Amino acid-modified lipids enable RNA delivery via lipid nanoparticles

USPTO published patent application US20260091126A1 claiming amino acid-modified lipids for forming lipid nanoparticles (LNPs) that deliver therapeutic RNA molecules including siRNA, mRNA, miRNA, shRNA, and oligonucleotides. The application covers 15 CPC classifications spanning pharmaceutical compositions (A61K 47/6929), peptide chemistry (C07K 5/ series), and nucleic acid delivery systems (C12N 15/88). The inventors demonstrate utility for silencing oncogene overexpression.\n\nPatent applicants and researchers developing LNP-based RNA therapeutics should review the claimed lipid modifications and delivery compositions for potential licensing opportunities or to assess freedom-to-operate. Pharmaceutical companies and biotechnology firms working on gene silencing, mRNA vaccines, or cancer therapeutics may find relevant claims. No immediate compliance action is required as this is a patent publication rather than an enforceable regulation.
