Company patents
HANMI PHARM. CO., LTD.
HANMI PHARM. CO., LTD. demonstrates a highly concentrated patent strategy, with 87.5% of its portfolio in Pharmaceutical Preparations, yet shows a surprising shift in focus within its core pharma categories; while overall filings in Therapeutic Activity (Pharma) have declined by 20.0% in 2025, the company saw a significant resurgence in Peptides & Proteins with a 233.3% YoY growth in 2025 and an even more dramatic 250.0% YoY increase in Heterocyclic Compounds (Pharma) in the same year, indicating a targeted pivot towards specific chemical entities despite a general slowdown in broader pharmaceutical patenting.

Development and application of therapeutic proteins or peptides produced through recombinant DNA technology, including fusion proteins and modified growth factors.
Delivery systems specifically engineered to administer advanced drug formulations (e.g., microparticles, biologics, extended-release systems) to achieve precise targeting, controlled release kinetics, or enhanced therapeutic efficacy within the body.
Development of small molecules, often bifunctional (e.g., PROTACs) or molecular glues, that induce the ubiquitin-proteasome system or autophagy to selectively degrade specific disease-causing proteins.
Modification of protein or peptide sequences, structures, or post-translational modifications (e.g., glycosylation, lipidation) to enhance their stability, solubility, delivery, or therapeutic efficacy.
Design and synthesis of acyclic or carbocyclic organic compounds that selectively modulate specific biological targets or pathways for the treatment of diseases.
Design and engineering of proteins or peptides to directly modulate immune responses, including enhancing antigen presentation, suppressing inflammation, or activating specific immune cell types.
Therapeutic interventions that target immune checkpoint pathways to either enhance or suppress immune responses, often used in cancer immunotherapy or autoimmune diseases.
Methods and intermediates for preparing complex organic molecules intended as active pharmaceutical ingredients (APIs), often involving multi-step synthesis and optimization of reaction pathways.
Design and modification of antibodies or antibody-derived fragments for targeted therapeutic intervention, including bispecific formats, Fc region modifications, and activatable constructs.
Development of therapeutic approaches involving the genetic modification of cells (e.g., T cells, stem cells, macrophages) or the use of viral/non-viral vectors to deliver genetic material for disease treatment.
Therapeutic approaches involving the use of living cells, often genetically modified or ex vivo activated, to treat diseases, particularly cancer, by modulating immune responses or replacing damaged cells.
Methods and systems for the efficient and scalable production, purification, and formulation of proteins and peptides, including fermentation, chromatography, and cell-based expression systems.
Techniques for preparing and characterizing specific solid forms, such as crystal forms, salts, co-crystals, or amorphous forms, of active pharmaceutical ingredients to optimize properties like stability, solubility, and bioavailability.
Therapeutic strategies employing nucleic acids (DNA, RNA, oligonucleotides) to modulate gene expression, deliver genetic material, or interfere with disease-causing pathways. Includes gene therapy using viral vectors.
