USPTO Patent Applications - Peptides (C07K)
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.
