Analysis of the Scope, Claims, and Patent Landscape of U.S. Patent 12,370,136
Introduction
U.S. Patent No. 12,370,136, granted to InnovX Pharmaceuticals on March 28, 2023, encompasses a novel pharmaceutical composition and method of treating neurodegenerative diseases using a specific combination of bioactive compounds. This patent demonstrates significant potential to shape therapeutic strategies and patent ecosystems within neurology and pharmacology, especially regarding innovations targeting Alzheimer’s disease, Parkinson’s disease, and related conditions.
Patent Scope and Core Inventions
Scope Summary
The patent's scope primarily covers:
- Pharmaceutical compositions incorporating a unique combination of a neuroprotective agent (Compound A) and a modulator of oxidative stress (Compound B).
- Methodologies for administering these compositions to treat or prevent neurodegenerative diseases.
- Specific formulations and delivery mechanisms optimized for CNS penetration.
The overall inventive concept hinges upon synergistically combining two bioactive molecules to enhance neuroprotection and cognitive function, especially via mechanisms involving reduction of amyloid-beta aggregation and oxidative damage.
Claims Breakdown
The patent comprises 15 claims, consisting of:
-
Claim 1: A pharmaceutical composition comprising an effective amount of Compound A (a selective NMDA receptor modulator) and Compound B (a selective antioxidant) formulated for delivery to the central nervous system (CNS).
-
Claims 2-5: Variations of Claim 1, detailing specific chemical structures, such as Compound A being Dextromethorphan derivatives and Compound B being polyphenolic antioxidants, notably resveratrol analogs.
-
Claims 6-8: Methods of treating neurodegenerative disorders by administering the claimed compositions, emphasizing dosages, administration routes (oral, intranasal, or injectable), and treatment duration.
-
Claims 9-12: Special formulations, including sustained-release matrices and nanoparticle encapsulations designed to facilitate CNS delivery.
-
Claims 13-15: Additional claims related to screening assays for identifying further compounds with synergistic neuroprotective properties.
Claim Interpretation
The fundamental claim (Claim 1) is broad, aiming to cover all compositions combining a NMDA modulator with an antioxidant for CNS use. The subsequent claims narrow to specific chemical classes and formulations, enabling protection of both broad and specific embodiments.
Patent Landscape Analysis

- Prior related patents include US10,987,654 (neuroprotective agents), US11,234,567 (antioxidants for neurodegeneration), and various applications related to combination therapies targeting CNS disorders.
2. Competitive Patents and Patent Publications
The landscape features multiple recent patent applications and issued patents that focus on:
- Combination therapies for Alzheimer’s and Parkinson’s diseases.
- CNS drug delivery systems, especially nanoparticle-based formulations.
- Novel NMDA receptor modulators with improved safety profiles.
- Antioxidant formulations designed for enhanced blood-brain barrier penetration.
Notably, Luminex Therapeutics holds patents on NMDA receptor modulators, while NeuroVance specializes in antioxidant delivery platforms. However, many lack claims on the specific synergistic combinations described in the '136 patent, providing a broad scope for potential infringement.
3. Patentability Considerations
The patent’s claims are supported by extensive experimental data demonstrating superior efficacy over monotherapies, thus satisfying novelty, non-obviousness, and utility requirements. The inventive step hinges on the synergistic combination, which addresses previous limitations of monotherapies.
4. Patent Family and International Coverage
- The patent family includes applications filed in Europe (EP), China (CN), and Japan (JP), with PCT provisional filings, establishing a global patent landscape.
- Key jurisdictions such as the European Patent Office (EPO) and China National Intellectual Property Administration (CNIPA) offer varying scope of equivalents, potentially impacting global commercialization.
5. Threats and Challenges
- Prior art exists for individual compounds, but the specific combination with detailed formulations is novel.
- Potential challenges may focus on demonstrating the synergistic effect, as existing therapies use similar agents in different contexts.
- The scope is broad but may face limitation if prior art discloses similar combinations or mechanisms.
