Scope of Patent JP2010509331
Application of the Patent
The patent claims focus on:
- Therapeutic use of a certain compound in cancer treatment.
- Method of administration for cancer intervention.
- The composition comprising the active compound and pharmaceutical carriers.
- Biomolecular interactions or pathways targeted by the compound.
Key Features of Scope
-
Disease Indications: While primarily targeting various cancers, the scope may encompass specific types such as lung, breast, or colorectal cancers, depending on explicit claim language.
-
Active Compound Class: The patent primarily covers a specific chemical entity or a class of compounds with similar structures, emphasizing their role in inhibiting a particular receptor, enzyme, or signaling pathway.
-
Treatment Methodology: The claims include methods for administering the compound, dosage regimens, or combination therapies to optimize cancer treatment.
Limitations and Boundaries
The scope is explicitly bounded by the:
-
Chemical structure or class of the compound, preventing others from using similar compounds for cancer therapy without infringing.
-
Therapeutic context, limiting claims to methods of preventing or treating cancer using the specified compound.
-
Specific biomolecular targets as defined in the claims, such as a particular receptor or kinase involved in tumor proliferation.
Claims Analysis
JP2010509331 comprises several claims, typically segmented into independent and dependent claims.
Independent Claims
-
Claim 1: Likely defines a method for treating cancer using a compound with a specified chemical structure or its pharmaceutically acceptable salt, crystal form, or composition.
-
Claim 2: Defines a pharmaceutical composition comprising the compound plus excipients.
-
Claim 3: Covers the method of administering the compound in specific dosages or routes (e.g., oral, intravenous).
-
The core independent claims establish the patent's exclusivity over the compound's uses in specific therapeutic contexts.
Dependent Claims
- Cover specific molecular modifications, salts, formulations, or dosing regimens.
- May specify particular cancer types, treatment combinations, or treatment durations.
- Enhance the scope and detail, but do not significantly broaden the fundamental patent rights.
Claim Clarity and Breadth
The claims appear carefully drafted, balancing broad protection over a class of compounds and specific treatment methods. They encompass:
- Chemical scope: Likely broad enough to cover derivatives with similar structures.
- Therapeutic scope: Focused on treatment of cancers but adaptable to different stages or combination therapies.
However, patent scope could be challenged if prior art reveals similar compounds or methods, which is common in this field.
