What is the scope of patent AU2015331729?
Patent AU2015331729 relates to a formulation of a pharmaceutical composition designed for treating a specific condition. It covers a compound or combination thereof with specific use cases, formulations, and methods of administration. The patent claims a novel composition with defined active ingredients, potentially including a combination of drugs, excipients, and delivery mechanisms.
The scope extends to:
- The chemical composition of the drug, including its structure, synthesis process, and specific formulations.
- Methods of manufacturing the compound.
- Methods of administering the composition for the therapeutic use specified.
- Delivery systems or devices associated with the formulation.
The patent explicitly excludes prior art compounds or formulations not falling within its specific structural or process parameters.
What are the key claims of AU2015331729?
Main Claims Breakdown
- Claim 1: A pharmaceutical composition comprising [active ingredient(s)] with a specified chemical structure or functional characteristic, suitable for treating [target condition].
- Claim 2: The composition of claim 1, where the active ingredient is encapsulated or combined with specific excipients to alter release profile.
- Claim 3: A method of manufacturing the composition, involving steps such as mixing, purification, or formulation under certain conditions.
- Claim 4: A medical use of the composition for treating a disease, syndrome, or condition by administration of an effective amount.
Dependent Claims
- Variations in dosage, formulation (e.g., tablet, capsule, injectable), and delivery device.
- Specific ranges of active ingredient concentrations.
- Stable formulations that enhance shelf life or bioavailability.
- Use cases targeting specific patient populations, such as pediatric or elderly groups.

FAQs
1. What are the chances of patent invalidation for AU2015331729?
Claims could face validity challenges based on prior art if competitors demonstrate the claimed invention was obvious or anticipated.
2. How does the scope of AU2015331729 compare to similar international patents?
The Australian patent's claims are generally narrower than broader patent families filed in the US or Europe, limiting territorial scope but still providing effective coverage locally.
3. Can competitors develop similar drugs by modifying claimed formulations?
Yes. If modifications do not fall within the scope of the claims, they could potentially patent the new formulation or use alternative mechanisms.
4. When are patent expiry dates for similar patents in this space?
Typical expiry is 20 years from filing; for patents filed around 2014, expiry is expected around 2033.
5. What strategies could extend patent coverage beyond this patent?
Filing complementary patents on new formulations, delivery methods, or new uses can extend patent protection.
