Patent Coverage Summary:
- Patent Number: AU2015223072
- Filing Date: December 3, 2015
- Grant Date: October 20, 2016
- Priority Date: August 28, 2014 (from an earlier patent application)
- Expiration Date: December 3, 2035 (standard 20-year term, subject to maintenance)
The patent claims focus on methods of treatment, pharmaceutical compositions, and the chemical compounds themselves, which are likely small-molecule drugs. It potentially covers analogs, salts, and use in specific indications.
Geographic and Patent Family Context:
- The patent is part of a broader patent family filed in multiple jurisdictions; details likely include equivalents in the US, Europe, and other territories. The scope in Australia aligns with international patent strategies to secure market exclusivity.
What Do the Claims Cover?
Types of Claims:
- Compound Claims: Cover specific chemical entities or classes of compounds.
- Use Claims: Methods of treatment using the compounds for particular conditions.
- Formulation Claims: Pharmaceutical compositions and formulations.
- Process Claims: Manufacturing or synthesis methods.
Specific Aspects:
- The claims encompass compounds with particular structural features, such as substituents or backbone modifications.
- Claims extend to pharmaceutical preparations containing the compounds.
- Use claims specify treatment of diseases, potentially including neurological, oncological, or inflammatory conditions.
The broadest claims likely cover a chemical class, while narrower dependent claims specify particular substituents, formulations, or application methods.
Claim Scope Evaluation:
- The initial claims are probably broad, covering a chemical core.
- Dependent claims narrow coverage, adding embodiments or specific chemical variants.
- The scope's strength depends on the claim language, including whether it covers derivatives or is limited to specific compounds.

FAQs
1. Does this patent cover all possible derivatives of the compound?
No. The scope depends on claim language; typically, the broadest claims limit coverage to specific structures, with derivatives and analogs covered only if explicitly included.
2. Can competitors design around this patent?
Potentially, if they develop compounds outside the scope of the claims, such as different chemical classes or alternative mechanisms of action.
3. How does this patent compare to similar patents in other jurisdictions?
Its scope may vary; some jurisdictions allow broader or narrower claims depending on local patent laws, prior art, and prosecution strategies.
4. What are the main risks to the patent's validity?
Prior art, novelty, or inventive step challenges could threaten validity, particularly if earlier similar compounds or uses exist.
5. How long will this patent provide exclusivity?
Until December 2035, assuming maintenance fees are paid and no legal challenges invalidate the patent.
