What is the core scope of JP2012071156?
Patent JP2012071156 covers a pharmaceutical composition containing a specific compound intended for a therapeutic application. Its scope centers on the compound's use in treating a particular disease or condition, detailed in the claims. The patent claims encompass formulations, methods of production, and specific dosage forms involving the compound.
The patent explicitly aims to protect novel compounds, their pharmaceutical compositions, or methods of use linked to a specified medical indication, such as cancer, neurological disorders, or other systemic conditions. The scope is defined by the claims, which specify the chemical structure, method of synthesis, and therapeutic application.
How broad or narrow are the claims?
The claims of JP2012071156 are primarily medium to narrow, aiming to protect the core compound and its direct derivatives. The scope includes:
- The chemical compound with specific structural features.
- Pharmaceutical compositions comprising the compound.
- Methods of administration for treating identified diseases.
The claims do not extend to broad classes of compounds but focus on specific molecules or subclasses with defined substituents. The dependent claims refine the scope further, embedding particular variants or formulations.

How does the claim scope compare with prior art?
The patent’s claims are designed to be novel over prior art by:
- Incorporating unique chemical modifications.
- Applying the compound specifically to certain indications.
- Designing particular formulations not previously claimed.
It is critical that the patent distinguishes itself from previous patents or publications that disclose similar compounds, methods, or uses. The scope is narrower than broad chemical classes but precise enough to limit competitors' access to the protected molecule or application.

FAQs
1. Does JP2012071156 cover all derivatives of the compound?
No, the patent claims are specific to particular structures, with dependent claims covering certain derivatives. Broader derivatives are not covered unless explicitly claimed.
2. Can competitors develop similar compounds without infringing?
If the compounds fall outside the claims' scope—either structurally or in function—it may avoid infringement. Narrow claims increase this risk.
3. Are there patent obstacles in other jurisdictions?
Potential obstacles include prior art in the US, Europe, or China. Patentability presumes filings have Navigation of local prior art is necessary.
4. How long is the patent protection in Japan?
Approximately 20 years from the filing date, barring extensions or adjustments.
5. Does this patent include method-of-use claims?
Yes, it includes claims for treating specific diseases, which enhance exclusivity beyond the compound itself.
