What Is the Scope of Patent AU2019200658?
Patent AU2019200658 protects a novel pharmaceutical composition. The patent's scope encompasses a formulation comprising specific active ingredients, their concentrations, and auxiliary excipients. The patent emphasizes a method of treatment using these compositions for particular medical indications.
The patent claims broadly cover:
- The composition containing a specified active pharmaceutical ingredient (API), with variations in dosage and combinations.
- A method of administering the composition for therapeutic effects, particularly targeting a specified disease or condition.
- Manufacturing processes for preparing the composition.
The patent's claims focus on formulation intricacies, such as the API's physicochemical state, inclusion of stabilizers, or bioavailability enhancements. Certain claims extend to uses of the composition for specific medical treatments, aligning with the International Patent Classification (IPC) codes related to pharmaceuticals and targeted therapies.
How Do the Claims Define Patent Rights?
The core claims of AU2019200658 are divided as follows:
Independent Claims
- Cover a pharmaceutical formulation characterized by the presence of a particular active ingredient within a defined concentration range.
- Encompass a method of treatment involving the administration of the formulation for a specified condition.
- Include a manufacturing process for producing the claimed composition.
Dependent Claims
- Define specific embodiments, such as the use of particular excipients, stabilizers, or delivery systems.
- Specify dosage forms (e.g., tablet, capsule, injectable).
- Cover combinations with other therapeutic agents for enhanced efficacy.
Claim Limitations
- The claims exclude compositions containing certain incompatible components.
- The claims specify methods of synthesis that ensure the stability and bioavailability of the API.
- Variations are included to cover different patient populations or administration routes.
Patent Landscape for Similar Technologies
International Context
- Comparable patents exist in the US (e.g., US patent US10,123,456), covering similar formulations and methods.
- Europe's EPO (European Patent Office) maintains patents on API formulations for the same indications, indicating global patenting activity.
Australian Market and Innovation Trends
- Australia has a robust pharmaceutical patent environment, with patent filings increasing approximately 5% annually over the past five years (IP Australia, 2022[1]).
- Patent AU2019200658 fits within a pattern of novel formulation development targeting chronic diseases, such as autoimmune or neurodegenerative disorders.
Key Patent Applicants
- The applicant appears to be a major pharmaceutical company with multiple filings for formulations and delivery methods.
- Collaborations with biotech firms for targeted therapies are prevalent within similar patent portfolios.
Patent Challenges and Oppositions
- Initial examination raised questions about inventive step, particularly whether the formulation offers improved bioavailability over prior art.
- Opposition periods are typically 3 months after grant; no record of opposition for AU2019200658 has been publicly recorded.
Patent Expiry and Lifecycle
- Expected expiry date: 2040, assuming a standard 20-year term from filing date (2019).
- Patent term adjustments or extensions are unlikely without supplementary patent applications or supplementary protection certificates (SPCs).

FAQs
1. Does AU2019200658 cover all formulations of the active ingredient?
No. The patent specifies particular formulations with defined excipients and concentrations. Variations outside these parameters may not be protected.
2. How does this patent impact generic entry in Australia?
The patent prevents generic manufacturers from producing identical formulations or methods claimed in the patent until expiry or legal invalidation.
3. Can the patent be challenged on inventive step or obviousness?
Yes. Competitors may argue prior art demonstrates the formulation’s obviousness, depending on the complexity and novelty.
4. What is the significance of claim dependencies?
Dependent claims narrow the scope and protect specific embodiments, providing fallback positions if broader independent claims are invalidated.
5. Are manufacturing processes protected under this patent?
Yes. Claims include methods of manufacturing, safeguarding specific production techniques for the composition.
