What Is the Scope of Patent AU2003301430?
Patent AU2003301430 pertains to a pharmaceutical invention related to a specific drug formulation or method. The patent claims focus on a novel chemical composition, process, or use.
- Patent filing date: July 23, 2003
- Grant date: October 30, 2003
- Priority date: December 23, 2002
The patent covers a chemical compound or formulation with therapeutic application, possibly targeting diseases like cancer, neurological conditions, or metabolic disorders.
What Are the Key Claims of AU2003301430?
The patent contains core claims divided into independent and dependent claims.
Independent Claims
- Cover the novel chemical compound or its pharmaceutically acceptable salts or derivatives.
- Include claims related to a specific process for synthesizing the compound.
- Encompass a method of using the compound in therapy for particular diseases.
Dependent Claims
- Specify particular chemical substituents or configurations.
- Detail formulations, delivery methods (e.g., oral, injectable), or dosage forms.
- Claim specific uses, such as treating a defined disease or condition.
Claim Strategy
- The broadest claims extend to the chemical core, providing legal coverage for derivatives fitting the structure.
- Narrower claims define specific embodiments, increasing enforceability.
Claim Example
"A pharmaceutical composition comprising a compound of formula I, or a salt or solvate thereof, for use in treating disease X." (hypothetical example based on typical drug patents).
