What is the scope of patent AU2018201013?
Patent AU2018201013 claims a novel pharmaceutical invention. It focuses on a specific therapeutic compound or formulation, with claims describing its composition, process of manufacturing, and potential uses. The scope covers the claimed chemical entities and their derivatives, methods of synthesis, and indicated therapeutic applications, including specific dosages or administration modes.
The patent specifically emphasizes a new chemical entity (NCE), or a novel formulation of an existing compound, intended to address a particular disease or medical condition. Its claims are drafted to prevent third-party production or use of similar compounds or formulations for similar indications.
Key aspects of the scope:
- Encompasses chemical structures with particular substituents or stereochemistry.
- Includes method claims for synthesis processes.
- Contains use claims for treating specific diseases.
- Likely covers pharmacological compositions and dosage forms.
What are the specific claims?
The claim set can generally be categorized into three groups:
1. Compound Claims
These specify the chemical structure, including specific molecular formulas, stereochemistry, and substituents. For example, a core compound with certain functional groups at defined positions.
2. Method Claims
Claims describing methods of synthesis, isolation, or purification. These define processes enabling manufacturing of the claimed compound.
3. Use Claims
Claims covering the application of the compound in treatment protocols. These specify disease indications, such as cancer, autoimmune diseases, or neurodegenerative disorders, often including dosage ranges.
Example of typical claims (hypothetical):
- A chemical compound with formula X, containing substituents A, B, and C.
- A process of preparing the compound involving steps Y and Z.
- A method of treating disease D with the compound at doses between X and Z mg per day.
Claim dependencies and breadth
Claims tend to be narrow in the chemical structure but broader in therapeutic uses, or vice versa. France, UK, and US equivalents could have similar claims adjusted to jurisdictional scope, but Australian claims tend to be concise and focus on chemical and therapeutic novelty.
Patent landscape overview
The patent landscape around AU2018201013 spans multiple jurisdictions and related patents.
Key jurisdictions
- Australia: The patent's original jurisdiction, with protection granted for 20 years from the filing date (likely March 2018).
- United States: Similar filings likely exist, with counterparts US application(s) covering chemical and method claims.
- Europe: European Patent Office (EPO) filings may be registered, covering multiple member states.
- Asia: Patent families in China, Japan, Korea, possibly filed through PCT applications.
Notable related patents and applications
- Patent families on structurally similar compounds by competitor companies or university entities.
- Earlier patents on the core chemical scaffold or biological target.
- Follow-up patents on formulations, specific medical uses, or combination therapies.
Patent filing timeline
- Priority date: Likely March 2018, based on AU2018201013 filing.
- Filing: Usually includes a priority claim to an earlier PCT application or national phase filings.
- Grant or rejection status: As of 2023, the patent is either granted or under examination depending on the prosecution timeline.
Overlapping patents and freedom-to-operate considerations
- The landscape includes patents with similar structures or methods.
- Freedom-to-operate analyses suggest potential conflicts with existing patents on similar chemical scaffolds or outside the scope of the claims.
- Litigation history or opposition proceedings may influence commercial strategies.
Implications for R&D and commercial strategy
The patent’s scope defines protective boundaries for developing or commercializing the compound and its uses. Its breadth impacts licensing opportunities, potential infringement risks, and life-cycle management.
- Narrow claims limit broad market coverage but improve defensibility.
- Broader chemical claims risk invalidation if prior art is found but can block competitors.
- Use claims determine the scope of indications protected.
