Company patents

AIXTRON SE

AIXTRON SE's patent strategy is overwhelmingly concentrated in Coating & Surface Treatment, which accounts for 97.9% of its portfolio, yet this core area has seen a significant decline in patenting activity so far in 2026, dropping by 61.5% from 2025. This suggests a potential shift in focus, especially given the consistent decline in Semiconductor Manufacturing Process, which has seen a 100.0% drop in patent filings so far in 2026 compared to 2025.
