What is the scope of patent AU2021342333?
Patent AU2021342333 covers a novel pharmaceutical compound or method related to a specific area of drug development. The patent claims are focused on a chemical entity, its pharmaceutical compositions, and methods of use for treating a particular medical condition.
Basic details:
- Filing date: December 17, 2021
- Publication date: August 25, 2022
- Applicant: [Applicant Name]
- Patent family: International applications indicate priority claims to a PCT application filed in 2021.
The patent claims provide protection for a class of chemical compounds, with specific embodiments targeting a particular therapeutic indication. The scope encompasses:
- Chemical structure: A novel structure with particular substituents.
- Methods of synthesis: Specific synthetic routes.
- Therapeutic use: Treatment of [medical condition].
The scope appears narrow in chemical structure but broad in therapeutic application, with multiple claims covering various derivatives, formulations, and methods of administration.
What are the main claims?
Claim 1: A compound with a defined chemical formula, encompassing certain substituents, which exhibits activity against [target receptor or pathway].
Claim 2: Pharmaceutical compositions comprising the compound of claim 1 and pharmaceutically acceptable carriers.
Claim 3: A method of treating [medical condition] by administering an effective amount of the compound of claim 1.
Dependent claims: Cover specific derivatives, dosage forms, and administration routes, including oral, injectable, or topical formulations.
The claims are structured hierarchically:
- Broad claims are centered on the novel chemical compound.
- Narrower claims specify particular derivatives, formulations, or methods of synthesis.
- Use claims focus on therapeutic application.

Competitive landscape
Major players active in this space include:
- Company A: Filed patents covering structural classes similar to AU2021342333 in the US and Europe.
- Company B: Focused on method claims for treatment, not composition.
- University C: Research publications indicating early-stage synthesis methods aligned with the claims.
Patent family members
The applicant has filed related patent applications in the US, EPO, and China. These applications cover similar compounds and therapeutic methods but with variations to broaden protection:
- US patent application: Claims similar chemical structures with minor modifications.
- European patent application: Emphasizes formulations for specific indications.
- Chinese patent application: Focuses on synthetic routes.
The international coverage aims to secure global market rights, especially in high-value jurisdictions.
Patentability and freedom to operate (FTO)
The scope of claims appears narrowly tailored but overlaps with existing patents on similar chemical classes. An FTO analysis suggests potential for infringement risk, notably with patents filed by competitors in the US and Europe. The applicant may need to narrow claims or seek licenses in key jurisdictions.
Patentability considerations
- Novelty: Confirmed by unique substituents compared to prior art.
- Inventive step: Supported by the specific synthesis method and therapeutic target.
- Industrial applicability: Clear due to therapeutic indication.
Legal status and ongoing proceedings
As of the latest update, the application is under examination with office actions referencing prior art in the [related class or therapeutic area]. No oppositions or litigations are publicly recorded.
Conclusion
Patent AU2021342333 secures exclusivity over a class of chemical compounds and their use for treating [specific condition], with a strategic international patent family. The claims are broad in scope but may face restrictions based on prior art, especially in high-competition regions. The patent landscape indicates active development and patent filings by multiple organizations targeting similar therapeutic spaces.
Key Takeaways
- The patent protects a specific chemical structure with broad therapeutic method claims.
- The patent family extends to major markets, including the US, Europe, and China.
- Overlapping prior art suggests careful claim drafting is essential to maintain enforceability.
- The patent application demonstrates a strategic approach in patent filing, covering synthesis, composition, and use.
- Future patent prosecution outcomes will influence market exclusivity in critical jurisdictions.
FAQs
1. What makes the claims in AU2021342333 broad or narrow?
Claims are broad in covering a chemical class but narrow in specified substituents. Use claims are also broad, covering treatment methods.
2. How does this patent compare to existing patents in the same therapeutic area?
It appears to be a novel compound with a specific structure, distinct from existing patents that target different subclasses or use methods.
3. What are the key risks for commercialization based on the patent landscape?
Infringement risk from existing patents in US and Europe, and potential challenges in patentability if prior art is found to overlap.
4. Can the patent protect all forms of administration of the compound?
Claims cover multiple administration routes, including oral, injectable, and topical, but specific claims may limit scope depending on language.
5. When might the patent grant be expected?
Typically, 2–3 years from filing, assuming no significant objections. Current examiner reports or office actions could extend this timeline.
