Company patents

HANMI PHARM. CO., LTD.

HANMI PHARM. CO., LTD. demonstrates a clear focus on "Pharmaceutical Preparations," accounting for 87.5% of its portfolio, yet shows a surprising shift in its R&D priorities with a significant decline in patenting for "Therapeutic Activity (Pharma)" by -20.0% in 2025 and "Peptides & Proteins" by -40.0% so far in 2026, despite a strong rebound in "Peptides & Proteins" in 2025 with a +233.3% YoY growth. The company also appears to be exploring new avenues in "Polymer Synthesis (Polycondensation)," showing a 100.0% YoY growth so far in 2026, while largely divesting from "Material & Chemical Analysis," which saw a -100.0% decline in 2024 and so far in 2026.
