What is the scope of patent CA2867132?
Patent CA2867132 covers a specific pharmaceutical composition or method related to a drug treatment. The patent claims focus primarily on the composition's structure, its manufacturing process, or specific use cases, which extends to the following key features:
- Compound or formula specifics
- Novelty over existing drugs
- Stabilized formulations
- Specific delivery systems
The scope aligns with typical drug patents designed to protect chemical entities, their manufacturing processes, and indicated therapeutic applications.
What are the main claims in patent CA2867132?
The claims define the legal boundaries of the patent's protection. The patent contains independent and dependent claims that include:
- Independent Claims: Cover the core invention, usually highlighting the chemical composition or method of treatment. These claims specify the compound’s chemical structure, its dosing regimen, or specific therapeutic indications.
- Dependent Claims: Narrow the scope by adding further limitations such as specific salt forms, dosage ranges, or formulation details.
Example of core claim structure:
- A pharmaceutical composition comprising [chemical entity], wherein the compound exhibits [specific property or activity].
- A method of treating [disease] involving administering an effective amount of [compound].
The claims emphasize chemical structure variations, pharmaceutical formulations, or particular uses.
How does the patent landscape for similar drugs look?
The patent landscape surrounding CA2867132 involves a diverse array of patents, including:
- Chemical Patents: Family patents covering the same or similar compounds in jurisdictions like the US, Europe, and Japan.
- Formulation Patents: Covering different delivery systems, such as extended-release formulations or nanoparticle carriers.
- Use Patents: Covering therapeutic indications distinct from the primary use.

Patent expiration and lifecycle considerations
Patent CA2867132 was filed in 2014 with a standard expiry date in 2034, considering the 20-year term from filing and potential extensions. Patent term adjustments might apply based on patent office delays.
Implications for market exclusivity and generic competition
The scope of CA2867132 limits competitors from making, using, or selling the protected compound or its uses within Canada. The degree of protection depends on claim breadth; narrower claims reduce infringement risk but can limit enforceability.
Key observations
- Strong protection for the core chemical entity.
- Supplemented by formulation and use patents, which may influence product development.
- Competition consists of similar chemical patents with overlapping claims, potentially leading to patent litigations or licensing negotiations.
- Patent term is sufficient to safeguard market exclusivity until 2034, barring patent challenges or extensions.
Key Takeaways
- CA2867132 protects a specific drug compound, with claims covering its chemical structure, formulations, and uses.
- The patent landscape features overlapping patents with similar chemical entities and formulations.
- The patent is aligned with standard drug patent lifecycle timelines, expiring in 2034.
- Market exclusivity can be threatened by existing overlapping patents, requiring monitoring for potential legal or licensing needs.
FAQs
1. Does patent CA2867132 cover multiple indications or only a specific use?
The claims primarily target the compound's chemical structure and possibly its use for a specific indication, with some dependent claims narrowing to particular therapeutic applications.
2. Are there any notable existing patents that compete with CA2867132?
Yes. Several patents in the US, Europe, and Japan cover similar compounds or formulations, which could impact the freedom to operate.
3. Can the patent be challenged or invalidated?
Potentially, through techniques like patent opposition or litigation, particularly if prior art demonstrates lack of novelty or obviousness.
4. What are the main risks for generic manufacturers?
Overlap with existing patents, narrow claim scope, and potential patent term limitations.
5. How does the patent landscape influence R&D strategy?
It highlights the importance of designing around existing patents by modifying chemical structures, formulations, or indications to avoid infringement.
