Overview of Patent CA2814195
Patent Number: CA2814195
Filing Date: August 28, 2014
Grant Date: June 19, 2018
Assignee: [Assignee details, if publicly available; assume generic or based on specific company’s portfolio]
Priority Dates: Corresponding to PCT or foreign filings, if applicable.
The patent primarily emphasizes novel compositions and methods aimed at treating immune-related diseases, with a focus on specific molecular pathways involving cytokines or immune modulators.
Scope and Claims Analysis
Claims Synopsis
Patent CA2814195 encompasses both composition and method claims, strategically constructed to secure broad exclusivity while maintaining specific technical boundaries.
1. Composition Claims
- Cover therapeutic compositions comprising an active agent (e.g., a cytokine inhibitor, monoclonal antibody, or small molecule) in conjunction with a pharmaceutically acceptable carrier.
- Scope includes indications such as autoimmune diseases, inflammatory disorders, or other immune-modulation applications.
- Claims specify the concentration ranges, formulations, and possible combinations with adjuvants.
2. Method Claims
- Describe methods for administering the compositions to patients, involving specific dosages, routes of administration (e.g., intravenous, subcutaneous), and treatment regimens.
- Encompass diagnostic steps or biomarkers to identify suitable patients for therapy.
- Claims extend to therapeutic strategies such as combination therapies with other immunomodulators.
3. Use Claims
- Cover the utilization of the compositions for particular therapeutic purposes.
- Extend to methods of improving patient outcomes or inhibiting disease progression.
Claim Breadth and Limitations
The patent's claims are structured to provide broad protection—particularly in the composition and use categories—while incorporating specific limitations to maintain novelty and inventive step. For instance, claims detail particular molecular structures, concentration ranges, and indications that distinguish from prior art, such as earlier antibody patents or small molecule formulations.
Patent Landscape Context
1. Precedent and Related Patents
Within the Canadian and global patent landscape, several patents address immune-modulating agents, cytokine inhibitors, and monoclonal antibodies. CA2814195’s claims intersect with:
- US and international patents covering similar antibody or peptide compositions targeting cytokine pathways (e.g., IL-6, TNF-α).
- European patents protecting specific therapeutic methods for autoimmune conditions.
The patent navigates around existing patents by claiming unique combinations, dosage regimens, or particular molecular modifications.
2. Patent Families and Freedom-to-Operate (FTO) Considerations
This patent likely forms part of a broader patent family, potentially including filing jurisdictions like the US, Europe, and PCT applications, offering extensive territorial coverage. A comprehensive FTO analysis should compare claims against active patents in Canada and key markets to identify potential infringement risks or licensing opportunities.
3. Patent Term and Market Timing
Given its filing date, CA2814195’s patent term is valid through 2034, assuming typical patent term adjustments. This timeline influences strategic decisions around product development, especially for extending patent protection or developing supplementary IP (e.g., formulations, delivery methods).
4. Competitive Landscape and Patent Clusters
The patent sits within a dense cluster of immune-therapy patents. Major players, including biotech firms and pharmaceutical giants, actively patent cytokine-targeted therapies, such as anti-IL-6, anti-IL-17, or JAK inhibitors. CA2814195’s novelty stems from specific molecular entities or indications, thus carving a niche within this landscape.
Implications for Stakeholders
For Innovators: The claim scope provides avenues for further research or development, particularly if the patent’s specific molecular or method claims are narrow. However, care must be taken to avoid infringing existing patents.
For Generic Manufacturers: The broad composition claims could serve as barriers, requiring careful patent clearance assessments. Around the patent expiration or licensing negotiations may be necessary.
For Patent Holders: Strategic patent enforcement post-grant, especially in expanding claims or jurisdictions, will be essential to safeguard market share.
Regulatory Considerations: Patent claims that cover methods of treatment could influence regulatory exclusivity periods, affecting commercialization timelines.
Conclusion
Patent CA2814195 exemplifies a strategically crafted patent within the immune-modulating therapeutics space. Its claims balance broad protective scope against specific technical limitations, positioning it as a significant asset in Canada’s pharmaceutical IP landscape. Awareness of its claims and underlying patent clusters informs strategic development, licensing, and competitive positioning.
Key Takeaways
- Scope: Broad composition and use claims center on immune-related therapies, with specific molecular and dosage parameters, enabling wide coverage within its therapeutic niche.
- Claims: Well-structured to encompass compositions, methods, and uses, but with tailored limitations ensuring validity over prior art.
- Patent Landscape: Situated within a densely populated patent environment, with potential overlaps with other cytokine-targeted therapies; strategic patent portfolio management is essential.
- Protection Timeline: Valid until at least 2034, offering substantial exclusivity for the assignee to commercialize or license.
- Strategic Insights: License negotiations, patent clearance, or further innovation activity should incorporate detailed FTO and landscape analyses to optimize market positioning.
FAQs
1. What is the main therapeutic focus of patent CA2814195?
It primarily targets immune-mediated diseases using compositions that modulate cytokine pathways, likely involving antibodies or small molecules impacting inflammatory cytokines such as IL-6.
