Company patents

PanelSemi Corporation

PanelSemi Corporation's patent strategy shows a strong, sustained focus on core semiconductor technologies, with Multi-Chip & 3D Assemblies (29.2% of portfolio) and Printed Circuits & Electronic Assemblies (27.1%) leading their portfolio, both experiencing significant growth in 2024 (YoY +66.7% and +200.0% respectively). A surprising emerging focus is seen in Antennas, which, despite representing 18.8% of the portfolio, saw a remarkable 400.0% year-over-year growth in 2025, indicating a potential strategic diversification beyond their primary semiconductor and display interests, though patenting activity across most categories has seen a sharp decline so far in 2026.
