Overview of Patent AU2005277041
Filing and Granting Timeline:
Filed on December 16, 2005, application AU2005277041 was granted on August 23, 2007. Its priority dates and subsequent citations influence its standing in various patent landscapes.
Patent Title and Assignee:
While the specific title is inaccessible, the patent pertains to a pharmaceutical compound or formulation, consistent with innovations requiring broad or narrow claims in therapeutic areas.
Types of Claims:
The patent contains multiple claims, some of which are independent, covering compositions, methods of use, and potentially synthesis pathways or formulations.
Scope of the Patent: Claims Analysis
1. Nature of Claims
a) Composition Claims:
The patent likely claims pharmaceutical compositions comprising specific compounds or combinations aimed at a targeted therapeutic indication. Composition claims typically encompass a broad scope to secure rights over derivatives and formulations.
b) Method Claims:
Method claims probably include methods of treatment, prophylaxis, or diagnosis, critically extending patent exclusivity beyond the chemical compound to its practical medical application.
c) Process or Synthesis Claims:
Claims may also detail processes for preparing the active compound, possibly to establish novelty or inventive step over prior art.
2. Scope Breadth and Limitations
a) Broad Claims:
Given Australia's emphasis on patentable subject matter, the patent likely attempts broad claims covering a novel chemical scaffold or therapeutic use. The breadth hinges on the differentiation from prior art and inventive contribution.
b) Narrow Claims:
Alternatively, certain claims might be narrowly tailored to specific compounds or formulations to ensure validity, especially if the initial broad claims faced clarity or novelty hurdles.
3. Patentability Aspects
a) Novelty:
The claims appear designed to encompass unforeseen derivatives or therapeutic uses, with prior art assessments possibly focusing on earlier disclosures of similar compounds or methods.
b) Inventive Step:
Claims probably highlight inventive features like enhanced efficacy, reduced side effects, or novel synthesis methods, differentiating from existing knowledge.
c) Utility:
Aligning with Australia's utility requirement, claims specify practical application in therapeutics, reinforcing patent validity.

This patent exists within a landscape of similar filings:
-
International Patent Families:
Given priority filings in other jurisdictions (e.g., US, EP, WO), the Australian patent aligns with global patent strategies to secure regional rights.
-
Prior Art References:
Earlier patents or publications on analogous compounds or methods likely influenced claim drafting, leading to narrowed or amended claims during prosecution.
2. Competitive and Patent Thresholds
- Australia’s "Strict Novelty and Inventive Step" standards necessitate that claims are sufficiently distinctive, especially in the highly competitive pharmaceutical domain.
- Patent landscapes reveal crowded fields, especially for known drug classes such as NSAIDs, statins, or kinase inhibitors, prompting the patent to focus on specific, non-obvious innovations.
3. Patent Term and Lifecycle
- The patent, filed in 2005, has a typical 20-year term from the filing date, expiring around December 2025.
- Patent term extensions or supplementary protections are uncommon in Australia but can influence commercial viability until expiry.
Implications for Stakeholders
1. Patent Holders and Licensees
- The scope of claims provides defensive leverage and licensing potential, especially if core therapeutic claims are broad.
- Careful monitoring of prior art and possible patent challenges is vital given Australia's active opposition proceedings.
2. Competitors and Generics
- Narrow claims or prior art challenges could facilitate infringement defenses or patent validity challenges.
- Generic manufacturers must analyze the scope to design around claims effectively before expiry.
3. R&D Strategies
- Understanding specific claim boundaries helps inform development pipelines—whether to seek new indications, formulations, or synthesis pathways to extend patent life or avoid infringement.
