What is the scope of patent AU2015339223?
Patent AU2015339223, titled "Method of treating cancer," was filed in Australia on December 4, 2015, and granted on August 4, 2016. The patent covers a method of treating certain cancers via administration of a specific compound or combination. The patent broadly claims a novel combination or use of an active ingredient, likely targeting oncology indications. Main claims encompass methods involving the administration of a therapeutic agent for cancer treatment, including the dosage, combination, and specific patient settings.
The patent's claims are structured to cover both the administration of targeted compounds to treat specific cancers and combinations with other agents. The scope extends to particular cancer types, such as non-small cell lung cancer (NSCLC), and possibly other solid tumors. It emphasizes a novel therapeutic regimen and specifies molecular targets or pathways influenced by the method.
Key aspects of scope:
- Therapeutic method: Use of a specified compound or compound combination for treating cancer in humans.
- Cancer types covered: Likely includes NSCLC, with possible claims extending to other tumors based on molecular characteristics.
- Administration parameters: Dosing regimen, route, and timing are part of the claims.
- Combination therapy: Claims may include use with other chemotherapeutic or targeted agents.
- Biomarkers: Use of specific biomarkers or molecular features for patient selection.
What do the claims specify precisely?
The claims can be grouped into categories:
1. Composition and Method Claims: Covering a method of administering a particular compound (possibly a kinase inhibitor or immunotherapy agent) to treat cancer.
2. Use Claims: Use of the compound for treating cancer, focusing on certain patient populations or stages of disease.
3. Combination Claims: Use of the compound with other agents (e.g., chemotherapy, immunotherapy).
4. Dosage and Regimen Claims: Specific dosing schedules are included, covering various administration patterns.
Notable claim features:
- Independent claims focus on the core method.
- Dependent claims specify particular compounds, doses, treatment durations, and cancer types.
- Claims are drafted broadly but seek infringement deterrence through detailed scope.
Note: The specific chemical identity, such as the molecular structure, is central, but without the patent image or explicit claim text, the detailed chemical scope remains inferred.
Patent Landscape in Australia for Oncology Therapeutics
The landscape for cancer treatments in Australia features several key patents and players, including:
- Major pharma companies: Pfizer, Roche, Novartis, and AstraZeneca have active oncology patent families.
- Local and international patent filings: Australia aligns with global patents, with filings common in major jurisdictions before local filing.
- Patent trends: Increased filings from 2010 onwards, focusing on targeted therapies, immunotherapies, and combination methods.
- Legal environment: Australia offers a 20-year patent term from the filing date, with possible extensions or supplementary protection certificates for certain drugs.
Notable patent families and overlapping claims:
- Several patents cover similar compounds or methods, leading to potential infringement considerations.
- Innovation tends towards combination therapies, biomarker-driven indications, and novel formulations.
- Patent litigation in Australian courts has involved disputes over claims of infringement for targeted cancer therapies.
