Abstract: This paper analyzes the development status of Tianjin's large model industry from a patent perspective,identifies existing issues,and proposes targeted solutions based on a problem-oriented approach. The analysis reveals that while Tianjin has made progress in technological innovation,industrial chain layout,and talent cultivation,significant gaps remain in patent portfolio strategies,technological innovation capabilities,and industrial concentration. To address these challenges,suggestions such as strengthening policy guidance,improving the talent cultivation system,and optimizing industrial chain coordination are put forward to promote sustainable development of Tianjin's large model industry.

Key words: large model industry, invention patent, countermeasures and suggestions
