On November 11, Yu Hanzheng, Director of the Quality Assurance Division of the Mechanical Invention Examination Department of the Patent Office under the China National Intellectual Property Administration, introduced the "1+N" collaborative examination quality management system in the mechanical field: with the Mechanical Invention Examination Department as the lead body and the mechanical field departments of the various examination cooperation centers as the executing bodies, emerging industries such as additive manufacturing are included in the scope of key protection. This mechanism accelerates patent examination and protection for core technologies in additive manufacturing equipment, materials, and processes through unified examination standards and quality management; a shortened grant cycle helps leading companies build patent barriers more quickly and reduces innovation uncertainty. The acceleration of patent grants in the additive manufacturing field is in step with the deep development of China's 3D printing industry from equipment toward materials and processes, and the simultaneous rise in patent quality and quantity will become a key competitive asset for domestic manufacturers. Value for buyers: equipment and powder purchasers can track the patent trends of leading manufacturers as a reference for equipment selection, process benchmarking, and patent risk screening.
