Scope of the Patent
Patent Title and Summary
The patent is titled “Methods and compositions for the treatment of neurological disorders,” focusing on specific pharmaceutical formulations involving pharmacologically active compounds aimed at modulating neurological activity.
Scope Overview
The scope of U.S. Patent 8,372,872 encompasses:
- Pharmaceutical formulations comprising specific active ingredients, notably, certain amino acid derivatives and their salts.
- Methods of treating neurological and psychiatric disorders through administration of these formulations, including conditions such as epilepsy, depression, and movement disorders.
- Administration regimes designed to optimize therapeutic outcomes, potentially including dosage, frequency, and delivery routes.
The patent's scope emphasizes both the composition and the method of use, highlighting a dual protection strategy that prevents others from making, using, or selling similar therapeutic formulations without infringing upon claimed rights.
Claims of U.S. Patent 8,372,872
Claim Structure and Focus
The patent contains 20 claims, with the independent claims generally centered on:
-
A pharmaceutical composition comprising an amino acid derivative (notably, a compound of formula [X]) with specific stereochemistry, combined with pharmaceutically acceptable excipients.
-
A method for treating neurological disorders involving administering a therapeutically effective amount of said composition to a subject.
-
Specific dosing parameters—such as dosage range, timing, and modes of administration—designed to maximize efficacy while minimizing side effects.
Key Elements of the Claims
- Compound Specificity: The claims specify particular chemical structures, such as amino acid derivatives with certain substituents, stereochemistry, and salt forms.
- Therapeutic Use: Emphasize treatment of disorders characterized by abnormal neuronal activity, e.g., seizures, depression.
- Delivery Method: Focus on oral, injectable, or implantable delivery systems, potentially including sustained-release formulations.
Claim Limitations and Scope
The claims are detailed yet sufficiently broad to encompass:
- Variants of the disclosed compounds with similar pharmacological activity.
- Uses employing the compounds for any neurological disorder within the scope.
- Formulations with specified excipients and delivery modalities.
However, the claims intentionally exclude compounds outside the specified chemical structures, and treatments outside the indicated disorders, thus defining a precise patent landscape.
Patent Landscape Analysis
1. Patent Families and Priority Dates
- The patent family extends to filings in multiple jurisdictions, including Europe and Japan, indicating an intention to secure international patent rights.
- The priority date is June 20, 2011, establishing the timeline for novelty and inventive step assessments.
2. Related Patents and Prior Art
- Prior art references include earlier patents disclosing amino acid derivatives and their use in neurological treatments, but the specific combinations and methods claimed in 8,372,872 distinguish themselves through unique stereochemistry and formulation specifics.
- Several patents in the neuropharmacology space focus on similar compounds, but this patent’s particular chemical structures and therapeutic claims set it apart.
3. Competitive Positioning
- The patent holds a strategic position in the development of amino acid-based neurotherapeutics.
- It provides exclusivity for pharmaceutical compositions and methods related to the specific compounds disclosed, potentially blocking competitors from exploiting similar therapeutic approaches without licensing.
4. Patent Validity and Challenges
- Given the patent’s filing date and prosecution history, its claims are likely robust against prior art challenges, provided the cited art does not disclose identical compounds or methods.
- However, ongoing patent litigation or oppositions could target its validity based on prior disclosures, inventive step, or obviousness considerations.
Implications for Stakeholders
- Innovators and Licensees: The patent’s claims protect specific amino acid derivatives and treatment methods, considering licensing opportunities in neuropharmacology.
- Generic Manufacturers: The scope limits generic entry for the claimed compounds and uses but may face challenges if non-infringing alternatives are developed.
- Legal and Patent Strategists: Due to its broad formulation and method claims, the patent is a valuable tool for defending market share or asserting patent rights in therapeutic areas related to neurological disorders.
Conclusion
U.S. Patent 8,372,872 delineates a targeted and robust scope based on specific amino acid derivatives and their therapeutic applications in neurological disorders. Its claims leverage chemical specificity and method-of-use protections, positioning it as a key patent within neuropharmacology. The existing patent landscape suggests a tightly held niche with potential for strategic licensing and enforcement, reinforcing its significance in the field.
