Patent Overview
CN102395401 is a Chinese patent filed for a novel pharmaceutical compound or formulation. The application was filed on [exact filing date if available], with a publication date [publication date], granted on [grant date]. Its core innovation involves [general description—e.g., the composition, method of preparation, or particular use], aimed at addressing unmet medical needs or improving existing therapeutic modalities.
Scope of the Patent
1. Subject Matter of the Patent
The patent primarily centers on:
- Chemical Composition: The novel compound or a specific combination of active pharmaceutical ingredients (APIs).
- Method of Manufacture: Innovative synthetic pathways or processing techniques enhancing yield, purity, or stability.
- Therapeutic Application: Specific medical indications, such as treatment of particular diseases or conditions.
- Formulation and Delivery: Novel formulations, including sustained-release systems or targeted delivery mechanisms.
This breadth allows the patent to encompass upstream synthesis, downstream formulation, and clinical application, effectively establishing wide protection over the inventive space.
2. Claims Structure
The patent comprises independent and dependent claims, with the former defining the broadest scope and the latter providing specific embodiments or optimizations.
- Independent Claims: These define the core invention, such as a new chemical entity with specified structural features or a novel use of a known compound in a therapeutic context.
- Dependent Claims: Detail specific variants, including particular substituents, dosage forms, or manufacturing conditions.
The claims are written to balance breadth—covering various embodiments—and specificity—to withstand validity challenges.
Analysis of Key Claims
1. Composition Claims
Claims encompass the composition of matter, usually employing chemical structures characterized by particular substituents, stereochemistry, or salt forms. For example:
- "A compound having the structure represented by formula I, wherein R1, R2, and R3 are defined as…"
These structure-based claims aim to cover not only the specific compound but also analogous derivatives within the scope.
2. Use Claims
Claims extend protection to therapeutic uses, such as:
- Method of treatment: Administering the compound to treat specific diseases, e.g., certain cancers, infectious diseases, or neurological disorders.
- New indications: Covering novel therapeutic applications beyond traditional uses.
