What is the scope of patent JP5432716?
JP5432716 covers a pharmaceutical invention related to a specific compound or method with therapeutic applications, primarily in areas such as oncology, neurology, or metabolic disorders. The patent's scope is defined by its claims, which specify the protected subject matter.
The patent generally emphasizes novel chemical entities, their formulations, and uses in treatment methods. It may include claims on:
- The chemical compound itself, structured with specific chemical groups or modifications.
- Pharmaceutical compositions comprising the compound.
- Methods of preparing the compound.
- Therapeutic methods using the compound or compositions.
The scope aims to prevent third parties from manufacturing, using, or selling similar compounds or methods that fall within the (chemical structure or method) as claimed.
What are the key claims of JP5432716?
The core claims are typically categorized as follows:
Independent Claims
-
Chemical Compound: A novel chemical entity with a specified molecular structure. This claim defines the compound based on chemical formulae, substituents, and stereochemistry.
-
Use or Method of Treatment: A method of treating a disease using the compound, often specifying the dosage, route of administration, or treatment regime.
-
Pharmaceutical Composition: A formulation comprising the compound together with carriers or excipients.
Dependent Claims
- Variations of the compound, such as different salts, polymorphs, or stereoisomers.
- Specific formulations or combinations with other active ingredients.
- Specific dosing regimens or administration routes.
Claim Language
The claims use precise chemical language, often with Markush structures, to define the scope narrowly to avoid prior art. The claims may include ranges for chemical substituents (e.g., "where R1 is selected from...").
