Company patents
ESPRESSIF SYSTEMS (SHANGHAI) CO., LTD.
ESPRESSIF SYSTEMS (SHANGHAI) CO., LTD. shows a surprising shift in its patent strategy, moving away from its dominant Wireless Networks category, which accounts for 41.3% of its portfolio but saw a 50.0% decline in 2025 and so far in 2026. While System Reliability & Diagnostics experienced a rapid 200.0% growth in 2025, its complete absence so far in 2026 suggests a highly dynamic and potentially inconsistent focus on emerging areas.
