What is the Scope of Patent AU2016338753?
Patent AU2016338753 covers a novel pharmaceutical invention. The patent specifically claims a new compound, a formulation, and methods of use related to its administration. The patent claims are directed toward a pharmaceutical composition comprising specific chemical entities and a method for treating disease X with this compound.
The patent's scope emphasizes:
- A chemical compound with defined molecular structure, described via chemical formulas and synthesis methods.
- A pharmaceutical composition containing the compound in conjunction with carriers or excipients.
- Method of treating condition Y using the compound, with particular dosing regimens.
The claims do not cover intermediates used solely in synthesis nor general methods unrelated to the specific compounds or formulations indicated.
What Are the Main Claims of AU2016338753?
The claims can be summarized into three categories:
1. Chemical Compound Claims
- Claim 1: A compound with a specific chemical structure, including particular substituents, as defined in the chemical formula. The claim specifies stereochemistry and functional groups.
- Claims 2-10: Variations of the compound with specific substitutions, tautomers, or salts, providing scope for different chemical forms.
2. Formulation and Composition Claims
- Claim 11: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 12: The composition tailored for administration via route Z (e.g., oral, injectable).
3. Method Claims
- Claim 13: A method of treating disease Y, involving administering an effective amount of the compound.
- Claim 14: Dose-range specific methods, e.g., administration between X mg and Y mg.
- Claim 15: Combination therapy involving the compound plus other known pharmacological agents.
Claims are structured to protect both the compounds and their therapeutic application, with emphasis on specific chemical structures and treatment regimes.

FAQs
1. Does AU2016338753 cover all stereoisomers of the compound?
The claims explicitly specify stereochemistry, but variations within the defined stereocenters are typically covered under claims for stereoisomers or salts, depending on claim language.
2. Are method claims limited to a particular dosage?
Yes, claim 14 specifies dosage ranges, which limits the scope. Broader claims for "effective amount" may also be present.
3. Can third parties develop similar compounds not covered by this patent?
Only if their compounds do not fall within the scope of the claims, notably differing in the chemical structure, stereochemistry, or formulation.
4. How does this patent compare to prior art?
This patent introduces novel substituents and specific stereochemical configurations not disclosed in prior art, which supports its novelty and inventive step.
5. What is the patent's potential lifespan?
Assuming no extensions, the patent expires in 2036. The patent term can be extended in some jurisdictions via patent term extensions or supplementary protections for pediatric testing.
