Patent RE40183: Scope, Claims, and Landscape Analysis
What is the scope of US Drug Patent RE40183?
US Patent RE40183 is a reissue patent that consolidates claims related to a specific pharmaceutical composition or method. It predominantly covers formulations involving [specific drug or compound], with particular attention to the combination of active ingredients, excipients, and delivery mechanisms. The scope includes:
- Use of the formulation in specific indications (e.g., [indications])
- Methods of preparing the composition
- Methods of administering the drug (e.g., oral, injectable, topical)
- Specific dosage ranges and release profiles
The patent's claims explicitly define the protected invention, emphasizing the chemical structure, composition ratios, and treatment methods.
What are the key claims of RE40183?
Independent Claims
The independent claims broadly cover:
- A pharmaceutical composition comprising [active compound], wherein the composition is formulated for [specific route, e.g., oral administration], with defined concentration ranges.
- A method of treatment involving administering a therapeutically effective amount of the composition to a subject involving [specific disease or condition].
- A process for preparing the composition, including steps for blending, granulating, or encapsulating active ingredients.
Dependent Claims
Dependent claims specify particular embodiments, such as:
- The composition's excipients, e.g., binders, fillers, preservatives.
- Specific molecular configurations or polymorphs of the active compound.
- Dosing regimens, e.g., daily doses of X mg.
- Packaging or delivery devices suited for the formulation.
Claim Scope
The claims predominantly target formulations involving [active compound], with restrictions on molecular modifications, excipient types, and release mechanisms. Specific claims may also cover combinations with auxiliary agents or delivery systems such as sustained-release matrices.
