The opening ceremony of the Hong Kong-Zhuhai-Macao Bridge was held on the morning of October 23 in Zhuhai City, Guangdong Province. General Secretary of the CPC Central Committee, President of the State, and Chairman of the Central Military Commission Xi Jinping attended the ceremony and announced that the bridge was officially opened.
The Hong Kong-Zhuhai-Macao Bridge lasted for 14 years from design to completion. It is the largest cross-sea bridge in the world's architectural history with the longest mileage, the most investment, the most difficult construction and the largest project scale. The design life of the bridge is 120 years. It can withstand the magnitude 8 earthquake and the 16-level typhoon. The foreigners once thought it was impossible to complete the task. It was named one of the "Seven Wonders of the New World" by the British "Guardian". The “joint” of this “steel dragon” – 97% of the bridge expansion joint is designed, manufactured, and installed by Ningbo Roaby Technology Industrial Group Co., Ltd. The patented technology comes from Bin Xu, the founder of the company. In order to meet the stringent technical requirements and application environment of the Hong Kong-Zhuhai-Macao Bridge, Roaby has designed a multi-directional displacement telescopic device to enable three-dimensional displacement. At the same time, its world-first environmental noise reduction technology meets high-level performance requirements such as noise reduction and seismic resistance. CCTV also reported on the important role of the “Expansion Joint” to the Hong Kong-Zhuhai-Macao Bridge.
In 2009, Bin Xu’s invention patent for “A Very Large Flexibility Distortion Resist and Comb-Type Bridge Expansion Joint” (ZL200410049491.5) won the highest government department award in China's patent field – the China Patent Gold Award. In 2015, it won the highest award from the World Intellectual Property Organization - "Best Invention Award". The patented technology has broken the monopoly of foreign industry giants for bridge expansion joint for more than 100 years, which has reduced the construction cost of expansion joints by more than 33% and reduced operating costs by 80%.
Previously, this product has been successfully applied to Hangzhou Bay Bridge, Guangzhou Zhujiang Huangpu Bridge, Shanghai Zhapu Bridge, Jiujiang Yangtze River Bridge, Chongqing Changshou Yangtze River Bridge and other large bridges, as well as in several highways. It has saved the country a huge amount in engineering cost.
In recent years, the infringement lawsuit surrounding the patent has never been interrupted. Roaby Group attaches great importance to its intellectual property protection and always actively defends its rights. At the beginning of this year, Sunshine IP International was entrusted by the patentee to represent the patent invalidation request involving the invention patent. After detailed investigation and evidence collection, a strict response strategy was elaborated against the invalidation. Recently, the Patent Reexamination Board passed the trial and made an invalidation request review decision to maintain the patent right of the invention.
