Company patents
HOLTEC INTERNATIONAL
HOLTEC INTERNATIONAL's patent strategy reveals a surprising recent shift, with significant activity in Welding & Soldering, accounting for 7.0% of its portfolio, seeing a sharp decline of -80.0% in 2025 and -100.0% so far in 2026 after a surge in 2024. Concurrently, while smaller in volume, the company shows an emerging interest in Photovoltaic (Solar Cells), maintaining its patent output in 2026 after an initial patent in 2025, suggesting a potential diversification into renewable energy, despite overall declines in other manufacturing-related categories like Heat Exchangers and Heat Exchange Components.
