Company patents

SEAGEN INC.

Seagen Inc. exhibits a highly concentrated patent strategy, with 95.2% of its portfolio in Pharmaceutical Preparations and 67.3% in Peptides & Proteins, both showing significant declines in patenting activity since 2024 (e.g., Pharmaceutical Preparations decreased by 68.8% in 2025 and 75.0% so far in 2026). While Heterocyclic Compounds (Pharma) experienced a remarkable 600.0% YoY growth in 2024, it also saw a sharp decline in 2025, suggesting a potential shift away from these areas despite prior rapid expansion.
