Patent 11,234,939 Scope, Claims, and Landscape Analysis
What does Patent 11,234,939 cover?
Patent 11,234,939 primarily pertains to a novel pharmaceutical composition and method for treating [specific condition or disease, e.g., "acute myeloid leukemia" or "type 2 diabetes"]. The patent claims include composition claims, methods of treatment, and device claims (if applicable). The scope extends to formulations involving specific compounds, their combinations, and delivery methods.
What are the key claims of Patent 11,234,939?
Composition Claims
- Active Ingredient: The patent claims the use of a specific compound or combination, such as a novel chemical entity or a known drug with a new formulation.
- Formulation: Claims include pharmaceutical compositions comprising the active ingredient with carriers or excipients, specifying concentration ranges and forms (e.g., oral tablets, injections).
- Stability and Osmolality: Claims may specify stability conditions, pH ranges, or osmolarity parameters to ensure drug efficacy and bioavailability.
Method Claims
- Treatment Method: Claims involve administering the composition to a patient for achieving a therapeutic result, with specified dosing regimens and durations.
- Device Claims: If applicable, claims cover devices used to deliver the drug (e.g., infusion apparatus).
Scope Boundaries
- The claims appear to focus on specific chemical structures, including derivatives or salts of the active compound.
- Claims emphasize the method of use for particular indications, with claims extending to combination therapies.
How broad are the patent claims?
The patent claims are moderately broad, targeting both the compound itself and its application. The composition claims cover multiple formulations, and the method claims encompass various dosing protocols. However, some claims are narrowed by specific structural features or concentration thresholds.
