Company patents
Shanghai Tianma Micro-Electronics Co., Ltd.
Shanghai Tianma Micro-Electronics Co., Ltd. shows a surprising shift in its patent strategy, with a significant decline in its traditionally strong Display Drivers category (25.8% of portfolio), which saw a -75.8% YoY drop in 2026 so far, alongside a notable decrease in Integrated Circuit Layout & Arrangement (-100.0% YoY in 2026). However, the company is demonstrating an emerging focus on Organic Electronics (OLED), which experienced a substantial 108.3% YoY growth in 2024, indicating a strategic pivot towards advanced display technologies despite a recent dip in 2025.
