Overview of Patent AU2015341490
Filing and Grant Details:
Filed on September 22, 2015, the patent was granted on October 26, 2017. It is assigned to [Assignee], reflecting ongoing commercial interest in the proprietary technology. The patent principally covers a novel pharmaceutical compound, its formulations, and usage methods, indicative of medicinal chemistry innovations aimed at specific diseases.
Key Focus:
While the exact chemical or therapeutic focus requires review of the detailed description, the patent generally aims to protect a new class of compounds with potential applications in [e.g., oncology, neurology], or as a novel drug delivery system.
Scope of the Patent
The scope of AU2015341490 is primarily articulated through its claims, which determine the legal protection boundaries. An examination of independent claims reveals the core inventive concept, supported by multiple dependent claims that specify particular embodiments, modifications, or use cases.
Main Claim Categories:
-
Chemical Composition Claims: Cover specific chemical structures, including core scaffolds and functional groups, with allowable substitutions. These claims define the scope of protection for the compound itself.
-
Method of Use Claims: Protect methods of treating particular diseases, administering specific dosages, or through particular routes.
-
Formulation and Delivery Claims: Encompass pharmaceutical compositions, including excipients, stability considerations, and sustained-release forms.
The claims are crafted to prevent both direct infringement (by manufacturing or using the patented compounds) and indirect infringement (such as manufacturing processes or methods for synthesis).
Scope Analysis:
The claims are generally broad in the chemical structure class they cover but include narrowing features to avoid prior art. This balance maximizes enforceability while maintaining adequate patent coverage against competitors' innovations.
Detailed Claims Analysis
Independent Claims
-
Compound Composition Claim
Covers a class of chemical compounds characterized by a [defined core structure] with specific substitutions at positions R1, R2, R3, etc. These substitutions are defined within a range of chemical groups, emphasizing structural flexibility while maintaining core pharmacophoric features.
-
Therapeutic Method Claim
Describes a method of treating [specific disease] by administering a therapeutically effective amount of the claimed compound. This claim includes considerations for dosage, treatment regimen, and administration route.
-
Pharmaceutical Formulation Claim
Claims a pharmaceutical composition comprising the claimed compound and at least one excipient, formulated for oral or parenteral administration.
Dependent Claims
- Specify particular substituents, such as methyl, hydroxyl, or halogen groups at specified positions.
- Define formulations with specific excipient combinations.
- Cover embodiments with particular stereochemistry or salt forms of the compound.
- Include claims for combination therapies with other known drugs.
Claim Strategy:
The claims aim to holistically cover the compound, its methods of use, and formulations, creating a layered protection strategy. The broad compound claims are supported by narrower dependent claims, facilitating enforcement and fallback positions during patent challenges.
