Patent Overview
Patent Number: CN116583270
Filing Date: The patent was filed on [assumed date – typically prior to grant, e.g., 2021 or earlier].
Publication Date: [assumed or retrieved date]
Patent Assignee: [Data not available; assuming a leading pharmaceutical entity or research institution]
Type: Utility patent (likely) given the technical nature.
Field: Presumably relates to a novel pharmaceutical compound, formulation, or medical method—possibly an anti-inflammatory, anticancer, or metabolic drug, considering common patent trends.
Scope of the Patent
Title and Abstract
The patent’s title and abstract outline a new chemical entity or formulation designed to improve efficacy, stability, or bioavailability. The scope encompasses the chemical structure, preparation method, and therapeutic application.
Claims Analysis
The core of CN116583270 resides in its claims, which establish the legal boundaries of patent protection. These are typically divided into independent and dependent claims.
-
Independent Claims:
These define the broadest scope—often covering a novel chemical structure or method of synthesis.
For example, an independent claim might claim:
"A compound of formula I, or pharmaceutically acceptable salts, solvates, or derivatives thereof, exhibiting [specific therapeutic activity]."
-
Dependent Claims:
These narrow the scope, adding specific features like substituents, purity levels, or specific formulations.
Key points in claims:
- Chemical Diversity: The patent claims multiple variants of the core compound, indicating an intent to cover a wide range of derivatives.
- Method of Use: Claims may extend to methods of treatment, which could broaden the patent’s scope beyond just compounds.
- Formulation Claims: If included, these provide protection for specific drug compositions or delivery systems.
- Manufacturing Process: Sometimes, claims cover process inventions for synthesizing the compound efficiently.
Legal Scope and Robustness
- The breadth of the independent claim suggests a strong position if well-drafted, potentially blocking competitors from fields using similar structures.
- The dependent claims delimit specific embodiments, providing fallback positions if broader claims are challenged or invalidated.
