Company patents
Wuhan Tianma Micro-Electronics Co., Ltd.
Wuhan Tianma Micro-Electronics Co., Ltd. shows a surprising, albeit small, focus on Heterocyclic Compounds (Pharma), accounting for 5.1% of its portfolio, which seems unrelated to its core display and semiconductor business. While its primary Display Drivers category remains dominant at 49.8%, the company is rapidly shifting priorities away from Integrated Circuit Layout & Arrangement, which saw a dramatic 71.4% decline in 2025 and no patents so far in 2026, and Specialty Semiconductor Devices (Legacy), which completely ceased patenting in 2025.
