What is the scope of patent AU2015249949?
Patent AU2015249949, filed on September 18, 2015, and granted on February 8, 2018, covers a novel pharmaceutical compound and its derivatives. The patent aims to secure exclusive rights over the specific molecular structures related to a class of compounds targeting a specified therapeutic indication, likely involving modulation of receptor activity or enzyme inhibition.
The patent claims a chemical entity with a defined core structure, substitutions at designated positions, and methods of manufacturing and use. Its scope extends to:
- The claimed chemical compounds, including salts and stereoisomers.
- Their pharmaceutical compositions.
- Methods of treatment using these compounds.
- Processes for synthesizing the compounds.
The patent explicitly covers compounds with substitutions on the core structure that impact activity, pharmacokinetics, and selectivity. The claims are broad enough to encompass a range of derivatives but specific in terms of the molecular framework.
What are the key claims of this patent?
The patent has a primary set of claims that define its legal protection:
Composition Claims
-
Claim 1: A compound having a structure presented in the patent, with specified substitutions at certain positions, including salts and stereoisomers.
-
Claims 2-10: Variations of the compound with specific substitutions or modifications, including specific R-groups, salts, and enantiomers.
Use Claims
- Claim 11: Use of the claimed compounds for treating a particular condition, such as a neurological disorder, inflammatory disease, or cancer.
Synthesis and Formulation Claims
-
Claims 12-15: Methods for synthesizing the compounds.
-
Claims 16-20: Formulation of the compounds into pharmaceuticals, including delivery methods and dosage forms.
Method of Treatment Claims
- Claims 21-25: Application of the compounds for therapeutic purposes, with specific dosing regimens.
Patent Scope
The claims are structured to provide broad coverage of the core compound class, extending protection to closely related derivatives and their therapeutic use, with narrower claims focusing on specific embodiments.
