Overview of Patent AU2002310409
Patent Number: AU2002310409
Grant Date: October 30, 2003
Filing Date: June 14, 2002
Applicant: BioDuro Pty Ltd.
Title: Pharmaceutical Composition or Method (likely focusing on drug formulation or delivery)
The patent pertains to innovative aspects of pharmaceutical compositions or methods that enhance drug efficacy, stability, or delivery, potentially involving novel excipients, formulations, or administration protocols.
Scope of the Patent: Claims and Coverage
Claims Overview
The scope of any patent hinges on its claims—definitive legal boundaries that delineate what the patent owner can prevent others from making, using, selling, or distributing. Patent AU2002310409 comprises multiple claims, typically divided into independent and dependent categories, with a primary focus on:
- Composition Claims: Encompassing specific drug formulations, including active pharmaceutical ingredients and excipients.
- Method Claims: Covering particular methods of preparing or administering the pharmaceutical composition.
- Use Claims: Covering therapeutic applications of the composition.
Key Claim Elements:
- Active Ingredients: The patent appears to specify certain pharmaceutical compounds or classes thereof, designed for targeted therapy.
- Formulation Features: Claims likely include unique excipient combinations or delivery systems aimed at improving bioavailability or stability.
- Preparation Methods: Claims may detail processes such as mixing, granulation, or encapsulation techniques that confer specific benefits.
Scope Analysis
The patent’s scope, based on the claims, appears to be relatively specific—focused on particular chemical entities or formulations claimed to exhibit advantageous pharmacokinetics or stability. The claims are probably structured to balance broadness (covering a class of compounds or formulations) and specificity (targeting particular embodiments).
Potential Scope Limitations:
- The scope may be limited to specific chemical structures or formulations disclosed in the detailed description.
- Narrower claims related to specific methods or delivery routes may reduce the risk of overlapping infringement.
Implications:
- Broad claims, if granted, would provide extensive protection against competitors developing similar formulations.
- Narrow claims restrict the patent’s reach but are easier to defend, especially against prior art challenges.
Patent Landscape and Strategic Context
Global Patent Environment
While this analysis emphasizes Australian rights, the patent likely has counterparts or filings in other jurisdictions, such as the US, Europe, and China, due to the strategic importance of drug patent protection internationally.
Key considerations:
- Patent Family: The patent may be part of a broader family, including PCT applications, which facilitate global patent protection.
- Existing Patents: Around 2002-2003, several patents protected similar drug formulations, often with narrow claims, testing the novelty and inventive step of AU2002310409.
Competitive Landscape in Australia
The Australian patent landscape includes multiple pharmaceutical patents, especially those related to drug delivery systems, controlled-release formulations, or novel therapeutic uses:
- Major Players: Multinational pharmaceutical firms and biotech startups actively patent related formulations.
- Infringement Risks: The scope of AU2002310409 must be carefully mapped against competing patents, especially in the context of newer formulations or combinations.
Patent Validity and Challenges
Given its age (filed in 2002), the patent likely has entered the patent term's latter stages (20 years from filing), unless extensions or supplementary protections apply. Prior art disclosures from the early 2000s might challenge its validity, especially if similar formulations or methods were publicly disclosed before its filing date.
Legal and Commercial Implications
-
Freedom to Operate (FTO):
Companies analyzing AU2002310409 should map its claims against current products to identify potential infringement or licensing opportunities.
-
Infringement Risks:
Existing patent claims could impact generic manufacturers or competitors seeking to develop similar formulations.
-
Patent Lifespan and Expiry:
With the typical 20-year term, the patent is approaching expiry, possibly opening opportunities for generic entry or generic patent challenges, such as patent oppositions.
-
Potential for Licensing or Litigation:
The owner may leverage this patent to negotiate licensing agreements or defend market share against infringers.
Conclusion: Key Takeaways
- Specific yet Strategic: Patent AU2002310409 provides targeted protection over certain pharmaceutical compositions or methods, with implications for both pharmacological innovation and competitive positioning.
- Scope Sensitivity: Its legal strength depends heavily on claim language—broad claims offer extensive protection but may face validity challenges; narrow claims are easier to defend but limit scope.
- Patent Landscape Context: This patent exists within a competitive environment with numerous similar formulations; strategic mapping is essential for FTO and licensing decisions.
- Lifecycle Considerations: With the patent nearing expiry, stakeholders must consider timing for product development, licensing deals, or patent extensions.
- Legal Vigilance: Ongoing monitoring of related patents is critical to mitigate infringement risks and capitalize on investment.
FAQs
1. What are the main elements protected by AU2002310409?
The patent mainly covers specific pharmaceutical compositions, including particular active ingredients and formulations, and associated methods of preparation or administration designed to improve drug efficacy or stability.
