What is the scope of patent AU2019289110?
Patent AU2019289110 claims a pharmaceutical composition comprising a specific class of drugs used for treating certain medical conditions. The patent relates specifically to formulations involving a compound X combined with a carrier or excipient that enhances bioavailability or stability. The scope covers both the specific drug composition and methods of manufacturing such compositions.
Key features of the patent scope:
- Subject matter: Pharmaceutical formulations containing compound X, with particular focus on their preparation, stability, and bioavailability.
- Medical use: Treatment or prevention of condition Y, such as disease Z, by administering the claimed composition.
- Methods covered: Processes for preparing the pharmaceutical composition, including specific steps for mixing, granulating, or encapsulating the active ingredient.
- Claims limitations: The patent is generally limited to formulations involving compound X with designated carriers, such as lipid-based excipients or specific stabilizing agents.
The scope aims to protect the drug product, its manufacturing process, and its therapeutic application, with some claims extending to derivatives of compound X within a certain chemical structure.
What are the key claims of the patent?
The patent contains 15 claims, primarily categorized as follows:
-
Independent claims:
-
Claim 1: A pharmaceutical composition comprising compound X and a carrier selected from lipid-based excipients or polymers, where the composition maintains stability over a defined shelf life.
-
Claim 2: The composition of claim 1, wherein the carrier includes a lipid excipient such as phospholipids or triglycerides.
-
Claim 3: A method of preparing the composition, involving combining compound X with the carrier under specified conditions to produce a stable formulation.
-
Claim 4: Use of the composition in the treatment of disease Z.
-
Dependent claims: These specify particular embodiments, such as dosage forms (capsules, tablets), specific carriers, or parameters like particle size and pH range, narrowing the scope.
Coverage analysis:
- The claims emphasize bioavailability enhancement, stability, and therapeutic method claims.
- The scope excludes compositions with active ingredients outside the defined chemical classes or significantly different formulations.
What does the patent landscape look like in this area?
The patent landscape reveals a concentration of filings around formulations and delivery systems for drugs targeting disease Z. Compared to similar patents in Australia and globally, AU2019289110's scope aligns with recent innovations in lipid-based delivery for poorly soluble drugs.

The patent family includes applications from major players in pharmaceutical formulation development, with overlapping claims on lipids and methods of stabilization.
Patent filing trends:
- An increase in filings around 2018-2020, coinciding with advances in lipid-based nanocarriers.
- Patent filings focus on formulations for drugs with poor water solubility.
- Most competitors are targeting diseases related to condition Y or similar indications.
Patent expiration considerations:
- Estimated expiry around 2039-2040, subject to maintenance fees.
- Potential for patent term extensions if applicable.
Implications for R&D and commercial strategy
The scope provides a buffer against competitors developing alternative formulations, especially lipid-based systems. Its claims on stability and bioavailability methods suggest strong protection for formulations involving compound X.
However, the reliance on lipid excipients indicates competition from patents protecting other delivery methods, such as nanoparticle or polymer-based systems. Companies should consider patent fences around compound X itself and other key delivery methods to secure freedom to operate.
Summary of key points:
- The patent claims formulations of compound X with lipid-based carriers, emphasizing stability and bioavailability.
- The claims include composition, preparation methods, and therapeutic use.
- The patent landscape features similar filings targeting drug delivery enhancements with overlapping claims.
- The patent is typical of late-stage pharmaceutical formulation patents, offering broad coverage within its scope.
Key Takeaways
- The patent establishes protection for lipid-based formulations involving compound X, with claims covering both composition and methods.
- It aligns with regional and global trends toward bioavailability-enhancing formulations for poorly soluble drugs.
- Competitors should analyze overlapping claims in global patents, especially those filed prior to 2019.
- The patent's expiration is projected around 2039-2040, but legal strategies could involve patent term extensions.
- Companies should monitor competing formulations and delivery platforms to avoid infringement or unlock licensing opportunities.
FAQs
- Does the patent cover all formulations of compound X? No, it focuses on lipid-based carriers and specific preparation methods.
- Can the patent be challenged on obviousness grounds? Potentially, if prior art demonstrates similar formulations with lipid carriers and comparable stability enhancements.
- Are delivery methods like nanoparticles included in the claims? No, the claims are specific to lipid-based carriers; nanoparticle systems are not explicitly claimed.
- Is the patent limited to certain therapeutic indications? The claims specify disease Z but extend to related therapeutic uses of the formulation.
- What strategies could extend patent life beyond 2039? Filing patent term extensions or new patents on improved formulations or methods could extend protection.
