Phosphate-containing copolymers for virulence suppression
Summary
The European Patent Office published patent application EP4182377A1 for 3M Innovative Properties Company's phosphate-containing copolymers designed to suppress bacterial virulence. The invention covers copolymer compositions targeting A61P 31/04 (anti-infectives). Designated states cover all EU member states plus additional European countries.
What changed
The EPO published patent application EP4182377A1 disclosing phosphate-containing copolymers for virulence suppression in bacterial infections. The copolymers (classified under C08G 65/335 and A61K 31/765) are designed to inhibit bacterial virulence factors. Inventors include Carl Laskowski, Timothy Gillard, Ranjani Parthasarathy, Hannah Cohen, and Max Kruziki.
Pharmaceutical and biotechnology companies developing anti-infective therapeutics should consider this patent when designing programs targeting bacterial virulence pathways. The designated state coverage (all EU member states plus Switzerland, Norway, and others) means any commercial development of similar phosphate copolymer compositions in Europe may require licensing negotiations with 3M.
What to do next
- Monitor for competing patent applications in virulence suppression space
- Review Freedom to Operate if developing anti-bacterial copolymers
