LANMODULIN ORTHOLOGS WITH IMPROVED RARE EARTH SEPARATION PERFORMANCE
Summary
USPTO published patent application US20260098064A1 for lanmodulin orthologs (proteins) designed to bind rare earth metals with enhanced REE/REE selectivity. The application covers proteins with four EF hand motifs, methods of using the proteins, and devices/kits containing them. The invention has applications in rare earth element separation and processing.
What changed
USPTO published patent application US20260098064A1 for lanmodulin orthologs designed for rare earth metal binding. The proteins feature four EF hand motifs with 11-13 amino acid residues each, separated by 12-13 amino acid linkers, with enhanced REE/REE selectivity for separating different rare earth elements from each other.
For companies in mining, materials processing, or environmental remediation involving rare earth elements, this patent represents potential freedom-to-operate considerations. Entities developing or using rare earth separation technologies should review the patent claims to assess whether their processes or products may require licensing.
What to do next
- Monitor for patent issuance updates
- Review patent claims for potential infringement concerns

Abstract
Provided are proteins that bind rare earth metals. The proteins may have enhanced REE/REE selectivity. The proteins may have four EF hand motifs each having 11, 12, or 13 amino acids residues. Each EF hand motif is separated by 12 or 13 amino acid residues, where each amino acid residue is any canonical amino acid residue and at least one amino acid residue is a hydrophobic amino acid residue. When the EF hand motif has 12 amino acid residues, the motif may have the following sequence: X1-X2-X3-X4-X5-X6-X7-X8-X9-X10-X11-E. Also provided are devices and kits comprising a protein of the present disclosure. Also provided are methods of using the proteins and devices.
