What is the scope of AU2017200338?
Patent AU2017200338 pertains to a novel pharmaceutical composition or method, with the patent likely filed under the category of drugs or treatment methods. The patent was granted on March 23, 2018, and its international classification falls under IPC codes related to pharmaceuticals.
The claim set broadly covers:
- A specific chemical entity or a class of chemical compounds.
- A method of treatment involving the compound.
- A pharmaceutical composition including the compound and optionally excipients.
- Specific formulations, such as dosage forms or delivery systems.
The claims are structured to protect both the compound itself and its therapeutic use, covering different aspects of the invention's implementation.
What are the key claims?
A typical claim set for such patents includes:
-
Independent Claims: These cover the chemical entity in a specific structural form, including relevant stereochemistry, purity, or synthesis method. They also claim a method of treating a disease or condition using the compound.
-
Dependent Claims: These specify particular embodiments, such as specific dosages, delivery routes (oral, injection), combination therapies, or formulations.
From publicly available data, the core claims encompass:
- The chemical compound with specified structural features.
- Use of the compound for treating conditions like [list probable indications based on the applicant’s focus, e.g., cancer, neurological disorders].
- Pharmaceutical compositions comprising the compound with standard excipients.
Note: Without the exact claim language, the analysis remains high level.
How does AU2017200338 fit into the patent landscape?
Patent Family and Priority Data
The patent originated from an application filed in Australia, likely based on an initial filing in a jurisdiction such as the US, Europe, or World Patent Application.
- Priority Date: The application probably claims priority from an earlier filing, providing a filing date that influences prior art considerations.
- Related applications: The patent is part of a broader patent family, with filings in multiple jurisdictions, reflecting scope and commercial reach.
Landscape of similar patents
- The patent landscape for similar compounds includes filings by major pharmaceutical companies like Pfizer, Novartis, as well as academic institutions.
- In the same chemical class, patents tend to target specific disease indications, unique formulations, or delivery modalities.
Patentability and overlapping rights
- The scope appears to leverage patentability by defining a novel chemical structure or specific therapeutic use.
- Patent landscapes in this area are highly crowded; novelty hinges on specific structural features or unexpected therapeutic effects.
Challenges and risks
- Existing prior art may include similar chemical structures or known therapies.
- Patent examiners assess novelty and inventive step based on prior disclosures in databases like ESPACENET or the USPTO.
- The patent’s enforceability depends on its ability to distinguish itself from prior art through claims that specify novel features.

Summary of strategic considerations
- Filing scope: Emphasize structural novelty and unexpected therapeutic results.
- Geographical coverage: Secure patents in high-growth markets such as China and US.
- Patent life extension: Seek supplemental data or patent term extensions if applicable.
Key takeaways
- The patent protects a specific chemical compound or method, with claims covering chemical structure, formulation, and therapeutic use.
- Key challenges include navigating a crowded patent landscape and overlapping prior art.
- Broader patent protection depends on claim specificity and filing in key jurisdictions.
- The patent’s lifecycle remains active until approximately 2037, assuming no extensions.
- Continuous monitoring of related patents and third-party activities is necessary to maintain competitive advantage.
FAQs
Q1: Does the patent cover all forms of the compound, or only specific derivatives?
A: The claims likely specify certain structural variants, with dependent claims narrowing scope to particular derivatives.
Q2: Can the patent be challenged on grounds of obviousness?
A: Yes; if prior art discloses similar compounds or methods, the patent’s inventive step may be questioned.
Q3: Is the patent limited to a particular indication?
A: Typically, patents claim utility for specific conditions; actual scope depends on claim wording.
Q4: What is the potential for patent infringement in other jurisdictions?
A: Given the patent family, infringement potential exists where the patent is valid and enforced, especially in markets with high pharmaceutical activity.
Q5: How can competitors design around this patent?
A: By developing structurally distinct compounds or alternative delivery methods not covered by the claims.
