Intellectual Property Rights

Our Patent Strategy
Our company strategy is to file patent applications and establish rights to all the core technologies used in our company's drug development business.
Our core drug development technologies cover the invention of substances (peptides, etc.), as well as methods (diagnostic and treatment modalities), and we aim to construct a network of patents covering both of these areas.

1. Invention of Substances (Peptides)
In our drug development business, diagnosis and treatment are two parts of one whole. Our peptides are indispensable both for diagnosis and treatment.
We are filing patent applications mainly in Japan, North America, and Europe for the candidate peptides found to induce a CTL response in research conducted at the Department of Immunology, Kurume University School of Medicine, during the past 10 years.

2. Invention of Diagnosis Methods
In our method of personalized therapy, immune diagnosis is utilized to select optimal peptides for personalized peptide vaccination before administering the peptide vaccine.
Therefore, the development of diagnostic methods is one of our company's most important business domains.
We have already filed a patent application for a diagnostic technology that is in an advanced stage of development.

3. Invention of Treatment Methods
Our method of treatment involves the administration of personalized peptide vaccines in which the selected peptides are chosen prior to the treatment on the basis of diagnostic tests. Therefore, the invention relative to our treatment methods is also an important focus of our company.
We have filed patents not only for peptides alone but also for combination treatments involving other medicines, based on the results of exploratory clinical research performed at the Kurume University School of Medicine.
