This report offers a comprehensive analysis of the patent’s scope, claims, and its positioning within the broader patent landscape, providing strategic insights for industry stakeholders.
Scope of Patent 9,241,935
Patent Classification and Background
The '935 patent primarily falls within classes related to pharmaceutical compositions and methods of treatment. Its scope appears centered around a novel combination, formulation, or method involving a therapeutic agent—potentially targeting a specific disease or condition with improved efficacy or reduced Side effects. The patent’s claims delineate the boundaries of the invention, intending to protect novel aspects that distinguish it from prior art.
Core Innovation
While the exact claims require detailed review, the patent's scope suggests an inventive step related to:
- A specific chemical entity or class.
- A unique formulation (e.g., controlled-release, stereoisomers).
- A novel method of administration.
- An improved therapeutic indication with enhanced safety or efficacy.
By defining these parameters, the patent aims to prevent third-party competitors from copying the inventive features, securing market exclusivity.
Claims Analysis
Claims Overview
The patent contains multiple claims, generally categorized as:
- Independent Claims: Broad claims that establish the core invention.
- Dependent Claims: Specific embodiments or features that narrow the scope.
Key Independent Claims
The primary independent claims likely cover:
- A pharmaceutical composition comprising a specific chemical compound or combination.
- A method of treating a disease state using the claimed composition.
- Composition formulations with particular ratios, delivery systems, or physical characteristics.
Dependent Claims
Dependent claims often clarify:
- Preferred embodiments (e.g., specific dosages, routes of administration).
- Variations in formulation (e.g., salts, hydrates).
- Specific patient populations or indications.
Claim Language and Limitations
The precision of claim language influences enforceability. For example:
- Use of open language ("comprising") permits inclusion of additional components.
- Narrow claims specify exact chemical structures or process steps.
Given the patent’s classification, claims may aim to balance breadth—covering broad therapeutic classes—while maintaining defensibility against prior art.
Claim Scope and Strategic Implications
- Broad claims enhance market exclusivity but invite challenges from prior art.
- Narrow claims reduce litigation risk but limit scope.
- The patent’s strategic strength depends on how well its claims withstand validity challenges and infringing parties.
Patent Landscape Context
Overlap with Prior Art
The patent's scope overlaps with previous patents and publications in:
- Similar chemical compounds.
- Alternative formulations.
- Existing methods of treatment.
The novelty appears rooted in specific features, such as a particular stereoisomer, formulation, or combination therapy, which distinguish it from prior art.
Related Patents and Applications
The landscape includes:
- Family patents covering analogous compounds or methods.
- Patent applications filed before and after the '935 patent, indicating ongoing innovation efforts.
- Patent interferences or litigations, depending on contested claims.
