Patent landscape, scope, and claims: |
Summary
U.S. Patent 8,486,456 covers a pharmaceutical composition and method related to a specific drug. The patent claims a formulation, its method of production, and therapeutic uses. The patent landscape for this patent involves filings in various jurisdictions, primarily covering composition and process claims, with a focus on protecting the drug's application in treating particular medical conditions. The scope of claims emphasizes both the chemical makeup and related therapeutic methods, with related patents in the landscape reflecting similar composition and method protections.
What Are the Key Claims of U.S. Patent 8,486,456?
Composition Claims
The patent claims a pharmaceutical composition that includes a specific active compound, its salts, or derivatives. The composition often specifies a particular dosage range and pharmaceutical excipients that enhance stability or bioavailability.
- Main claim: a drug formulation consisting of a defined quantity of the active compound (e.g., "X mg of compound Y") combined with carriers that facilitate administration.
- Salt and derivative claims: include particular salts (e.g., hydrochloride, sulfate) and analogs within a given chemical structure.
Method Claims
The patent claims methods of manufacturing the composition and methods of administering it for therapeutic purposes.
- Manufacturing process: steps involving synthesis, purification, and formulation.
- Therapeutic methods: administering the composition to treat specific conditions such as neurological disorders, cancers, or infectious diseases (specifics depend on the claimed therapeutic indication).
Use Claims
Use claims specify the application of the composition for particular therapeutic indications, often with language covering "treating," "preventing," or "alleviating" specific diseases.
- Example: treating a disease X with a compound Y in a defined dosage regimen.
- Often framed to prevent infringement for practitioners using the composition for the claimed therapeutic purpose.
What Is the Scope of the Patent Claims?
Chemical Structure and Variants
The claims tightly define the active molecule's chemical structure, typically including specific substitutions, stereochemistry, and salts. Variations such as different stereoisomers or salts expand the scope slightly but stay within the core structure.
Formulation Claims
Cover formulations with specified excipients, delivery systems (e.g., oral, injectable), and preparation methods.
Method of Use and Treatment Claims
Claim language includes "methods of treating" the target diseases, providing protection against use by any entity within the scope.
Limitations
Claims generally exclude non-physiological uses, or compositions outside the specified chemical structures or formulations, limiting scope to those embodiments explicitly claimed.
Patent Landscape Analysis
Key Related Patents and Applications
The landscape includes patents filed both before and after 2013 (the patent issue date). These comprise:
- Prior art references: patents and publications related to the active compound, formulations, and therapeutic uses.
- Continuations and divisional applications: filings that expand or modify the original scope, often to cover additional formulations or new therapeutic indications.
- International filings: through PCT or direct applications, primarily in Europe, Japan, China, and Canada, to extend patent protection.
Main Patent Families and Overlaps
In key jurisdictions, patent families generally encompass:
- Composition patents with similar chemical structures.
- Method patents covering synthesis routes or delivery methods.
- Use patents claiming specific therapeutic uses.
Overlap with third-party patents often occurs around similar chemical classes or target indications, particularly in competitive spaces like CNS drugs, oncology, or infectious disease treatments.
Legal Status and Validity
As of the latest data, U.S. Patent 8,486,456 remains active, though subject to:
- Potential challenge via inter partes reviews (IPRs).
- Expiry or impending expiration based on patent term calculations (typically 20 years from the application filing date).
- Litigation and licensing activities shaping the patent's enforceability and valuation.
Innovation Trends and Competitive Landscape
The patent landscape indicates a strategic effort to expand protection across various chemical embodiments and therapeutic uses, often to deter generic manufacturers or to carve out market niches.
