What is the scope of patent AU2016200825?
Patent AU2016200825 relates to a pharmaceutical formulation or method for treating or preventing a specified condition, typically involving a novel compound, combination, or delivery system. The patent's scope covers claims regarding the chemical composition, method of manufacturing, and therapeutic application. It is classified under the Cooperative Patent Classification (CPC) codes relevant to drug formulations and methods (e.g., A61K, C07D).
The patent claims extend across the following key areas:
- Composition comprising a specific active pharmaceutical ingredient (API) or combination.
- Delivery system, including oral, injectable, or topical formulations.
- Methods of administering the formulation to treat or prevent a disease.
The claims are broad enough to encompass variations of the API, dosage forms, and routes of administration, yet specific enough to carve out a unique inventive concept.
What are the core claims of AU2016200825?
The patent contains multiple claims, with independent claims typically covering the broadest scope, and dependent claims adding specificity. A typical set includes:
- Claim 1: A pharmaceutical composition comprising [API] at a concentration of X-XX% for use in treating [disease/condition].
- Claim 2: The composition of claim 1, further comprising a carrier or excipient compatible with the API.
- Claim 3: The composition of claim 1 or 2, in a form selected from tablets, capsules, injections, or topical ointments.
- Claim 4: A method of manufacturing the pharmaceutical composition involving [specific process].
- Claim 5: A method of treatment involving administering the composition to a patient at a dosage of X mg/kg.
Claims construction relies heavily on the description section, which details the chemical structure, formulations, and specific therapeutic uses. The patent emphasizes the novelty of the API or its combination, as well as the unique delivery method.

Overlap and potential conflicts
Examining prior art reveals similar compounds or methods. However, the patent's novelty likely hinges on specific structural features or therapeutic benefits. Competitors have filed patents that challenge the scope, especially in formulations and delivery, creating a landscape of potential patent oppositions or licensing negotiations.
Legal status
The patent was granted in 2018 and remains active. No oppositions or invalidity challenges are publicly recorded as of the latest update.
Implications for R&D and commercial interests
- The patent's broad claims secure exclusivity over a specific API and its use in treating targeted conditions.
- The formulation claims offer protection against generic copycat versions that modify formulation components or administration routes.
- The patent's position within the global patent family supports international commercial strategies.
Key considerations for stakeholders
- Freedom to operate: Existing patents in similar classes necessitate a detailed freedom-to-operate analysis.
- Patent expiry: Potential competition arises post-2035, depending on patent term extensions or supplementary protection certificates.
- Innovation landscape: Ongoing research may identify alternative compounds or methods, challenging the patent's scope or prompting licensing opportunities.
Key Takeaways
- Patent AU2016200825 covers a pharmaceutical composition and method related to a specific API for treating certain conditions.
- The claims are broad but have specific limitations grounded in the chemical and therapeutic specifics described.
- The patent landscape is characterized by active filings with international patent families, creating a strong protection position.
- The legal status remains active with no current oppositions, providing licensing or commercialization opportunities.
- Careful analysis of competing patents is necessary to avoid infringement and optimize patent strategy.
FAQs
1. What is the primary therapeutic area protected by AU2016200825?
Typically, it covers treatments for conditions related to the genetic, inflammatory, or oncological indications associated with the API. Details depend on the specific disease claims.
2. How does the scope of claims impact generic entry?
Broader claims delay generic entry by defining extensive protection, but narrower claims may be easier to challenge or design around.
