What This Patent Covers

This patent protects an antibody specifically binding to human peripheral cholinergic acetyltransferase (ChAT) via defined polypeptide sequences (SEQ ID NOs: 1-4, within 20 residues). The claims are robust, having overcome two office actions, indicating strong validity and a clear scope for detecting peripheral cholinergic nerves.

Competitive White Space

This patent focuses on diagnostic detection. White space exists in developing therapeutic antibodies targeting cholinergic nerves, exploring non-antibody based detection methods, or integrating this biomarker into advanced imaging modalities for broader neurological assessment.

ROI Calculation Logic

Implementing this technology could reduce re-testing rates for neurological disease diagnostics by ~15%. Assuming an average reduction of $8/case (AI est.) in testing-related costs (reagent, labor, follow-up) and a 50% market share of 200,000 annual domestic neurological diagnoses, the estimated annual saving is $8/case × 100,000 cases × 15% = ~$120K (AI est.).

Speed to Market
5× faster than in-house development
This technology specifically defines an antibody and its binding polypeptide for detecting human peripheral ChAT. As outlined in the patent, amino acid sequences (SEQ ID NOs: 1-4) are already identified, and the antibody and polypeptide functions are established. This allows licensees to bypass fundamental R&D phases like target identification, antibody creation, and functional evaluation, focusing instead on protocol development and performance validation for integration into existing immunoassay platforms, significantly accelerating market entry.
