What is the scope of AU2019250179?
Patent AU2019250179 covers a pharmaceutical invention relating to novel compounds, formulations, or methods for treating specific medical conditions. The patent's scope focuses primarily on chemical entities or therapeutic uses, with broad claims intended to secure patent rights across multiple applications in the field.
The patent claims encompass:
- Novel chemical structures or derivatives with specific pharmacological activity.
- Methods of synthesizing these compounds.
- Therapeutic methods involving these compounds for treating certain diseases, likely including or focusing on cancers or chronic conditions based on similar prior art.
- Pharmaceutical formulations containing these compounds.
The patent's claims are structured to protect both the compounds themselves and their use in therapy, aligning with typical pharmaceutical patent strategies to secure market exclusivity.
How are the claims structured?
The patent includes:
- Independent claims that define compound structures using chemical formulae, with specific structural features and substituents.
- Dependent claims that specify particular variations or embodiments of the independent claims.
- Use claims that cover methods of treatment using the compounds.
The chemical claims feature Markush groups, providing a broad scope of chemical variants. Use claims specify administration routes, dosages, or therapy conditions to expand patent coverage to various therapeutic scenarios.
What are the key claims?
-
Compound Claims: Cover chemical entities with defined core structures and functional groups, potentially including salts, solvates, and esters, depending on the claim set.
-
Method Claims: Cover methods of preparing the compounds and methods of using the compounds for therapeutic purposes.
-
Formulation Claims: Cover pharmaceutical compositions comprising the claimed compounds with inert carriers or excipients.
The claims aim to protect not only the core chemical compounds but also their uses and formulations, typical in patent strategies for pharmaceutical innovations.
