Patent Overview and Bibliographic Data
- Patent Number: JP2017052794
- Application Filing Date: Corresponds approximately to the year 2017
- Publication Date: Typically within a year or two following filing — in 2017 or 2018
- Applicant: Likely a Japanese pharmaceutical or biotech corporation (e.g., Takeda, Astellas, or similar), though precise applicant details should be verified from the official source.
- Priority: Often based on earlier filings in Japan or foreign applications.
- Technical Field: Likely related to pharmaceuticals, chemical compounds, or formulations, given the context and common practices.
Scope of the Patent
Scope refers to the extent of protection conferred by the patent claims, defining what is legally protected and the boundaries of the patent rights.
Broad Approach
The scope of JP2017052794 is delineated through its claims, primarily focusing on a novel chemical entity, composition, or method of use relevant to treatment, diagnosis, or drug delivery. The scope is designed to encompass:
- Novel compounds or derivatives with specific chemical features.
- Pharmaceutical compositions containing these compounds.
- Methods of manufacturing or administering the compounds.
- Therapeutic methods for specific indications.
Scope Considerations
Given the typical strategy in pharmaceutical patents, it is probable that the claims encompass both:
- Compound Claims: Covering specific chemical structures with defined substituents.
- Use Claims: Covering methods of treatment or prophylaxis using the claimed compounds.
- Formulation Claims: Covering specific formulations, dosage forms, or delivery mechanisms.
The scope's breadth is likely modulated to balance protection with the need to withstand potential validity challenges, especially given Japan's stringent patent examination standards.
Detailed Claims Analysis
Claims Structure Overview
Patent claims in pharmaceuticals generally divide into independent and dependent claims:
- Independent Claims: Set the core scope, typically covering the novelty compound or method.
- Dependent Claims: Narrow the scope further, adding specific features, such as particular substituents, stereochemistry, or formulations.
Claims of JP2017052794
1. Compound Claims
- Likely define a chemical structure characterized by specific core moieties, possibly with substituents or stereochemistry that confer therapeutic activity.
- Emphasis on chemical parameters such as molecular formula, particular bonds, or stereoisomers.
- Example: "A compound of formula (I), wherein R1 and R2 are..."
2. Use Claims
- Claim methods involving the administration of compounds for treating diseases—probably targeting cancers, neurological disorders, or infectious diseases.
- Example: "Use of the compound of claim 1 in the preparation of a medicament for treating [indication]."
3. Formulation and Composition Claims
- Cover pharmaceutical compositions containing the compound and excipients.
- May specify dosage forms such as tablets, injections, or sustained-release formulations.
4. Method Claims
- Encompass novel synthesis or production processes for the compounds.
- Claims may also include specific administration protocols or combination therapies.
Claim Scope Focus Points
- Specificity vs. Breadth: The patent probably balances detailed chemical definitions to maintain validity while broad enough to prevent workaround.
- Stereochemistry and Isomers: Might include claims on stereoisomers or polymorphs, which are critical in pharmaceutical patents.
- Indications: The patent likely specifies therapeutic indications, which define its utility scope; broader claims may cover multiple diseases or conditions.
Patent Landscape in Japan
Key Players and Competitors

FAQs
1. How does JP2017052794 compare to foreign patents in the same class?
It likely shares core chemical features with international counterparts but differs in specific structural claims or treatment methods, providing Japan-specific protection.
2. Can the scope of the patent be challenged in Japan?
Yes, via post-grant opposition or invalidity proceedings, especially if prior art or obviousness grounds are established.
3. How broad are typical chemical compound claims in Japanese pharmaceutical patents?
They range from specific isolated compounds to broader genus claims; however, Japanese examiners favor well-defined, supported claims with clear inventive steps.
4. What strategies can third parties undertake to avoid infringement?
Conduct detailed claims mapping, focus on non-overlapping chemical classes, or develop compounds outside the scope of the claims.
5. What should patent owners consider for maintaining patent validity in Japan?
Regular supplementation with data supporting inventive step, adherence to formal requirements, and monitoring of similar patents are critical.
