Company patents

CAMBRICON TECHNOLOGIES CORPORATION LIMITED

CAMBRICON TECHNOLOGIES CORPORATION LIMITED's patent strategy reveals a surprising and consistent decline across its entire portfolio, including its core focus on Machine Learning & AI, which accounts for 84.5% of its patents but has seen a -33.3% YoY decline in 2025 and a -75.0% decline so far in 2026. This broad-based reduction, with categories like Operating Systems & Program Control and Multi-Chip & 3D Assemblies experiencing significant drops of -63.6% and -50.0% respectively in 2025, suggests a notable shift away from active patenting across its key computing and semiconductor interests.
