19.Patent Layout Comparison of Domestic and Foreign Concrete New Materials: Technological Breakthrough Path and International Promotion Strategy of Export-oriented Products

1. Current Patent Layout Pattern at Home and Abroad
In the field of high-end concrete new materials, foreign enterprises and scientific research institutions have formed a complete patent protection system. Europe, America and Japan have formed dense patent barriers in UHPC high-performance modification, microbial self-healing, carbon sequestration concrete and other high-end tracks, occupying the core technical patents and limiting the overseas promotion space of domestic technologies. In contrast, domestic patent layout is concentrated in the fields of solid waste resource utilization, low-cost green modification and civil engineering practical technology, with prominent application technical advantages but insufficient layout of original core patents.

2. Domestic Technological Advantages and Breakthrough Difficulties
Domestic concrete new material technologies have obvious characteristics of low cost, high practicability and strong engineering adaptability, and have accumulated a large number of applied patents in the fields of recycled aggregate concrete, industrial solid waste composite concrete and low-cost modified materials. However, due to the lack of original core patents in frontier functional materials, it is easy to face intellectual property disputes and technical barriers in the process of overseas promotion, which restricts the high-end export of domestic new material products and technologies.

3. Independent Technological Breakthrough Path
Aiming at overseas patent barriers, domestic enterprises should adopt differentiated patent layout and breakthrough strategies. Focus on the advantageous tracks of solid waste recycling and low-carbon localization modification, and carry out intensive patent layout of applied innovation and scene segmentation. Carry out innovative improvement and secondary development on the basis of foreign basic technologies to form differentiated independent patent clusters and avoid patent infringement risks. Build a patent protection system combining basic research patents and engineering application patents to form independent core technical barriers.

4. International Market Promotion Strategy
Establish an export promotion mode supported by independent patent technology. Take independent patent achievements as the technical endorsement of products, improve the international credibility and competitiveness of domestic new materials. Form a complete export system of 'patent technology + standardized products + engineering supporting services', carry out targeted market promotion for Southeast Asia, the Middle East and other emerging infrastructure markets, and gradually break the monopoly of foreign high-end building material technologies.

Conclusion

There are obvious differences and barrier characteristics in Chinese and foreign concrete new material patent layouts. Differentiated innovative patent layout and scene-based technological breakthroughs can effectively avoid intellectual property risks. Patent-backed product export strategies will help domestic green concrete new materials achieve breakthrough development in the global market.
