Overview of JP5226760
JP5226760 was granted to protect a novel drug-related invention, likely targeting a therapeutic compound, formulation, or method of use for a specific indication. While the detailed specification details are proprietary, publicly available patent database entries reveal the core inventive concept and legal scope through the claims.
Scope of Patent JP5226760
The scope of a patent fundamentally defines the extent of legal protection conferred by the patent rights. For JP5226760, the scope hinges on the phrasing of its claims, which delineate the boundaries of exclusivity.
Independent Claims
The primary claims of JP5226760 are typically independent claims that establish the broad legal protection. These claims are usually structured to encompass:
-
Specific chemical compounds or compositions: The patent likely claims a novel pharmaceutical compound or a class of compounds, which serve as the active ingredient or formulation.
-
Method of use or treatment: Claims may extend to methods for treating particular medical conditions using the claimed compound or composition.
-
Pharmaceutical formulations: Claims may include specific formulations, delivery systems, or methods of manufacturing.
Given the typical structure of drug patents in Japan, the claims probably explicitly specify:
-
The chemical structure or structural formula of the compound.
-
The method of synthesis or preparation.
-
Therapeutic applications, such as indications or treatment regimes.
Dependent Claims
Dependent claims usually specify particular embodiments, such as:
-
Variations in substituents or chemical groups within the core molecule.
-
Specific dosages or administration routes.
-
Combination therapies or formulations with excipients.
These narrower claims serve to provide fallback positions in enforcement and licensing strategies.
Claim Language and Its Implication
The language employed in claims determines their breadth:
-
Broad claims: Utilize functional language and generic chemical descriptors to cover a wide array of compounds or applications.
-
Narrow claims: Focus on specific chemical entities or methods, offering more limited scope but increased robustness against prior art challenges.
In JP5226760, the claims likely strike a balance between broad protection of the core inventive concept and narrower, specific embodiments.
