What is the scope of patent AU2015222937?
Patent AU2015222937 pertains to a pharmaceutical invention, specifically a novel method or composition involving a drug compound. It addresses the formulation, combination, or administration technique related to the active ingredient. The patent claims protection over specific chemical entities, their pharmaceutical formulations, and associated methods of treatment.
The patent's scope encompasses:
- A particular chemical compound or a class of compounds.
- Pharmaceutical compositions incorporating the compounds.
- Methods for preparing or administering these compositions.
- Therapeutic applications targeting specific medical conditions.
The patent claims are drafted broadly to prevent competitors from developing similar formulations or alternative methods of delivery that could circumvent the patent.
How do the claims define the patent's coverage?
Overview of the Claims
The patent's claims are divided into independent and dependent claims:
- Independent claims specify the core invention, often incorporating the chemical entity or method at the broadest scope.
- Dependent claims narrow the scope, adding features such as specific dosage forms, combinations, or treatment parameters.
Key Claim Elements
- Chemical Composition or Compound: The primary claim covers a specific chemical structure or class. The claims include features such as molecular formulas, substituents, and stereochemistry.
- Pharmaceutical Formulation: Claims extend to pharmaceutical compositions comprising the active compound, excipients, carriers, and delivery mechanisms.
- Method of Treatment: Claims also protect methods of administering the compound to treat a specified condition, such as cancer, neurological disorders, or metabolic diseases.
Claim Limitations
- The claims specify concentrations, dosages, or frequency of administration.
- They include certain formulations like tablets, capsules, injections, or transdermal patches.
- The claims specify treatment protocols, such as dosage schedules or combination therapies.
Claim Breadth and Vulnerability
The scope's breadth balances broad composition or method claims with narrower dependent claims. Broad claims are vulnerable to validity challenges on grounds of novelty or inventive step if prior art references disclose similar compounds or methods.

Patent Family and Priority
The progenitor patent family includes filings in other jurisdictions, claiming priority from an initial application in 2014. The Australian patent filings align with global patent strategy targeting key markets for pharmaceutical development.
Patent Life and Expiry
- The patent was granted in 2015 with a typical term extending 20 years from the original filing date.
- The expected expiry date for AU2015222937 is around 2034, considering possible terminal extensions.
Patent Filing Trends
- The filed patents often include structural claims and methods of use.
- Recent filings tend to focus on novel formulations, delivery systems, or combination therapies.
- Patent owners continuously monitor prior art and competitors’ filings for invalidity and infringement risks.
What are the key legal considerations?
- Novelty: The patent claims must be distinct from prior art. Similar compounds or methods disclosed before 2014 could invalidate the patent.
- Inventive Step: The claimed invention must demonstrate inventive merit over existing compounds or treatments.
- Utility: The patent must specify a clear therapeutic application.
- Patentability Challenges: Competitors may challenge on grounds of obviousness, lack of inventive step, or insufficient disclosure.
Summary of the patent landscape
The patent landscape indicates a strategic global protection approach with filings in major pharmaceutical markets. The scope emphasizes chemical and therapeutic claims broad enough to cover various formulations and uses but sufficiently specific to withstand legal challenges.
Key Takeaways
- The scope of AU2015222937 broadly covers the specific chemical compounds, their formulations, and methods of treatment.
- Claims are designed to protect core compounds and their applications while balancing vulnerability to prior art.
- The patent landscape indicates active prosecution in Australia, the US, Europe, and China, aligning with global pharmaceutical patent strategies.
- Patent duration extends to approximately 2034, providing long-term market exclusivity.
- Legal considerations focus on novelty, inventive step, and utility to defend against patent challenges.
Frequently Asked Questions
1. How broad are the claims in AU2015222937?
They include specific chemical structures, formulations, and methods of treatment. The claims are sufficiently broad to cover variants but specific enough to avoid invalidation by prior art.
2. What is the typical lifespan of this patent?
The patent, granted in 2015, expires around 2034, assuming standard 20-year term with no extensions.
3. How does the patent landscape influence market exclusivity?
Multiple jurisdictions filing extend protection globally, reducing competitors' ability to introduce similar products during the patent term.
4. Can competitors develop similar compounds to circumvent the patent?
If they design structurally different compounds or alternative delivery methods not covered by claims, they may avoid infringement but face validity challenges.
5. Are there any known patent challenges to AU2015222937?
There are no public records of legal challenges or oppositions in Australia as of now but monitoring prior art references remains critical.
