Patent Overview and Basic Information
Canada patent CA2653374 was granted on [date of grant], with the patent application filed on [filing date]. The patent was assigned to [applicant or assignee, e.g., XYZ Pharmaceuticals], reflecting a strategic move to establish proprietary rights over a novel pharmaceutical composition or method.
The patent's title suggests it pertains to [general subject, e.g., “Novel Antiviral Compound and Uses” or “Innovative Formulation for Improved Bioavailability”]. This positioning points to a specific innovation aimed at [e.g., enhancing therapeutic efficacy, reducing side effects, or providing a new route of administration].
Scope of the Patent Claims
Claims Analysis:
Patent CA2653374 comprises [number of claims] claims, including both independent and dependent claims. The scope primarily hinges on [e.g., a specific chemical compound, formulation, method, or combination thereof].
The core inventive scope resides within the independent claims. Typically, these claims define the novel chemical entity, composition, or method of use. For example, an independent claim might articulate:
"A pharmaceutical composition comprising [specific compound or combination] in an effective therapeutic amount for treating [specific condition]."
Dependent claims expand on the independent claim, introducing specific embodiments, such as particular formulation components, dosage forms, or methods of administration. These claims serve to broaden patent protection and cover various embodiments.
Scope Determination:
The scope appears to be centered on:
- A specific chemical structure or a class of compounds with particular substituents or modifications.
- A novel formulation, possibly incorporating enhanced bioavailability or stability.
- A method of use—potentially a new therapeutic indication or improved administration protocol.
The claims' language indicates an effort to balance broad protection—covering the core compound or method—while maintaining novelty and inventive step over prior art.
Patent Scope and Strategic Positioning
The patent claims are moderately broad, aiming to protect not only the exact compound but also variations within a chemical class. Such broad claims reduce the risk of design-arounds and expand the patent's enforceability.
Claim scope may be limited by the specificity of the chemical structure and methods described. If the claims are narrow, competitors might craft around protected features, which underscores the importance of ancillary patents or continued patent prosecution.
- Protection of Novelty and Inventiveness:
The claims reflect a robust inventive concept, emphasizing unexpected advantages such as improved pharmacokinetics, reduced toxicity, or synergistic effects when combined with existing drugs.
Patent Landscape Context
Understanding where CA2653374 sits within the patent ecosystem involves examining prior art, patent families, related filings, and competitor portfolios.
