The patent covers antibodies targeting human DLK-1, including CBA-1205, and combination therapy with lenvatinib; patents have already been granted in Japan, China, and Europe. The U.S. allowance is described as strengthening the company\u2019s intellectual property foundation supporting development and exploitation activities, and is stated to have no direct impact on the 2026 fiscal year performance. The plan remains to obtain safety and efficacy data from Phase 1 trials and pursue licensing to a pharmaceutical company.\n\n### Section 2 Heading\nDLK-1 is described as a factor that regulates proliferation and differentiation of immature cells, with potential as a target in hepatocellular carcinoma. With patent grants in Japan, China, and Europe, receiving U.S. patent allowance is a key element supporting the company's IP strategy and clinical development progress. However, the direct financial impact is considered limited, and longer-term value may depend on future clinical data and licensing outcomes.","jir_financial_highlights":"Impact period: Unknown (Unknown)","jir_category":"","jir_hashtags":"#environmental_ip, #new_drug_development_patents","jir_key_figures":"Patent Application US No. 17\/599,820\nNotice of patent allowance\nPhase 1 clinical trial of CBA-1205 domestically","jir_meta_title":"Chiome Bioscience Inc. \u2013 Notice of US Patent Allowance | September 25, 2026","jir_meta_description":"Notice of patent allowance for US rights covering the combination of humanized DLK-1 antibody CBA-1205 and lenvatinib.
