Scope of Patent Claims
1. Types of Claims:
CN116096423 comprises independent claims that define the core innovation and dependent claims that specify particular embodiments, modifications, or specific uses. The scope primarily hinges on:
- The chemical structure or molecular formula of the drug.
- The method of synthesis or production process.
- The pharmacological application or therapeutic method.
- The drug delivery system or formulation parameters.
2. Independent Claims:
-
Core Compound or Composition: The main claim likely covers a novel chemical entity or a pharmaceutical composition comprising a specified drug molecule, marked by unique structural features conferring particular therapeutic efficacy.
-
Method of Use: Claims may also encompass a method for treating a disease or condition, characterized by administering the compound or composition.
-
Manufacturing Process: If inventive, claims could also include the process for synthesizing the drug, emphasizing efficiency or yield improvements.
3. Scope of Claims:
-
The breadth of the independent claims indicates a broad protective scope, potentially covering not only the specific compound but also analogs with similar structural motifs.
-
The specificity of dependent claims further delineates narrow embodiments, such as specific dosage forms, combinations, or administration routes, which supports enforcement against infringing variants.
-
Claim Limitations: The claims likely specify the chemical substituents or functional groups essential for the activity, establishing the boundaries of patent protection.
4. Claim Language and Patentability Factors:
-
Use of precise chemical nomenclature enhances the clarity and enforceability of the claims.
-
Claims appear crafted to balance breadth with novelty, focusing on inventive features over prior art.
-
Claim scope aligns with China's patent examination practices, emphasizing inventive step and industrial applicability.
Patent Landscape and Competitive Positioning
1. Prior Art and Novelty:
-
The patent likely differentiates from existing compounds by unique structural modifications, improved stability, bioavailability, or reduced side effects.
