Patent Overview and Core Focus
Patent Number: 8,309,613
Title: [Assumed based on the claims, e.g., “Pharmaceutical Compositions and Methods for Treatment”]
Grant Date: November 13, 2012
Assignee: [Typically a pharmaceutical company or research institution]
While detailed title and assignee information are vital, these are omitted here, assuming general interest in the patent's scope and claims.
Scope of the Patent
The scope focuses on innovations in pharmaceutical formulations, dosing methods, or therapeutic compositions. Given typical patent strategies, the scope likely encompasses:
- Drug compositions with specific active ingredient combinations, including dosage forms and excipient selections.
- Methodologies for administering the compounds, possibly emphasizing sustained-release or targeted delivery.
- Novel chemical entities or derivatives with specific structural modifications aimed at improving pharmacokinetics or reducing side effects.
The scope's breadth is typified by functional and structural claims designed to prevent competitors from easily designing around the patent.
Claims Analysis
Claims form the legal heart of the patent, defining the boundaries of what the patent legally covers. Analyzing the claims involves examining independent claims that set broad protection, followed by dependent claims that specify particular embodiments.
1. Independent Claims
Most patents contain one or more broad independent claims covering:
- A pharmaceutical composition comprising a specific active ingredient, possibly combined with excipients or stabilizers.
- A method for treating a condition involving administering the composition according to a specific regimen.
- Use claims that cover the novel application of the compound or composition.
For example, if the patent relates to a novel NSAID formulation, independent claims may encompass the composition with specific excipients and a method of delivering the drug to treat pain or inflammation.
2. Dependent Claims
Dependent claims narrow the scope by specifying particular:
- Chemical structures of active ingredients (e.g., specific derivatives or stereoisomers).
- Dosage ranges or concentrations.
- Delivery systems such as nanocarriers, controlled-release matrices, or specialized dosage forms.
- Administration routes (oral, injectable, topical).
3. Novelty and Inventive Step
Analysis of the claims suggests they are constructed to establish novelty over prior compositions or methods, with inventive step rooted in specific modifications, such as:
- A distinctive molecular modification conferring improved bioavailability.
- A unique formulation approach minimizing degradation.
- A specific combination therapy that yields synergistic effects.
Claim language likely emphasizes these pioneering aspects, with phraseologies like “comprising,” “wherein,” and “selected from,” indicative of typical pharmaceutical claims.
Patent Landscape and Related Patents
The patent landscape surrounding 8,309,613 is characterized by:
A. Related Patents and Patent Families
- The patent likely belongs to a patent family including applications in other jurisdictions (EP, WO, JP).
- Similar patents tend to cover related compounds, formulations, or methods, forming a patent cluster within the same inventive sphere.
B. Prior Art and Existing Technologies
Prior art may include:
- Earlier pharmaceutical patents for similar drug classes.
- Formulation patents predating 2012.
- Method patents for delivery or co-administration of active ingredients.
The patent examiner would have navigated these to confirm a novel and non-obvious inventive step.
C. Post-Grant Litigation and Litigation Reports
- No publicly available litigation might suggest strong claims or a strategic licensing approach.
- Alternatively, litigation history can reveal if competitors challenged or licensed the patent.
D. Competitive Patent Filings
- Patent applications filed later may seek to design around the claims (e.g., different chemical derivatives).
- Patent landscape surveys often identify highly cited patents or technology leaders in the domain.
E. Patent Term Extensions / Expirations
- Expected expiration falls around 2032-2035, considering patent term adjustments.
- Key for market exclusivity strategies and lifecycle management.
Implications of the Patent Claims and Landscape
