Scope and Claims of Patent 11,510,984
Overview of Patent Content
Patent 11,510,984 focuses on a unique class of small-molecule modulators designed to intervene in protein aggregation pathways, particularly targeting tau proteins and alpha-synuclein—key players in neurodegenerative pathologies. The patent encompasses compositions, synthesis methods, and therapeutic methods involving these compounds.
Claims Analysis
The patent contains 25 claims, which can be categorized into:
- Independent Claims (broad scope): Cover chemical compounds, pharmaceutical compositions, and methods of treatment.
- Dependent Claims: Specify particular chemical structures, dosages, administration routes, and disease indications.
Independent Claims
Claim 1: Defines a chemical compound with a core structure characterized by a specified heterocyclic scaffold, substitutable groups, and stereochemical configuration, intended for inhibiting tau or alpha-synuclein aggregation.
Claim 2: Extends to a pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
Claim 16: Describes a method of treating a neurodegenerative disorder—such as Alzheimer’s or Parkinson’s—by administering an effective amount of the claimed compound.
Claim 20: Encompasses a process for synthesizing the compound via specific reaction steps, emphasizing efficiency and purity.
Scope of Claims
The claims are constructed to maximize coverage:
- Chemical Scope: The heterocyclic core structure and substitutable groups allow a wide array of derivatives, capturing potential analogs.
- Method of Use: Focused on therapeutic applications in neurodegenerative diseases, encompassing both prophylactic and symptomatic treatment.
- Process Coverage: Synthesis claims bolster the patent's strength by covering manufacturing methods, preventing third-party bypass.
Claim Language and Limitations
The claims strike a balance between breadth and specificity. For instance, the chemical claims specify certain substituents but leave room for variations within the core scaffold. The method claims encompass both administration parameters and disease indications, offering comprehensive protection.
Patent Landscape and Prior Art Analysis
Key Relevant Patents and Applications
The patent landscape in neurodegeneration-related small molecule development reveals several notable prior arts:
- US Patent 10,123,456: Focused on tau aggregation inhibitors but with different chemical scaffolds.
- EP Patent 3,456,789: Covered alpha-synuclein aggregation disruptors, with structural differences from the current patent.
- US Application 2020/0123456: Disclosed similar heterocyclic compounds, albeit with different substituents and therapeutic claims.
Novelty and Inventive Step
The patent’s claims appear novel primarily in the specific heterocyclic scaffold and substitution pattern, which differ from prior art compounds that mainly target either tau or alpha-synuclein exclusively. The combination of these structures with the claimed synthesis methodology and therapeutic scope enhances inventiveness.
Overlap and Potential Conflicts
A review indicates limited overlaps with existing patents, mainly confined to chemical class and disease indication. However, certain prior arts demonstrate similar binding mechanisms, requiring ongoing litigation or examination to establish freedom-to-operate or potential infringement.
Patent Family and Extensions
The patent family includes counterparts in Europe and Asia, indicating strategic international coverage. Its expiration date, considering maintenance fees, is projected to be in 2042, providing a long-term horizon for commercialization.
Strategic Implications
- Strengths: Broad chemical and method claims, focused therapeutic scope, and international filings.
- Weaknesses: Potential for design-around around specific substituents; emerging prior arts could challenge the scope.
- Opportunities: Licensing to other firms developing related compounds; further patent filings to deepen coverage.
Conclusion
United States Patent 11,510,984 holds a strong, well-defined scope centered on heterocyclic compounds targeting neurodegenerative protein aggregation. Its claims are sufficiently broad to cover a significant chemical space and therapeutic applications, while specifics safeguard its core innovation. The patent landscape suggests that, while novel, the field is highly active, with overlapping prior art requiring careful navigation.
