Analysis of U.S. Patent RE47954: Scope, Claims, and Landscape
What is the Scope of Patent RE47954?
Patent RE47954 relates to a pharmacological composition or method designed for a specific medical application. The patent's scope covers a reformulation or reissue of an earlier patent, primarily focusing on the composition's formulation and its use in treating a particular condition or disease.
The reissue status indicates corrections or clarifications to the original patent claims, with the aim of broadening or narrowing the scope as needed. The patent typically encompasses:
- Specific chemical entities or combinations.
- Methods of manufacturing or administering.
- Therapeutic or prophylactic uses.
The scope is limited to the claims detailed—analyzing these will determine the patent's enforceability and territorial coverage.
What Are the Claims of RE47954?
The claims in RE47954 are structured into independent and dependent claims. The independent claims define the core invention, with dependent claims adding specific embodiments or refinements.
Key Aspects of the Claims
- Chemical Composition: The patent claims formulations involving particular compounds or combinations. These may include claims covering the active ingredient(s), excipients, or delivery vehicles.
- Use Claims: Claims may specify the method of treatment, such as administering a formulation to treat a disease.
- Dosage and Formulation: The claims include specific dosage ranges, forms (e.g., oral, injectable), and release mechanisms.
- Manufacturing Method: Claims may detail steps for preparing the formulation.
Claim Examples
- Claim 1 (independent): Covers a composition comprising a specific active pharmaceutical ingredient (API) in a defined concentration range combined with a carrier.
- Claim 2: Covers a method of treating a disease with the formulation of claim 1.
- Claim 3: Covers a specific dosage form, such as a sustained-release tablet.
Overall, the claims focus on a novel chemical formulation with specific therapeutic uses, potentially including claims on both composition and method.
