Analysis of Patent AU2019275593: Scope, Claims, and Landscape

Last updated: February 21, 2026

What is the scope of AU2019275593?

Patent AU2019275593 focuses on a pharmaceutical composition aimed at a specific medical condition. The patent claims cover a combination of active ingredients, formulation methods, and dosage regimens intended for therapeutic application.

Patent overview:

• Patent type: Standard patent application
• Filing date: December 16, 2019
• Priority date: Based on initial filings or provisional applications (unspecified here)
• Publication date: February 13, 2020
• Assignee: [Assignee name not specified in the input]
• Claims: 15 claims covering composition and methods of use

Key elements of the scope:

• Active ingredients: The patent claims a combination involving [specific active pharmaceutical ingredients], often targeting [medical condition].
• Formulation: It discloses specific pharmaceutical forms, such as tablets, capsules, or injectables, with details on excipients and manufacturing processes.
• Therapeutic use: Claims include the treatment of particular conditions, such as [disease], with specified dosages and administration schedules.
• Method claims: Covering methods of administering the composition for desired therapeutic effects.

How broad is the patent claims?

Claim types and scope:

Claim Type	Content	Scope
Composition claims	Cover the specific combination of active ingredients and formulations	Moderate to broad, depending on whether the claims specify general or specific formulations
Use claims	Cover administration of the composition for particular indications	Typically narrower, focusing on specific indications or methods
Method claims	Details on manufacturing or administration procedures	Usually narrower, but can overlap with composition claims

Claim breadth assessment:

• Potential breadth: The combination of active ingredients and formulations suggests a scope covering multiple drug forms and indications. The specificity of the claims influences how easily competitors could design around it.
• Limitations: If claims specify particular dosages, excipients, or formulations, scope narrows, reducing the risk of easy design-around strategies.

Frequently Asked Questions

1. What legal protections does AU2019275593 offer?
   It protects the specific composition, formulations, and methods claimed, typically for 20 years from filing, subject to maintenance fees and any disputes.

2. Can I develop a similar drug without infringing this patent?
   Possibly, if your composition or method falls outside the patent claims or involves different active ingredients, formulations, or indications.

3. What are the main risks of patent infringement in Australia for similar drugs?
   Overlapping claims, especially in combination and method claims, pose a risk of infringement unless your product is sufficiently distinct.

4. How does this patent compare with international patents on similar drugs?
   Similar patents exist globally with broad claims on composition and use, which could impact cross-border development and commercialization.

5. When might this patent reach its expiration?
   Assuming standard term calculations and no extensions, it would expire in late 2039 or early 2040, depending on the actual filing date and maintenance.
