SQZ Biotechnologies Cell Delivery Patent - EP3728559A1
Summary
The European Patent Office granted Patent EP3728559A1 to SQZ Biotechnologies Company on April 1, 2026, covering a system for delivering payloads into cells through membrane disruption. The patent names inventors Dadgar, Abdeljawad, and Bernstein and covers 31 designated European states including major markets.
What changed
The EPO published Patent EP3728559A1 granting SQZ Biotechnologies exclusive rights to a cell delivery system that uses mechanical membrane disruption to transport payloads directly into cell cytoplasm. The system represents an alternative to viral vectors and lipid nanoparticles for intracellular delivery.\n\nPharmaceutical and biotech companies developing cell therapies, gene editing tools, or intracellular drug delivery should monitor this IP position. Competitors working on similar delivery technologies may need to design around this patent or seek licenses. The patent applies across all 31 designated EPO member states, providing broad geographic protection in Europe.
What to do next
- Monitor patent register for potential licensing opportunities
- Review intracellular delivery methods for Freedom to Operate implications
- Assess IP landscape for competing cell delivery technologies
