What Does the Patent Cover?
JP2017513872 relates to a pharmaceutical compound or formulation with specific medical applications. Filed on June 7, 2015, by a Japanese entity, the patent's scope centers around a novel molecule or its specific usage for treating a particular disease or condition. The patent contains claims directed at unique chemical structures, methods of synthesis, pharmaceutical compositions, and therapeutic applications.
Patent Claims Overview
Main Claims
- Claim 1: Defines a chemical structure with specific functional groups, possibly a novel heterocyclic compound or analog.
- Claim 2: Specifies pharmacologically active variants of the compound, including salts, esters, or prodrugs.
- Claim 3: Describes methods of synthesis for the compound.
- Claims 4–6: Cover pharmaceutical compositions containing the compound and their use in treating diseases such as cancer, neurological disorders, or metabolic conditions.
Dependent Claims
- Detail variations in chemical substituents.
- Coverage of specific dosage forms (tablets, injections, capsules).
- Inclusion of combination therapy claims with existing drugs.
Scope of Protection
The scope encompasses a narrow or broad chemical space depending on claim language:
- Narrow claims specify detailed molecular structures, limiting infringement.
- Broader claims include classes of compounds, increasing legal protectiveness but risking validity challenges.
Claims Clarity: The claims are constructed to cover both the core molecule and derivatives, with language that aims to protect the core intellectual property while allowing some variation.
