- Applicants: Often, such patents are filed by pharmaceutical companies, research institutions, or biotech entities.
- Jurisdiction: Japan, with potential extensions or equivalents in other jurisdictions.
Abstract Summary
While the full patent document is required for precise details, patent JP2013523611 generally concerns a novel pharmaceutical compound, a specific chemical entity or class, along with compositions and methods for treating particular conditions, such as cancers, neurological disorders, or metabolic diseases.
2. Scope of the Patent
Scope Definition
In Japanese patent law, the scope is primarily determined by the claims, which define the legal boundaries of patent protection. The patent’s scope encompasses:
- Chemical compounds: Specific molecular structures, classes, or derivatives.
- Use claims: Therapeutic applications in particular diseases.
- Formulation claims: Methods of preparing the drug or dosage forms.
- Method claims: Treatment methods or diagnostic procedures.
Typical Claims Analysis for JP2013523611
- Compound claims: Cover a novel chemical entity, characterized by a specific core scaffold with defined substituents. For example, a heterocyclic compound with particular functional groups.
- Purposes: Claiming the compound’s use in treating diseases, e.g., “a method of treating cancer by administering compound X.”
- Formulation claims: Pharmaceutical compositions comprising the compound with carriers or excipients.
- Method claims: Including methods of synthesis or administration techniques.
The patent likely emphasizes the novelty and non-obviousness of the chemical structure or its therapeutic effect, which broadens or narrows the claimed scope.
3. Claims Structure and Breadth
The claims are pivotal, delineating the scope of legal protection and determining potential infringement or validity challenges. Typical structures include:
- Independent Claims: Broadly covering the specific compound or its therapeutic application.
- Dependent Claims: Narrower claims adding features like specific substituents, formulations, or methods of synthesis.
Possible claim types in JP2013523611
- Compound claim: “A compound of formula I, wherein the variables are as defined…”
- Use claim: “Use of compound I in the treatment of disease Y.”
- Method claim: “A method for synthesizing compound I…”
- Composition claim: “A pharmaceutical composition comprising compound I and a pharmaceutically acceptable carrier.”
The breadth of the claims directly impacts patent valuation and defensive strength. Broad claims covering general chemical classes or therapeutic methods provide wider protection but often face higher validity scrutiny.
4. Patent Landscape
Global Patent Landscape
In the domain of novel pharmaceuticals, the patent landscape involves:
- Primary patent families: Similar compounds or therapeutic methods patented globally, especially in large markets such as US, Europe, and China.
- Secondary portfolios: Patents on formulations, methods, and manufacturing processes that support the core innovation.
- Patent thickets: Overlapping patents that could block market entry or limit freedom to operate.
Similar Japanese and International Patents
- Prior Art References: The patent examiners would have examined prior compounds and therapies, distinguishing JP2013523611 through unique structural features or unexpected therapeutic effects.
- Related Patents: Patent families from competitors or collaborators focusing on overlapping chemical scaffolds or indications.
Patent Cited Documents and Interactions
- Likely, prior art references include earlier patents on similar compounds, such as WO or US patents, that disclose related chemical structures or therapeutic uses.
- The patent’s defensive strategy may involve overlapping claims with existing patents, emphasizing novel structural features or unexpected pharmacological properties.
5. Strategic Implications
For Innovators
- The scope suggests the patent protects key chemical entities and their pharmaceutical applications, serving as a core asset in a patent portfolio.
- The scope’s breadth determines the freedom to operate: overly broad claims may face validity challenges; narrower claims may limit exclusivity.
For Competitors
