To promote the layout of standard essential patents in China's aviation industry and enhance the integration of patents and standards in the high-end equipment manufacturing sector, this paper takes enterprises in the aviation industry chain as the research perspective to conduct patent retrieval and statistical analysis based on patent databases and industry standards repositories. The results show that patents within the aviation industry chain are insufficiently integrated with international standards, and their industrial adaptability remains weak，with room for improvement in quantity, track selection, mechanisms, operation and maintenance, and synergy. Based on the above analysis results and the domestic policy environment, application strategies and layout paths for standard essential patents are proposed. It is pointed out that efforts should focus on niche tracks with strong interoperability and that a multi-party collaborative whole-chain working mechanism should be established. This research can provide a reference for promoting the deep integration of patents and standards in the aviation industry and for high-end equipment manufacturing industry groups to carry out relevant domestic business.
