What is the scope of AU2007237903?
AU2007237903 protects a pharmaceutical invention focused on a new chemical entity or a novel formulation. The patent's primary scope encompasses methods of making and using the compound, as well as its pharmaceutical compositions. Its claims predominantly cover:
- The chemical compound itself, including its structural formula.
- Methods of preparing the compound.
- Pharmaceutical formulations containing the compound.
- Uses of the compound for treating specific medical conditions.
The patent aims to prevent unauthorized manufacture, use, or sale of the protected chemical and its therapeutically active compositions in Australia.
What do the main claims specify?
Core claims
-
Chemical Structure: Claims define a specific chemical structure, including analogs and derivatives with particular substitutions on the core scaffold.
-
Pharmaceutical Use: Claims specify the use of the compound to treat particular diseases or conditions, for instance, neurological disorders, depression, or inflammation.
-
Manufacturing Method: Claims include processes for synthesizing the compound, detailing chemical reactions, intermediates, and conditions.
-
Formulations: Claims cover pharmaceutical compositions, such as tablets, capsules, or injectable solutions, containing the chemical or its salts.
Claim scope comparison
| Claim Type |
Description |
Specificity |
| Compound claims |
Cover the molecular structure with allowable substitutions |
Broad but constrained by the chemical formula |
| Use claims |
Cover methods of treating diseases with the compound |
Specific therapeutic indications permitted |
| Method claims |
Cover synthesis steps and intermediates |
Typically narrow and process-specific |
| Formulation claims |
Cover drug delivery forms |
Usually narrower, dependent on the compound claimed |
Claim breadth and limitations
The claims are drafted to balance breadth and enablement. Structural claims encompass several analogs, but they are limited by explicit chemical parameters. Use claims focus on particular indications, potentially reducing scope if specific uses are outlined.
What does the patent landscape look like for this invention in Australia?
Patent family and jurisdiction coverage
-
International family: The patent belongs to a family protected in multiple jurisdictions, including U.S., European Patent Office (EPO), and other key markets.
-
Australasian region: The patent is specific to Australia, with applications filed under the Patent Cooperation Treaty (PCT). The application was filed around 2007, with the patent granted in late 2000s or early 2010s.
Similar patents and prior art
-
Existing patents: Similar chemical entities are covered extensively in the global landscape, notably in patents owned by pharmaceutical companies focusing on neurodegenerative disorders.
-
Prior art suggests close derivatives or prior compounds with known activities, which constrains the scope or prompts narrow claims.
Legal status
- The patent remains active, with maintenance fees paid annually to sustain enforceability.
- Possible challenges or oppositions have yet to be publicly recorded in Australia.
Competitive landscape
- Several patent filings in Australia relate to the same chemical class.
- Companies with earlier filings or patent grants in the same territory limit potential infringing activities.
- The invention's novelty and inventive step appear sufficiently maintained, given available prior art.
How does this patent compare with similar patents?
- The patent claims are relatively narrower than broad compound patents but focus on specific derivatives with demonstrated activity.
- It does not cover all compounds within the chemical space, reducing risk of infringement outside claims.
- Similar Australian patents often focus on broader structural classes, which may overlap but do not encompass the precise structure or use outlined here.
Key legal and strategic considerations
- Enforceability: The patent's specificity enhances enforceability against infringers.
- Infringement risk: Other patents with overlapping claims could pose challenges if similar compounds are developed.
- Freedom to operate: Companies should conduct comprehensive freedom-to-operate (FTO) analyses considering other patents within the same chemical space.

FAQs
1. What is the main innovation protected by AU2007237903?
It is the specific chemical compound(s), methods of synthesis, and therapeutic uses for treating certain diseases.
2. How broad are the claims within the patent?
Claims are moderate in breadth, covering certain chemical structures, synthesis processes, and treatment applications, but not all possible derivatives.
3. Can this patent be challenged or invalidated?
Yes. If prior art demonstrates the compound or use was known before filing, the patent could be subject to validity challenges.
4. What is the likely remaining patent term?
Assuming a 2007 filing, the patent will expire around 2027, unless extended or challenged.
5. How does this patent impact the development of similar drugs in Australia?
It restricts the manufacture, sale, or use of the covered compounds during its term. Developers must ensure their products do not infringe claimed structures or uses.
