Scope and Claims Analysis
1. Claim Structure and Key Elements
The patent's claims form the legal boundary defining the invention’s scope. Typically, patents like JP2012520882 comprise:
- An independent claim(s) outlining the broadest aspect of the invention.
- Multiple dependent claims that narrow or specify features.
In this case, the core independent claim(s) likely cover:
- A chemical compound with a particular structure or functional group.
- A pharmaceutical composition containing the compound.
- A method of use for treating specific diseases or conditions.
Example of plausible independent claim (hypothetical):
"A compound represented by the following formula [structure], or a pharmaceutically acceptable salt, ester, or prodrug thereof, wherein the compound exhibits activity against [target or pathway], and is useful for treating [indication]."
2. Technical Features Covered
The claims may include:
- Specific substituents or configurations in the chemical structure.
- Methods of synthesizing the compound.
- Particular formulation parameters (e.g., dosage, delivery method).
- Therapeutic application scope.
3. Claim Breadth and Limitations
- Broad claims could cover a wide class of compounds, potentially including variations to prevent trivial design-arounds.
- Narrow claims may focus on specific compounds or particular use cases, providing targeted protection but less broad coverage.
Assessment of scope:
Based on typical patent drafting practices, JP2012520882 likely balances broad claims to secure wide protection and narrow claims to mitigate prior art invalidation risks.
4. Potential Patentable Innovations
