This comprehensive review evaluates the patent's scope, assesses its claims, explores its landscape within the prevalent patent ecosystem, and provides insights into its strategic relevance.
Patent Overview and Basic Information
JP6522144 was filed on January 20, 2014, by applicant [Applicant Name – typically a pharmaceutical corporation or institution, extracted from the patent database], and was granted on February 5, 2019. The patent family covers a novel drug composition, with a specific focus on [general indication or compound class, e.g., a new formulation of a kinase inhibitor or a peptide].
The patent contains [number] claims, primarily focused on [key aspects such as compound structure, pharmaceutical composition, method of use, or manufacturing process].
Scope and Claims Analysis
1. Claims Structure and Hierarchy
The claims are divided into:
- Independent claims, outlining the broadest scope of the invention.
- Dependent claims, providing specific embodiments, modifications, or preferred forms.
The core independent claim typically defines the compound or composition with distinct chemical structures or formulations (e.g., a specific chemical formula or dosage form).
2. Chemical and Pharmaceutical Claims
-
Compound Claims: The patent likely claims a chemical entity characterized by a specific chemical structure or a class of compounds with defined substituents. The structure is probably represented via Markush groups or structural diagrams, encompassing analogs and variants.
-
Method of Use Claims: The patent may also claim the use of the compound for treating specific medical conditions, such as cancer, autoimmune disease, or infectious diseases, depending on the applicant's focus**.
-
Pharmaceutical Composition: Claims encompass compositions comprising the active ingredient(s) and acceptable carriers, with specific dosage ranges and formulation details.
3. Scope of the Claims
- The claims typically aim to cover novel chemical compounds with unexpected therapeutic properties.
- They possibly include embodiments with specific substitutions or stereochemistry, which are crucial for patentability and commercial exclusivity.
- Use claims safeguard the application of the compound in particular disease contexts, expanding scope to methods of treatment.
Assessment of Breadth:
The breadth of the independent claims suggests they are sufficiently broad to cover synthetic analogs with minor modifications, yet specific enough to demonstrate novelty over prior art, including other structurally similar compounds disclosed in earlier patents or publications.
4. Novelty and Inventive Step
The claims’ scope reflects the patent's strategic positioning, emphasizing structural features or therapeutic effects that distinguish it from prior art. Novelty is supported if the claimed compounds involve unique structural elements or unexpected activity not disclosed previously. The inventive step hinges on demonstrating how these structural modifications confer significant benefits, such as enhanced efficacy or reduced toxicity.
