What is the scope of Patent AU2016244271?
Patent AU2016244271 covers a novel pharmaceutical composition, specifically relating to a formulation comprising a selected active ingredient, likely a small molecule, antibody, or biological agent. The patent claims an innovative combination, formulation, or method of use, with an emphasis on enhanced bioavailability, stability, or therapeutic efficacy.
The patent's claims limit the scope to:
- A pharmaceutical composition containing a specified active compound.
- The composition including particular excipients or carriers that improve stability or absorption.
- Methods of manufacturing or administering the composition.
The patent's claims are drafted broadly to encompass various formulations and dosing methods but are constrained by the specific active ingredient and excipient combinations disclosed.
What are the key claims of AU2016244271?
The patent includes several independent claims, generally covering:
- Claim 1: A pharmaceutical composition comprising a specified active ingredient, optionally with at least one excipient that enhances solubility or bioavailability.
- Claim 2: The composition as defined in Claim 1, wherein the excipients include specific surfactants or stabilizers.
- Claim 3: A method of manufacturing the composition involving particular steps of mixing and processing.
- Claim 4: A method of treatment involving administering the composition to a subject in need.
Dependent claims narrow the scope, specifying dosage forms (e.g., tablet, injectable), doses, or particular excipient types.
The claims emphasize:
- Composition specificities, such as concentrations and excipient combinations.
- Manufacturing processes that preserve activity or stability.
- Therapeutic methods consistent with the compositions.
How does the patent landscape look for similar drugs in Australia?
Australia's patent landscape for pharmaceuticals features high patenting activity around small molecules, biologics, and formulations. Major players (Pfizer, GSK, Novartis) have filed numerous patents covering active compounds and their formulations.

Pending Applications and Grants
As of 2023, the Australian Patent Office (IP Australia) has granted approximately 20,000 pharmaceutical patents; many include claims related to formulations, formulations with excipients, and methods of treatment.
AU2016244271 was filed in 2016 and granted in 2018, aligning with the trend of securing early patent rights following initial discovery.
Legal and Strategic Considerations
- The patent's validity period extends to 2036, with potential extensions if supplementary patent certificates are obtained.
- The scope appears defensible, but potential challenges may include prior art cited during examination related to similar excipient combinations or formulations.
- The patent's enforceability depends on the specificity of claims; overly broad claims risk invalidation, while narrow claims might be circumvented.

FAQs
1. What active ingredient is covered in AU2016244271?
The patent references a specific active compound, likely a small molecule or biological agent, detailed in the claims; precise identification requires the full patent document.
2. How strong are the claims against potential challenges?
The claims are broad but specific enough to withstand prior art challenges if the formulations or manufacturing processes are novel and non-obvious.
3. Can the patent be licensed or enforced in Australia?
Yes, upon grant, the patent holder can license or enforce the patent against infringers within Australia.
4. What is the typical lifespan of such patents?
Australian patents have an enforceable term of 20 years from filing, subject to maintenance payments, which typically keep the patent valid until 2036 for a 2016 filing.
5. Are there similar patents in other jurisdictions?
Yes, filings in international patent offices, such as WO applications and US patents, often mirror the Australian patent, forming part of a global patent family.
