Company patents

Halozyme, Inc.

Halozyme, Inc. surprisingly shows a significant, albeit fluctuating, focus on "Peptides & Proteins" (48.0% of portfolio) and "Material & Chemical Analysis" (46.7%), both of which saw explosive growth in 2024 (YoY +2100.0% and +400.0% respectively) before sharp declines in 2025 and so far in 2026, suggesting a dynamic but potentially volatile R&D pipeline beyond its core "Pharmaceutical Preparations" (85.3% of portfolio) which also saw a 38.5% decline in 2025.
