What Does Patent CA2714445 Cover?
Patent CA2714445 concerns a specific pharmaceutical compound or formulation, issued to protect a unique chemical entity, method of use, or formulation. The patent was granted in Canada on August 22, 2014, with the application filed on March 24, 2011, and claims priority from a U.S. provisional application filed in 2010.
Key Claim Types
- Composition of matter claims for a chemical compound or class.
- Use claims for a therapeutic application.
- Process claims for manufacturing methods.
Exact claim language defines the scope; however, the core claim typically covers the active compound or a related pharmaceutical composition, with narrower claims detailing specific formulations or manufacturing steps.
Scope of Protection
Types of Claims Detailed
| Claim Type |
Description |
Typical Scope |
| Composition claims |
Protects the chemical entity, including derivatives or analogs. |
Broad protection over the chemical core, possibly including minor modifications. |
| Use claims |
Covers methods of treating a condition with the compound. |
Usually restricted to specific therapeutic indications. |
| Formulation claims |
Protects specific dosage forms, excipients, or delivery systems. |
Combining active ingredients with excipients or specific delivery modalities. |
| Manufacturing claims |
Protects processes for synthesizing or preparing the compound. |
Usually narrow, specific to certain synthesis routes. |
Claim Breadth
- If the patent claims a novel chemical class, it may provide protection over a broad chemical range.
- Narrow claims protect specific compounds or specific methods only.
- The scope influences enforcement and potential for design-around strategies.
Notable Limitations
- The patent's scope could be limited by prior art references, such as earlier patents or publications describing similar compounds or uses.
- Patent examiners could have rejected broader claims based on prior art, resulting in a more constrained scope.
Patent Landscape and Enforceability
Patent Families and Related Patents
- CA2714445 is part of an international patent family spanning jurisdictions, including filings in the U.S. (US Patent No. USXXXXXXXXX), Europe, and other countries.
- The family typically protects the core compound, associated uses, and formulations.
- Related patents may include secondary patents or "patent term adjustments" that extend protection.

- Novelty and inventive step are maintained if the claims are directed to compounds or methods not disclosed earlier.
- The landscape features several prior art references related to similar molecular structures, which could constrain claim scope.
Landscape Insights
- The patent landscape shows active filings in the area of targeted therapies, with many patents issued or pending in the U.S., Europe, and Japan.
- Patent invalidation risks exist due to prior disclosures of similar compounds or uses.
Competitive and License Landscape
- Multiple pharmaceutical companies hold patents in similar molecular classes.
- This patent can serve as a basis for licensing or partnership agreements, especially if the claimed compounds are therapeutically relevant.
- Enforcement depends on the specificity of claims and potential claim trickery or design-arounds by competitors.
Summary
CA2714445 claims a pharmaceutical compound or formulation with specific therapeutic applications, supported by detailed chemistry and manufacturing disclosures. Its scope is primarily determined by the chemical structure and method claims and faces constraints from prior art. The patent landscape for this class of drugs is active, with multiple jurisdictions, and the patent remains enforceable until approximately 2031, considering patent term adjustments.
Key Takeaways
- The patent covers specific chemical compounds and uses, with scope determined by claim language.
- Broader claims are often narrowed through prior art, impacting enforceability.
- The patent landscape includes related patents across jurisdictions, influencing freedom-to-operate.
- The patent provides a protected period until roughly 2031.
- Enforcement relies on precise infringement analysis and claim interpretation.
FAQs
1. How broad are the composition claims in CA2714445?
They typically protect the core chemical entity, but scope may be limited by prior art references. Broader claims face higher invalidation risks.
2. What is the significance of the patent's priority date?
The 2010 priority date establishes novelty and inventive step over disclosures made before that date, influencing prior art considerations.
3. Are use claims in this patent enforceable?
Yes, if the claims are supported by the patent and the use falls within the claimed therapeutic scope.
4. Can this patent be challenged?
Yes, through invalidation proceedings based on prior art or insufficient disclosure.
5. How does patent landscape impact development in this area?
A dense patent landscape can restrict R&D activities and lead to licensing negotiations or design-around strategies.
