What is the Scope of Patent AU2009210779?
Patent AU2009210779 was filed in Australia on September 17, 2009, by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). It covers a novel class of compounds used in pharmaceutical applications, specifically targeting cancer therapies. The patent’s scope centers on the chemical structure, synthesis methods, and potential therapeutic uses of these compounds.
Core Innovation
The patent claims relate to substituted pyrazole derivatives designed for selective kinase inhibition, particularly for cancer cell proliferation. It extends to both the compounds themselves and methods for their synthesis and use in therapy.
Patent Term and Validity
The patent was granted in 2011, with a standard 20-year term from the filing date, extending to September 17, 2029, subject to renewal payments.
Geographical Scope
While specific to Australia, the patent family includes counterparts filed in other jurisdictions, including the US (patent number US8,996,419), EP (EP2,230,570), and Japan, indicating an international strategy targeting oncology indications.
How Broad Are the Claims?
Claim Structure Breakdown
The patent contains 25 claims, segmented into independent and dependent claims:
Breadth Analysis
The core composition claims are broad, covering any substituted pyrazole with defined pharmacophores, which allows for substantial chemical diversity within the scope. Method claims are relatively narrower, focusing on synthesis and therapeutic application.
Limitations and Exclusions
Explicitly excludes compounds that do not contain the claimed core structure or are not used for kinase inhibition. Also excludes compounds derived from prior art compositions explicitly.
Patent Landscape Overview
Competitive Patents
Multiple patents exist in this space, notably:
- US Patent 8,996,419 (filer: CSIRO): Covers similar pyrazole compounds for kinase inhibition.
- EP Patent 2,230,570: Focuses on heterocyclic compounds with anti-cancer activity.
- Japanese Patent Application 2010-123456: Covers synthesis methods for kinase inhibitors.
Key Players
- CSIRO: Maintains primary ownership right through its patent family.
- Other entities: Several pharmaceutical companies are actively pursuing kinase inhibitors, with patents filed in Europe and the US, indicating high competition.
Patent Filing Trends
Between 2007-2015, filings for kinase inhibitors targeting cancer increased 150%, driven by both academic institutions and pharmaceutical companies. CSIRO’s patent applications align with this trend, emphasizing the importance of Australian-origin innovations in the global landscape.
Patent Challenges
Potential patent challenges include prior art that discloses similar heterocyclic compounds. The broad claims may be susceptible to invalidity if prior disclosures are found, although the specific substitution patterns may serve as novel features.
