Octapeptide Patent Filed for Antibacterial
Summary
USPTO published patent application US20260109735A1 for an immunomodulatory octapeptide with broad-spectrum antibacterial activity, filed September 2, 2025 under Application No. 19317121. The application names Feiyun Yang, Jinxiu Huang, and Xiuliang Ding as inventors and covers the peptide's preparation method, purity testing, and applications in anti-bacterial and immunomodulation fields for animal husbandry. CPC classifications include C07K 7/64, A61P 31/04, C12P 21/02, G01N 33/6851, and A61K 38/00.
“The disclosure provides an immunomodulatory octapeptide, and this small peptide molecule has a unique structure, higher broad-spectrum antibacterial activity, stronger pathogenic bacteria inhibition and high purity, can maintain stability of its structure and antibacterial activity in artificial gastric juice, with no obvious hemolytic activity, and has high application value in animal husbandry.”
About this source
USPTO classification C07K covers peptides: short amino-acid chains that form the backbone of antibodies, hormones, vaccines, and increasingly a wider class of therapeutic modalities. Every newly published application in C07K lands in this feed, around 175 a month. Applications publish 18 months after filing, so this feed reveals what antibody engineering groups, vaccine developers, and plant biotech researchers were working on in the prior year and a half. Watch this if you compete in biologics, file freedom-to-operate analyses on antibody drug candidates, scout acquisition targets in vaccine platforms, or track protein-based agricultural biotech filings.
What changed
USPTO published patent application US20260109735A1 for an octapeptide composition, its method of preparation, and applications in anti-bacterial and immunomodulation. The application claims an immunomodulatory octapeptide characterized by unique structure, broad-spectrum antibacterial activity, pathogenic bacteria inhibition, stability in artificial gastric juice, and absence of hemolytic activity. The filing date is September 2, 2025, with Application No. 19317121.\n\nAffected parties include pharmaceutical companies, biotechnology researchers, and drug manufacturers working with peptide-based antibacterial agents. Competitors developing similar immunomodulatory peptides or antimicrobial compounds should review the application to assess potential patent landscape implications and freedom-to-operate considerations.
