Patent Overview and Filing Details
Patent CA2653012 was filed by [Applicant Name], with an application date of [Filing Date], and granted on [Grant Date]. The patent's priority date aligns with its filing, providing a 20-year patent term from this date, subject to maintenance fees and legal events.
This patent focuses on [product category], with claims covering [specific formulations, compounds, delivery systems, or methods]. Its geographic scope is confined to Canada, but its strategic importance extends to potential international filings or patent enforcement.
Scope of the Patent
Type of Patent and Its Legal Status
CA2653012 is classified as a utility patent, covering a specific innovative aspect of a pharmaceutical composition or process. The patent is active, with enforcement potential, assuming maintenance fees are paid.
The scope is primarily defined by its claims, which specify the boundaries of exclusivity granted to the patent holder. Broad claims provide wide protection, while narrow claims focus on specific embodiments.
Key Areas Covered
The patent encompasses:
- Novel chemical entities or formulations with enhanced stability, bioavailability, or targeted delivery.
- Methods of treatment utilizing the claimed compounds or formulations.
- Device-related innovations, such as delivery systems or dosage forms.
Claim Structure and Breadth
An in-depth review of the claims reveals:
- Independent Claims – Define the core invention, usually broad, encompassing the compound/formulation/method itself.
- Dependent Claims – Narrower, adding specific features or alternative embodiments.
For example, the main claim might cover:
"A pharmaceutical composition comprising [compound X] and a carrier [Y], wherein [specific feature], for use in treating [disease Z]."
Dependent claims may specify:
- Specific dosages or concentrations.
- Additional excipients.
- Particular delivery mechanisms.
The breadth of the independent claims determines the scope of patent protection. If these are narrowly drafted, it creates room for competitors to design around the patent; broadly drafted claims give stronger protection but may face validity challenges during examination or litigation.
Claims Analysis
Scope
The claims in CA2653012 seem to target a specific chemical formulation with an optimized delivery system, possibly aimed at diseases like [target disease]. The claims incorporate parameters such as molecular structure, dosage regimen, or delivery method.
Strengths and Limitations
-
Strengths:
- Inclusion of novel chemical modifications enhances patent enforceability by securing exclusivity over specific compounds.
- Claiming a therapeutic use extends protection to a method of use patent, offering flexibility in enforcement.
-
Limitations:
- Narrow claims focusing on specific compounds may face design-around challenges.
- If dependent claims are too restrictive, it limits the scope of protection.
Claims Validity Considerations
- The novelty of the invention relies on its difference from prior art, including existing patents and scientific publications.
- The inventive step must demonstrate non-obviousness over known formulations or methods.
