2.2 Novelty and Non-Obviousness
- The patent’s novelty hinges on:
- Specific lipid compositions optimized for neurological delivery.
- Integration of microfluidic processing steps specific to therapeutic lipid nanoparticles.
- Prior art such as US patents on lipid-based delivery systems for CNS (e.g., US Patent 9,682,787) contains similar compositions but lacks the microfluidic process or specific lipid ratios.
