The rapid advancement of artificial intelligence technology makes it crucial to understand its global development trends for technological innovation and industrial planning. Utilizing global AI patent data, this study performs a quantitative analysis across three dimensions: macro-trends, frontier research directions, and emerging application scenarios. Findings indicate that global AI patenting entered a phase of exponential growth in 2013; while China leads in total patent volume, the United States maintains a competitive edge in high-barrier vertical domains. Currently, algorithm optimization, model lightweighting, and multimodal fusion constitute the primary technological frontiers. Furthermore, application scenarios such as the Metaverse, the low-altitude economy, and green/low-carbon initiatives have gained significant momentum recently. Research indicates that global AI innovation is transitioning from scale expansion to efficiency optimization and scenario-driven development.
