Company patents
Picosun Oy
Picosun Oy's patent strategy is heavily concentrated in "Coating & Surface Treatment," which accounts for 95.6% of its portfolio, yet this core area has seen a consistent decline in new patents, with a -14.3% YoY drop in 2025 and a sharp -83.3% decline so far in 2026. While the company showed an emerging focus in "Semiconductor Manufacturing Process" with a +200.0% YoY growth in 2025, and a prior surge in "Implants & Prosthetics" (+50.0% YoY in 2024), these areas, along with "Electron / Ion Tubes & Discharge," appear to be shifting priorities with no new patents so far in 2026.
