Company patents
GUANGZHOU AUTOMOBILE GROUP CO., LTD.
GUANGZHOU AUTOMOBILE GROUP CO., LTD. shows a surprising, broad decline in patenting across nearly all categories in 2026 so far, with a 100% year-over-year drop in filings for key areas like Vehicle Control Systems (23.9% of portfolio), Electrical Measurement (12.7%), and Machine Learning & AI (8.5%), which had previously seen a 300% YoY growth in 2024. This suggests a significant shift in its patent strategy or a temporary pause in innovation output.
