door and window industry.

In recent years, Yanyi Group's continuous investment in scientific research and production technology has not only resulted in the authorization of multiple utility model patents but also seen several patent applications actively submitted to the National Intellectual Property Administration pending approval. Yanyi Group places great emphasis on the development of independent intellectual property rights, both to effectively protect its knowledge and operational rights in fierce market competition and to courageously explore technological breakthroughs through persistent innovation. The Group is committed to leading the door, window and curtain wall industry into a new developmental phase, paving an ever-broadening path forward in the industry.
