Company patents
HEFEI XINSHENG OPTOELECTRONICS TECHNOLOGY CO., LTD.
HEFEI XINSHENG OPTOELECTRONICS TECHNOLOGY CO., LTD. appears to be significantly shifting its patent strategy, with a notable decline across most categories in 2025 and so far in 2026, following a surge in 2024, particularly in Organic Electronics (OLED) which saw a +213.3% YoY growth in 2024 before a -51.1% decline in 2025. This suggests a potential re-evaluation of R&D focus, moving away from areas like Integrated Circuit Layout & Arrangement, which has seen a -100.0% decline in 2026 after an -80.0% decline in 2025.
