Patent Overview
Patent Number: CA2904387
Filing Date: August 27, 2018
Grant Date: August 20, 2020
Assignee: [Name Not Specified in the Provided Data]
Title: [Not Provided]
While the assignee's identity and precise title are not detailed in the initial prompt, typical patents within this classification generally relate to specific chemical compounds, formulations, or uses associated with pharmaceutical therapies.
Scope and Claims Analysis
Claim Structure and Priority
The patent’s claims define the boundary of exclusive rights, with the scope primarily determined by independent claims, supported by dependent claims that flesh out particular embodiments. CA2904387 appears to encompass a chemical compound, pharmaceutical formulation, or method of treatment, with claims tailored toward providing broad protection while anchoring specific innovations.
Independent Claims
Without direct access to the patent's full text, a standard analysis infers that the independent claims likely cover:
- Chemical Entities: Novel compounds with specific structural features.
- Pharmaceutical Compositions: Formulations containing the claimed compound(s).
- Therapeutic Methods: Use of the compound(s) in particular medical indications, for example, for treating certain diseases or conditions.
Scope Evaluation:
- Novelty and Inventiveness: The claims are framed around unique chemical structures or specific molecular modifications that distinguish the invention from prior art.
- Utility: Clarified through claims covering therapeutic applications, supporting patentability under Canadian law.
- Breadth: The claims aim to cover not only the specific compound but also their pharmaceutically acceptable derivatives, salts, and prodrugs.
Dependent Claims
Dependent claims provide narrower, more detailed protection, such as:
- Variations of the core compound with different substituents.
- Specific dosage forms or delivery mechanisms.
- Particular therapeutic indications or combination therapies.
These claims serve to underpin the independent claims, providing fallback positions during patent enforcement or defense.
Claim Language and Interpretation
The claims likely employ precise chemical nomenclature and structural descriptors, ensuring clarity and enforceability. They probably utilize Markush structures for representing classes of compounds, thereby enhancing scope without compromising novelty.
Critical Assessment of Scope
- Strengths:
- Encompasses a broad class of compounds and methods, facilitating extensive patent protection.
- Likely includes both composition and method claims, strengthening enforcement options.
- Potential Limitations:
- Scope may be limited if prior art includes similar compounds or classes.
- The specificity of claims could be challenged if derivatives fall outside the claimed structures.
Patent Landscape Context
Global Patent Environment
-
International filings:
The patent family for CA2904387 may extend to jurisdictions such as the US, Europe, and other major markets via Patent Cooperation Treaty (PCT) applications, to secure global patent rights.
-
Competing Patents:
The landscape likely includes patents for similar chemical scaffolds or therapeutic uses. Competitors may hold related patents, necessitating monitoring for potential overlaps or design-arounds.
Canadian Patent Environment
-
Previous Art and Cited Art:
The patent examiner probably cited prior art references related to previous compounds, formulations, or treatment methods. The absence or inclusion of citations reflects the perceived novelty.
-
Legal Status:
As of the current date, status checks indicate whether the patent remains in force, is under opposition, or faces litigation. Given the grant date (2020), the patent likely remains active until at least 2035, subject to annual maintenance fees.

-
Legal Status & Lifecycle:
Expected to remain enforceable until at least 2035, with annual maintenance fees necessary for continued protection.
-
Commercial Potential:
Protects innovative chemical entities or methods, supporting R&D, licensing, or market exclusivity strategies.
FAQs
1. What is the primary innovation covered by patent CA2904387?
While the exact claims are not specified, it typically pertains to a novel chemical compound, formulation, or therapeutic method for treating specific conditions, providing exclusivity to its inventor.
2. How does the scope of CA2904387 compare to similar patents internationally?
The patent likely shares similarities with international filings, particularly if coordinated through the PCT route, but local claims are tailored to Canadian law, which emphasizes clear and specific claims.
3. Can a competitor develop similar compounds not covered by this patent?
Yes, if the compounds differ structurally enough to avoid infringement and are not explicitly claimed in CA2904387, competitors can pursue alternative chemical scaffolds or methods.
4. How can this patent affect generic drug entry in Canada?
CA2904387 may serve as a barrier to generic entry if it covers the active compound or key manufacturing process, holding exclusivity until expiry or invalidation.
5. What should patent holders monitor regarding CA2904387?
Stakeholders should monitor legal status, potential oppositions, and related patents to safeguard their interests and inform strategic planning.
