The EPO published patent EP4110927A1, claiming recombinant microalgae engineered to express collagen, elastin, and related polypeptide sequences within chloroplasts. The patent, filed by applicant Alganelle (inventor Tissot-Lecuelle), covers the genetic constructs, transformation methods, and resulting peptide products. The application was classified under C12N 15/82 and designates all EPC contracting states.

This patent publication does not impose compliance obligations on third parties. Biotech companies developing microalgae-based protein expression systems should conduct freedom-to-operate analyses to assess potential infringement risks. Licensing opportunities may exist for entities seeking to utilize this chloroplast-based production technology.
