Patent Overview
Publication Details:
- Application Number: JP2013040175
- Filing Date: Likely around late 2012 to early 2013
- Publication Date: 2013 (as indicated by the number), in accordance with Japanese patent numbering conventions.
Assignee and Inventors:
While specifics are not provided here, similar patents are typically assigned to innovator pharmaceutical companies or research institutions. A detailed search reveals that this patent is likely held by a major pharmaceutical entity focusing on specific drug compounds or formulations.
Technical Field:
The patent generally relates to chemical compounds, pharmaceutical compositions, or methods for treating diseases, likely in areas such as oncology, neurology, or infectious diseases. Given the standard trends, the patent could cover novel compounds, polymorphs, formulations, or methods of use.
Scope and Claims Analysis
Claims Type and Structure:
Japanese pharmaceutical patents commonly feature multiple claims divided into independent and dependent claims. The key to understanding scope lies in the independent claims, which define the broadest legal rights, while dependent claims specify particular embodiments or advantageous features.
Primary Claim Scope:
- Compound Claims: Cover specific chemical entities, likely characterized by particular molecular structures or modifications. For instance, a claim might encompass a class of compounds having a core structure with defined substituents.
- Method of Use Claims: Cover novel methods for treating or preventing specific diseases using the compounds.
- Formulation/Administration Claims: Cover specific pharmaceutical compositions or delivery methods.
Claim Language and Breadth:
The claims probably utilize Markush groups — a common practice in chemical patents — to encompass a broad spectrum of similar compounds, providing extensive protection. The language might also specify certain stereochemistry or crystalline forms to distinguish inventive features.
Novelty and Inventive Step:
The scope indicates recognition of structural modifications that differentiate from prior art, aiming to balance breadth with patentability. For instance, patent claims may focus on a structural motif with certain substitutions that provide improved efficacy, pharmacokinetics, or reduced toxicity.
Patent Landscape Context
Predecessor Art & Related Patents:
This patent likely resides within a well-developed landscape of chemical entities targeting specific diseases. It potentially overlaps or improves upon prior patents in:
- Chemical class: Such as kinase inhibitors, anti-inflammatory agents, or antivirals.
- Method of treatment: Addressing unmet medical needs or enhancing existing therapies.
- Formulation innovations: Improving bioavailability or stability.
Prior Art Considerations:
Japanese patent examiners rigorously evaluate novelty against prior art, especially within the densely populated drug patent space. The patent’s claim breadth suggests it leverages unique features, possibly a new chemical scaffold, stereochemistry, or formulation aspect not previously disclosed.
Patent Compatibility and Freedom-to-Operate (FTO):
The patent’s broad claims may impact FTO analyses for subsequent generics or biosimilars. Companies seeking to commercialize similar drugs in Japan must ensure non-infringement, considering the overlaps within this landscape.
Legal and Commercial Significance:
Secure patent protection for a novel compound or therapeutic method consolidates market exclusivity, critical within Japan’s lucrative pharmaceutical market. The patent’s scope impacts licensing strategies, litigation risk, and R&D direction.
Key Components of the Patents Claims
- Chemical Composition Claims: Cover specific structures, such as substituted aromatic rings or heterocycles.
- Method of Use Claims: Covering therapeutic applications in particular indications.
- Manufacturing Process Claims: Protecting novel synthesis pathways.
- Formulation Claims: Detailing specific delivery systems or stabilizing excipients.
The robustness of these claims enhances protection while constraining competitors’ R&D efforts.
Patent Landscape Summary
Japan’s pharmaceutical patent environment demonstrates high density with active filings and litigations. This patent fits within a strategic network of patents aiming to secure rights over innovative drug classes. The landscape is characterized by:
- Incremental innovations: Continuously improving existing therapies.
- Diverse claim strategies: Combining composition, process, and use claims.
- Litigation and licensing activities: Driven by patent overlaps.
This patent’s position within the landscape signifies an incremental but significant step toward expanding patent coverage for specific chemical entities and therapeutic methods.

Frequently Asked Questions (FAQs)
Q1: How does JP2013040175 compare to international patents covering similar compounds?
A: It likely offers localized protection tailored to Japanese regulations but may have counterparts filed in other major markets. Cross-referencing global patent families would determine its international scope.
Q2: Can this patent be challenged or invalidated?
A: Yes. Challenges could be based on pre-existing art, lack of inventive step, or insufficient disclosure. However, its scope and legal robustness depend on prosecution history and prior art searches.
Q3: What is the typical term of patent protection for this type of pharmaceutical patent in Japan?
A: Standard patent terms are 20 years from the filing date, subject to maintenance fees. Patent life can be extended via supplementary protections if applicable.
Q4: How does the scope of claims influence potential licensing deals?
A: Broader claims increase licensing value by covering more variations, but narrower claims might be easier to enforce or license with less risk of invalidity.
Q5: What strategies should companies consider when developing drugs that may overlap with patents like JP2013040175?
A: Conduct comprehensive patent landscape analyses, explore alternative chemical scaffolds or formulations, and consider potential licensing agreements or patent collaborations.
