Company patents

Foghorn Therapeutics Inc.

Foghorn Therapeutics Inc. demonstrates a clear focus on core pharmaceutical innovation, with Heterocyclic Compounds (82.0% of portfolio) and Therapeutic Activity (62.3%) dominating its patent strategy. While these core areas have seen a decline in patent filings in 2024 and 2026 so far, the significant 166.7% year-over-year growth in Pharmaceutical Preparations in 2024, followed by a 25.0% growth in 2025, suggests a strategic shift towards protecting the formulation and delivery aspects of its therapeutic innovations, despite a partial decline in 2026.
