• Filter by International Patent Classification (IPC) codes pertinent to pharmaceuticals (e.g., A61K) and chemical subclasses.

Patent Life and Filing Date Impact

• The patent AU2018259089 was filed around 2018, based on typical 20-year patent durations originating from the filing date.
• Expected expiry around 2038 unless extensions or pediatric rights are granted.

Specific Legal and Technical Considerations

• Novelty and Inventive Step:

  • The patent claims appear to emphasize structural novelty over prior art.
  • The inventive step may hinge on unique substitutions leading to enhanced therapeutic efficacy or synthesis efficiency.

• Patentable Subject Matter:

  • Australian patent law safeguards chemical compounds, methods of manufacture, and use claims, provided they meet novelty, inventive step, and utility criteria.

• Potential Challenges:

  • Prior art disclosures might include similar compounds or methods, risking validity.
  • Overly broad claims could be susceptible to invalidation if they encompass known compounds.
