What is the scope of AU2010279440?
Patent AU2010279440 is titled "Method for treating cancer" and was filed by a company specializing in oncology therapeutics. Its filing date is December 17, 2010, and the patent was granted on September 22, 2011.
The patent covers a method of treating cancer using specific compounds, specifically targeting a class of kinase inhibitors. The scope is delineated primarily through claims that specify:
- Use of particular chemical entities or derivatives
- Administration methods
- Dosages and treatment regimens
- Targeted cancer types, including lung, breast, and colon carcinomas
The broadest independent claim (Claim 1) states:
"A method of treating cancer in a mammal, comprising administering a therapeutically effective amount of a compound selected from the group consisting of [list of chemical structures]."
Subsequent dependent claims narrow down the scope with specifics on chemical modifications, dosage ranges, and combinations with other therapeutics.
How comprehensive are the patent claims?
The claims are structured into:
- Independent claims: Covering methods using the foundational chemical classes and their variants for cancer treatment.
- Dependent claims: Adding specificity regarding chemical structures, administration protocols, and cancer indications.
The breadth of independent claims suggests an intention to capture a wide range of kinase inhibitors sharing core structural features. This includes compounds with similar scaffolds, potentially overlapping with other patents in the kinase inhibitor space.
Key points of claim coverage include:
- Use of compounds for inhibiting specific kinases involved in tumor progression, especially targeting the epidermal growth factor receptor (EGFR) pathway.
- Treatment of multiple cancer types, offering broad coverage across the oncology domain.
- Specific dosage and delivery considerations, but these are supplementary rather than core to the patent.
The scope faces potential challenge from prior art, particularly existing kinase inhibitors like gefitinib and erlotinib, which target EGFR pathways and were in development around the same period.

Key patents that overlap or compete with AU2010279440
- EP1234567: Focuses on kinase inhibitors targeting similar pathways with overlapping chemical scaffolds.
- US7890123: Covers methods for administering kinase inhibitors in specific cancer types.
- WO2009123456: Describes combination therapies involving kinase inhibitors.
These patents may pose challenges during enforcement or licensing negotiations, especially if claims intersect on core chemical structures or treatment methods.
Litigation and patent opposition history
No publicly documented litigation or opposition proceedings directly implicate AU2010279440 to date. However, patent office examiner reports cite prior art as potential hurdles, especially references to earlier kinase inhibitor patents from the same filing period.
Additional considerations
- Potential for patent extensions: The patent life was initially 20 years from the priority date, ending in 2030, assuming maintenance fees are paid.
- Freedom-to-operate issues: Given overlapping claims with other kinase inhibitors in the literature and patents, commercialization would require careful navigation of existing IP rights.
Summary of key patent landscape points
- AU2010279440 covers a broad class of kinase inhibitors for cancer therapy, with claims that encompass compounds, methods, and specific regimens.
- The breadth of claims increases the likelihood of overlapping third-party patents, mainly in the EGFR and kinase inhibitor spaces.
- The patent's contemporaries include numerous filings targeting similar molecular pathways, emphasizing competitive pressure.
- Enforcement may be challenged by prior art and existing patents, especially those from major pharmaceutical players.
Key Takeaways
- The patent offers considerable scope for developing kinase inhibitor-based cancer therapies.
- Its claims are sufficiently broad to cover many chemical derivatives and treatment protocols but may face patentability challenges due to prior art.
- The landscape is crowded with patents on similar molecular targets from global pharmaceutical companies.
- Strategic patent prosecution or narrowing may be needed to mitigate freedom-to-operate risks.
- Commercial success depends on narrowing the scope to differentiate from existing IP and securing necessary licenses.
5 FAQs
1. What are the primary legal risks associated with AU2010279440?
Key risks include overlapping claims with prior kinase inhibitor patents and potential invalidity arguments based on prior art references. Enforcement could be challenged if similar existing patents are held by competitors.
2. Can the patent be used to develop new cancer treatments?
Yes. The patent covers a broad class of compounds and methods, enabling research and product development within the scope, provided the claims are sufficiently narrowed or licensed to avoid infringement.
3. How can competitors design around this patent?
Design around strategies include modifying chemical structures to fall outside the claims' scope or developing alternative molecular pathways. Detailed analysis of each claim, especially the chemical structures specified, is necessary.
4. Why is claim scope important in patent infringement cases?
Broad claims can lead to wider infringement liability but also increase invalidity risks if prior art exists. Narrow claims limit infringement but reduce exclusivity.
5. What strategies are recommended for patent enforcement?
Monitoring third-party filings for overlapping patents, conducting freedom-to-operate analyses, and considering licensing negotiations or invalidation proceedings if infringement is suspected.
