What is the Scope of Patent AU2015340373?
Patent AU2015340373 pertains to a pharmaceutical invention. Its primary focus is a novel formulation or method related to a specific drug substance or combination. The scope includes:
- The chemical composition of the formulation.
- Specific methods of manufacturing.
- Use claims centered on treating particular conditions related to the active ingredient(s).
- Variations or modifications that fall within the inventive concept.
The patent's claims aim to protect both the composition and its method of use, potentially covering formulations with unique excipients or delivery mechanisms.
What Are the Key Claims of AU2015340373?
The patent document contains multiple claims, commonly divided into independent and dependent claims.
Independent Claims
-
Composition Claim: Describes a pharmaceutical formulation with a specified active ingredient, possibly including a particular dosage form (e.g., tablet, capsule, suspension).
-
Method of Use Claim: Covers a method of treating a specific medical condition using the composition.
-
Manufacturing Process Claim: Details a process for preparing the formulation with claimed advantages (e.g., stability, bioavailability).
Dependent Claims
-
Variations of the composition with different excipients, preservatives, or stabilizers.
-
Specific dosage ranges for the active ingredient.
-
Alternative methods of administration such as oral, injectable, or topical.
Notable Limitations
-
Claims specify the chemical structure or generic class of the active agent to prevent easy design-around.
-
The claims may include scope for derivatives or analogs that share the core structural features.
