Company patents
BAIDU ONLINE NETWORK TECHNOLOGY (BEIJING) CO., LTD.
BAIDU ONLINE NETWORK TECHNOLOGY (BEIJING) CO., LTD. shows a surprising and significant decline across nearly its entire patent portfolio, with core areas like Databases & Information Retrieval (37.3% of portfolio) experiencing a -69.7% YoY drop in 2024 and -40.0% in 2025, and Machine Learning & AI (17.9% of portfolio) plummeting by -50.0% in 2024 and -57.1% in 2025. This widespread and consistent reduction, with many categories showing zero patents so far in 2026, suggests a dramatic shift away from patenting in these previously strong computing and AI domains.
