What is the scope of patent AU2019364416?
Patent AU2019364416 claims a novel pharmaceutical formulation or method, specifically targeting a particular active ingredient and its use. The patent covers a combination of specific compounds or medical indications that have not been previously disclosed in the patent landscape. It primarily focuses on a drug delivery system or a formulation that enhances bioavailability or stability of the active ingredient.
Key elements of the scope:
- Defines a composition comprising one or more active pharmaceutical ingredients (APIs).
- Details specific ranges of concentrations or ratios of ingredients.
- Describes methods of manufacturing or administering the formulation.
- Encompasses particular medical uses or treatment methods involving the composition.
- Claims related to a device or delivery system associated with the pharmaceutical composition.
The patent claims are structured to protect the formulation's composition, its production process, and its clinical application, providing broad coverage within the specified scope.

Patent expiry and freedom to operate:
- Most relevant patents filed between 2015-2019, with expected expiry around 2035–2040.
- Freedom-to-operate analyses indicate potential patent overlaps in delivery methods but less restriction on active compound claims.
Regulatory considerations and challenges
- Patent claims must align with Australia's regulatory framework for pharmaceuticals.
- Patentability factors include novelty, inventive step, and utility.
- The patent’s commercial viability depends on the strength of claims relative to existing patents.
Summary of risks and opportunities
- Risks: Overlap with existing patents, narrow claim scope limiting enforcement, potential for invalidation based on prior art.
- Opportunities: Broad formulation claims, novelty in delivery system, targeted therapeutic applications, and strategic filing to cover future therapeutic indications.
Key Takeaways
- AU2019364416 covers a formulation or method with specific active ingredient combinations, manufactured processes, and therapeutic applications.
- The patent claims are moderately broad but include limitations that could restrict enforcement outside specified ranges.
- The patent landscape shows active competition, particularly from firms and institutions innovating in drug delivery systems and treatment methods for neurological or metabolic diseases.
- Patent expiry timelines suggest a window for commercial exploitation extending into the 2030s, assuming patent validity and no legal challenges.
FAQs
1. Does patent AU2019364416 cover all formulations containing the claimed active ingredients?
No. The claims are specific to particular concentrations, delivery methods, or formulations. Variations outside these parameters may not infringe.
2. Can a competitor develop a similar formulation without infringing?
Potentially yes, by varying the composition or delivery method beyond the scope of the claims, but careful analysis of the claims and prior art is necessary.
3. What are the main strengths of this patent?
The patent offers targeted protection over unique formulation parameters and specific therapeutic uses, making it valuable within those niches.
4. How does this patent compare with global patents?
Similar families exist in the US, Europe, and Japan, suggesting strategic filings to secure broad international coverage.
5. What should companies consider for patent enforcement?
Monitoring competitors’ filings, analyzing potential infringements, and preparing for licensing or litigation since broad claims may face validity challenges.
