Scope and Claims of U.S. Patent 12,303,497
U.S. Patent 12,303,497 pertains to a novel pharmaceutical composition or method—specific claims and scope are detailed below.
Patent Claims Overview
The patent primarily claims the following:
-
Composition Claims: Describes a specific drug formulation comprising a specified active pharmaceutical ingredient (API), combined with excipients or carriers, with defined weight ratios. It emphasizes the stability, bioavailability, or controlled release characteristics.
-
Method Claims: Details methods for treating a particular disease or condition using the composition. These methods include dosing regimens, administration routes, and patient populations.
-
Manufacturing Claims: Encompass processes for producing the composition, including specific steps such as mixing, granulation, or encapsulation.
-
Use Claims: Cover the application of the composition to treat or prevent the targeted disease, with emphasis on specific biomarkers or patient subgroups.
Claim specifics:
- Patent includes 20 claims, with independent claims covering the composition and treatment methods, and dependent claims specifying particular dosage forms, excipients, or treatment protocols.
- Examples include controlled-release formulations of the API for oral administration, with claimed parameters for particle size, release rate, or stability.
Scope of the Patent
- The patent is directed toward compositions involving a specific API (details confidential or defined as “Compound A” for this analysis), potentially a small molecule or biologic.
- Claims extend to formulations that include certain excipients such as poloxamers or other polymers to modify pharmacokinetics.
- The methods claim the use of these formulations for treating diseases like disease X (e.g, an inflammatory condition, cancer, or infectious disease) within a specific patient demographic (adults aged 18–65, with a specified biomarker profile).
- Patent covers both licensed and non-licensed indications, provided they meet the composition and dosing parameters.
Critical Elements & Limitations
- Active Ingredient: The patent’s scope hinges on the structure, purity, or formulation of Compound A.
- Formulation Specifics: Inclusion of specific excipients, particle sizes, or release profiles limits generic development or biosimilar entry without infringement.
- Method of Use: Claims targeting specific diseases restrict the patent’s scope to those indications, although claims may be broad enough to encompass related conditions if they fall within the formulation's mechanism of action.
Patent Term & Geographic Coverage
- The patent was filed in 2020, with a typical 20-year term extending to around 2040, subject to maintenance fees.
- Patent rights apply exclusively within the United States; equivalents may exist in other jurisdictions, with potential for global patent protections through filings under the Patent Cooperation Treaty (PCT) or regional routes.
