Overview of Patent WO2017214367
Filing & Publication Details:
Patent WO2017214367 was published by WIPO in 2017. The application number indicates international filing under the Patent Cooperation Treaty (PCT), providing the applicant a unified route to patent protection across multiple jurisdictions.
Invention Summary:
The patent covers a novel class of compounds with specific pharmacological activity, purportedly targeting a biological pathway relevant to a medical condition such as neurodegeneration, oncology, or infectious disease. The application claims both the chemical entities and their pharmaceutical formulations, with an emphasis on increased efficacy, reduced toxicity, or improved bioavailability.
Scope of the Patent: Technical and Legal Analysis
Core Technical Disclosure
The patent claims a novel chemical structure, described as a [placeholder for chemical class, e.g., quinoline derivative], with specific substituents designed to enhance binding affinity to [relevant biological target, e.g., kinase, receptor]. It discloses synthesis methods, related intermediate compounds, and pharmaceutical compositions suitable for administration.
Claims Structure
The patent’s claims define the legal scope. They typically include:
-
Claim 1 (Compound Claim):
Defines the chemical structure broadly, often including Markush groups for substituents, ensuring broad coverage over similar derivatives.
Example: “A compound of the formula I, or a pharmaceutically acceptable salt or ester thereof, wherein R1, R2, etc., are as described.”
-
Dependent Claims:
Narrow the scope to specific substituents, stereochemistry, or optimized formulations. These provide fallback positions if broader claims face invalidation.
-
Method Claims:
Cover synthesis processes, methods of use, or therapeutic methods involving the compounds.
-
Formulation Claims:
Define pharmaceutical preparations containing the claimed compounds with excipients and delivery modes.
Legal Scope & Potential Challenges
Given the typical breadth of chemical compound claims, the patent’s enforceability hinges on:
