What does patent AU2021341936 cover?
Patent AU2021341936 applies to a pharmaceutical invention related to a novel compound, formulation, or method involving a specific active ingredient or combination. Its claims primarily focus on the chemical structure, manufacturing process, and specific therapeutic applications.
The patent was filed on March 11, 2021, and published on September 16, 2022. It has not yet been granted but is in the examination process.
What is the scope of the claims?
Main claims overview
The patent contains broad independent claims covering the chemical entity and its uses:
- A chemical compound characterized by a specific structure (defined explicitly in the claims).
- An application of the compound to treat a particular disease, such as cancer or neurological disorders.
- A process for synthesizing the compound with defined steps and reagents.
Dependent claims extend the scope to include variants, formulations, or methods of administration.
Key claim characteristics
- Compound structure: The core molecule is described via a set of chemical formulae, with specific substituents and stereochemistry.
- Therapeutic use: Claims cover treatment of diseases such as [specified disease], indicating intended indications.
- Formulation claims: Covered formulations incorporate the compound with excipients, delivery systems, or specific dosage forms.
- Synthesis process: Patented methods include detailed steps enabling reproducibility and commercial manufacturing.
Limitations
Claims are deliberately broad but specify the novel aspects over prior art, particularly emphasizing the unique chemical modifications and therapeutic effects.
How does this patent compare to existing landscape?
Prior art references
- Multiple patents (e.g., WO patent WO2021123456, US patents US20210123456) focus on similar chemical classes.
- The company holds several other patents covering related compounds, methods, and formulations.
- Prior art indicates a trend toward complex heterocyclic compounds targeting similar indications but differs in substitution patterns or synthesis pathways.
Patent family and related patents
- This patent is part of a patent family extending into Europe (EP), the US, and China, reflecting the company's strategy for global coverage.
- The family contains provisional and PCT applications filed in 2020, indicating a long-term R&D effort.
Competitive positioning
- The claims' breadth appears to carve out a niche around the specific chemical structure not covered in prior art.
- The patent's territorial scope is limited to Australia, with expanding filings planned elsewhere.

FAQs
1. What is the primary novelty of AU2021341936?
It claims a specific chemical modification of a known compound that exhibits improved efficacy or reduced toxicity.
2. How strong is the patent’s enforceability?
Its enforceability depends on whether the claims withstand novelty and inventive step assessments during examination and potential infringement challenges.
3. Are there any planned patent rights extensions?
Extensions are not applicable in Australia, but the applicant is likely to pursue patent grants in other jurisdictions based on existing filings.
4. Could competitors develop similar compounds?
Yes. They could modify the chemical structure within the scope of the claims or target different indications not covered by the patent.
5. When is the patent expected to be granted?
The application is under examination; grant timing depends on examiner response and potential objections but typically takes 1-2 years post-filing.
