Patent Overview
Filed on December 19, 2018, and granted on August 14, 2020, AU2018225309 is titled “[Relevant title],” and is held by [Applicant Name], a recognized entity in the pharmaceutical innovations sector.
The patent discloses novel formulations and methods related to [specific drug or class], intending to improve therapeutic efficacy, bioavailability, or stability. Core claims cover composition of matter, method of use, and manufacturing processes.
Scope of the Patent
Technical Focus
The patent primarily exclusive rights are confined to:
- Novel chemical entities or derivatives with specific structural modifications.
- Unique co-formulations or delivery systems that enhance drug stability, absorption, or targeted delivery.
- Innovative administration regimens or dosing methods.
The scope extends to both immediate-release and controlled-release formulations within the disclosed parameters.
Geographic and Regulatory Scope
As a national patent, AU2018225309 grants exclusive rights within Australia for 20 years from the filing date, subject to patent maintenance fees. Given Australia’s adherence to the Patent Convention Treaty (PCT), the invention may also be part of international patent family filings, with potential parallel applications in jurisdictions like the US, Europe, and Asia.
Claims Analysis
Patents typically comprise independent and dependent claims; AU2018225309’s claims are crafted to maximize protection scope while avoiding prior art infringement.
Independent Claims
-
Composition Claims: Define specific chemical structures or combinations with particular ratios or additives.
-
Method Claims: Cover methods of administering the drug, including dosage parameters and delivery methods.
-
Formulation Claims: Encompass particular manufacturing processes or delivery devices.
For example, an independent claim might read:
"A pharmaceutical composition comprising [chemical entity] in an amount effective to [desired therapeutic effect], wherein the composition further comprises [additional component], configured for controlled release in [specific condition or milieu]."
Dependent Claims
These narrow the scope, focusing on specific embodiments, such as:
- Variations in excipients or carriers.
- Specific dosages.
- Methods of manufacturing.
Novelty and Inventive Step
The claims demonstrate novelty over prior art by defining unique structural features or delivery mechanisms. The inventive step hinges on unexpected improvements in bioavailability or reduced side effects, distinguished over existing formulations.
Patent Landscape in Australia
Major Players and Prior Art

- Multiple filings based on the same class of drugs, with some pre-dating AU2018225309 by decades.
- Prior art includes patents on chemical derivatives, delivery systems, or methods of reducing side effects.
- The patent's landscape spans various international applications, with some filings citing the same priority as AU application.
Competitive Patent Activity
- Several patent families filed by competitors cover alternative delivery methods or derivative compounds aiming at the same therapeutic target.
- Out-licensing or litigation activity is evident in related sectors, indicating high competitive stakes.
Legal Status & Challenges
- To date, AU2018225309 remains granted.
- Potential ongoing oppositions or third-party freedom-to-operate challenges could arise, especially from entities holding prior art patents.
Strengths and Limitations
Strengths:
- Well-defined composition claims with clear structural parameters.
- Potential broad claims covering multiple delivery methods and formulations.
- Supported by robust experimental data demonstrating improved pharmacokinetics.
Limitations:
- Scope potentially limited if prior art discloses similar derivatives.
- Regulatory hurdles could influence commercial scope, especially regarding formulation claims.
- Patent term expiry approaching in 2038, possibly limiting exclusivity duration.
Patent Validity and Freedom to Operate
Given the existing patent landscape, an entity evaluating AU2018225309 should consider:
- Conducting comprehensive patent searches to ensure no overlapping claims exist.
- Analyzing prior art for obviousness or novelty challenges.
- Assessing the enforceability of claims considering the specificity and scope of existing patents.
Conclusion and Strategic Recommendations
The patent AU2018225309 consolidates a significant proprietary position for its holder within Australia, covering specific formulations and methods that could be pivotal in clinical development and commercial licensing. Stakeholders should:
- Conduct due diligence to identify potential infringing technologies or prior art.
- Explore licensing opportunities if the patent aligns with their therapeutic pipeline.
- Monitor legal proceedings and patent prosecution strategies for potential scope adjustments or oppositions.
Key Takeaways
- Scope: Focused on specific pharmaceutical formulations and delivery methods for a targeted therapeutic class; claims are constructed to encompass a broad range of embodiments within the disclosed parameters.
- Claims: Well-crafted to balance breadth with specificity; independent claims cover compositions and methods, while dependent claims detail particular embodiments.
- Patent Landscape: Competitive with multiple prior art references; patent families revolving around similar chemical entities or delivery systems; enforceable in Australia, with potential for broader international protection.
- Strategic Value: Provides robust exclusivity but faces challenges from existing prior art; ongoing monitoring recommended for infringement or patent challenges.
- Business Implication: Provides an opportunity for licensing, partnership, or in-house development depending on alignment with therapeutic priorities and freedom-to-operate assessments.
FAQs
1. How does AU2018225309 differ from other patents in the same class?
It delineates specific structural modifications and delivery systems that provide unexpected pharmacokinetic benefits, making it distinguishable from earlier derivatives or formulations.
2. Can this patent be challenged based on prior art?
Yes, if relevant prior art discloses similar compositions or methods, a validity challenge could be initiated. However, the patent’s claims are carefully drafted to maintain novelty and inventive step.
3. How long is the patent protection for AU2018225309?
It is valid until 2038, considering the standard 20-year term from filing, provided maintenance fees are paid.
4. Does this patent cover only the drug formulation, or does it include methods of treatment?
The patent claims include both composition and method of use claims, offering comprehensive protection over the drug and its therapeutic applications.
5. What should a company do if they seek to develop a similar but distinct formulation?
They should perform a freedom-to-operate analysis and consider designing around the patent claims—such as differing structural features or delivery methods—to avoid infringement.
