Patent Overview and Basic Details
JP2013528162, filed in Japan, was published on December 19, 2013, with priority claims possibly from earlier applications. The patent claims a novel therapeutic compound, formulation, or method of use, designed to address specific clinical indications. While the exact chemical structures or therapeutic targets are proprietary, the patent’s language signals a focus on [insert specific therapeutic area, e.g., oncology, neurology, infectious diseases].
The applicant, assignee, or inventor details are crucial; however, without explicit access here, the analysis proceeds based on the typical scope and potential claims aligned with similar patents.
Scope and Claims Analysis
Independent Claims Overview
The core strength and breadth of JP2013528162 rest within its independent claims. These claims likely define:
- Chemical or biological composition: A novel compound or a family of compounds with a defined chemical structure or class.
- Method of synthesis: Specific processes to produce the compound.
- Therapeutic use: A method of treating or preventing a particular disease or condition.
- Formulation aspects: Dosage forms, delivery systems, or combinations.
Key features of the claims:
-
Chemical Structure and Definition: The patent probably claims a compound with a specific molecular structure, including substituents and stereochemistry, to distinguish it from prior art. Such claims are usually broad, covering all derivatives within the defined scope.
-
Use Claims: These specify the treatment or diagnostic method, focusing on novel therapeutic effects or targeting specific receptors or pathways.
-
Manufacturing Claims: Innovations in the synthesis process or formulation, which improve yield, stability, or delivery.
Claim Limitations and Scope
The scope is possibly constrained by:
- Novelty requirements: The claimed compound must differ sufficiently from prior art, including previous patents and scientific literature.
- Inventive step: Demonstrating an inventive step over existing compounds or methods.
- Specificity of therapeutic application: Claims might specify diseases or conditions, although broader 'use of' claims are common.
Implication: The scope remains robust if the claims are carefully drafted to cover derivatives and methods, yet vulnerable to design-around strategies if overly narrow.
Patent Landscape and Comparative Analysis
Position within the Japanese Patent System
Japan's patent environment emphasizes detailed disclosure, with strict examination standards for novelty and inventive step, especially in pharmaceuticals. JP2013528162 not only secures the compound’s protection but also potentially blocks competitors from manufacturing, using, or importing similar compounds within Japan.
Global Patent Landscape
- Prior Art and Existing Patents: Similar patents filed in Europe (e.g., EP patents), the US (e.g., US patents), and other jurisdictions often cover related chemical classes or therapeutic uses. Patent families might extend or overlap, requiring strategic analysis of potential infringement or freedom-to-operate (FTO).
- Patent Families and Related Applications: It's likely this patent is part of a broader family, with applications in China, Europe, and the US, reflecting a global patenting strategy.
Key Competitor IP and Patent Thickets
The patent landscape surrounding JP2013528162 probably contains numerous prior art references, including:
- Existing patents on similar compounds.
- Method of use patents targeting similar indications.
- Synthesis route patents.
Understanding the overlapping claims helps gauge the strength of JP2013528162’s protective scope and potential challenges in enforcement.
Innovation and Patent Strengths
- Chemical novelty: The uniqueness of the compound's structure or formulation.
- Therapeutic claims: Specific indications or mechanisms of action that fill unmet medical needs.

FAQs
Q1: How does JP2013528162 compare to similar patents in the US or Europe?
A: While similar in claiming a novel compound or method, jurisdiction-specific nuances in claim language, patent examination procedures, and prior art databases influence scope and enforceability. Cross-referencing with US and European patents helps identify overlaps and differences.
Q2: Can the claims of JP2013528162 be easily circumvented by competitors?
A: Potentially, if competitors design around chemical structures or methods outside the claimed scope. Narrower claims are more vulnerable, whereas broader claims are better protected but harder to obtain and defend.
Q3: What is the typical patent lifespan for pharmaceuticals in Japan?
A: Generally, 20 years from filing date, with possible extensions (up to 5 years) under supplementary protection certificates, especially relevant when patent term losses occur due to regulatory delays.
Q4: How critical is it to monitor prior art when prosecuting such patents?
A: Extremely critical; thorough prior art searches ensure the patent's claims are sufficiently novel and inventive, reducing risk of invalidation or opposition.
Q5: What strategies can extend the commercial lifecycle beyond patent expiry?
A: Developing secondary patents on formulations, manufacturing processes, or new therapeutic uses can prolong exclusivity, while patent term extensions may supplement patent life.
