Company patents
Hong Kong Applied Science and Technology Research Institute Company Limited
Hong Kong Applied Science and Technology Research Institute Company Limited exhibits a strong and sustained focus on Computer Vision, which saw remarkable 200.0% year-over-year growth in both 2024 and 2025, now representing 15.2% of its portfolio. While computing-related categories like Image Processing (19.6% of portfolio) remain central, the significant year-over-year declines so far in 2026 across multiple categories, including Machine Learning & AI (-100.0%), Material & Chemical Analysis (-100.0%), and Optical Elements & Systems (-100.0%), suggest a potential strategic shift or a reallocation of R&D resources, though 2026 data is partial.
