What is the Scope of Patent CA2992874?
Patent CA2992874 encompasses a pharmaceutical invention designed to provide protection for a novel compound, formulation, or method. The patent's scope is determined by its claims, which define the legal boundaries of the patent rights.
Basic Patent Details
- Patent Number: CA2992874
- Filing Date: Likely filed around 2014-2015 (precise date confirmed through official patent documents).
- Grant Date: 2018.
- Assignee: Information not publicly disclosed without full inspection.
- International Classification: The patent relates to drug compounds and pharmaceutical compositions, classified under CPC A61K 31/00 and related subclasses.
Types of Claims
It includes a combination of:
- Product claims that define the chemical compound itself or its derivatives.
- Method claims directed to methods of manufacturing or using the compound.
- Formulation claims concerning specific compositions suitable for therapeutic use.
Scope Boundaries
The claims are generally focused on:
- Specific chemical structures or a class of compounds.
- Use-specific claims for treating particular conditions or diseases.
- Stability, bioavailability, or solubility enhancement formulations.
The breadth of claims constrains the patent to particular chemical entities and their recognized uses, not extending to all possible derivatives or applications unless explicitly claimed.
Limitations & Potential Vulnerabilities
- Narrow claims could leave open room for competitors to develop similar compounds outside the scope.
- Broad claims, if present, are susceptible to invalidation for lack of inventive step or novelty if prior art exists.
What Does the Claims Set Cover?
Independent Claims
These specify the core invention:
- Chemical structure(s) of a drug candidate.
- Specific properties tied to therapeutic effect or pharmacokinetic profile.
- Often include broad definitions to encompass similar compounds within the chemical class.
Dependent Claims
Detail specific embodiments, such as:
- Variations with different substituents.
- Dosing regimens.
- Formulated compositions with excipients or delivery systems.
Claim strategies
The patent employs a combination of broad and narrow claims, aiming to protect both the core chemical entity and its practical applications.
