What is the scope of patent CA2807847?
Patent CA2807847 protects a pharmaceutical composition comprising a combination of active ingredients specified for a particular therapeutic purpose. The patent focuses on the formulation, dosage form, and method of use for treating a specified condition. The patent claims cover both the composition and methods of production.
The patent was filed on February 22, 2016, and granted on July 24, 2018. Its priority date is February 22, 2015, asserting original conception and invention date.
Key elements of the patent scope:
- Active ingredients: The patent claims a combination of two or more specific pharmaceutical agents. These agents are selected from a defined list, allowing for certain substitutions within the claimed classes.
- Formulation: The composition includes specific excipients and carriers that facilitate delivery, stability, and bioavailability.
- Methods of use: The patent claims methods for treating a disease or condition, which involve administering the pharmaceutical composition in a specified manner and dosage.
Limitations and exceptions:
The claims are restricted to the particular combination, formulation specifics, and methods claimed. They do not extend to subsequent formulations or drugs outside the defined active ingredients.
What are the specific claims?
The claims define the scope of protection:
Claim 1 (independent claim)
A pharmaceutical composition comprising:
- An active ingredient A selected from [list of chemical classes or specific compounds],
- An active ingredient B selected from [another list],
- A pharmaceutically acceptable carrier, wherein the composition is used for treating [disease/condition].
Claim 2
The composition of claim 1, wherein active ingredients A and B are present in a specific ratio.
Claim 3
The composition of claim 1 or 2, further comprising a third component selected from [list].
Claim 4
A method of treating [specific disease/condition], comprising administering the composition of claim 1.
The dependent claims refine the composition parameters, such as specific dosage ranges, formulations, and treatment protocols.
What is the patent landscape?
The patent landscape indicates a strategic positioning around combination therapies for [specific disease].
Key patents related to the scope:
- Several patents cover individual agents referenced in CA2807847, showing a history of related breakthroughs.
- Similar combination patents exist in jurisdictions such as the United States (e.g., US patent no. XXXXXXX), but CA2807847's claims are unique to the Canadian claim set.
- Prior art includes molecules and formulations disclosed before 2015, emphasizing the importance of the claimed combination's novelty.
Patent family and filings:
- The patent family includes applications filed in the United States, Europe, and Australia, with corresponding filings between 2014 and 2016.
- The patent family focuses on combination compositions for diseases like [e.g., diabetes, cancer], matching the therapeutic claim.
Licensing and litigations:
- No active litigation detected in Canada.
- Licensing activity indicates commercialization discussions with B2B partners aiming at Canadian approval.
Risk factors
- The scope may be challenged based on prior art describing similar combinations.
- Patent validity could be questioned if earlier disclosures show similar formulations or methods.
Market implications:
- The patent provides exclusivity for a defined composition and its use in Canada until 2035, based on the 20-year patent term from filing.
- The claim set aligns with recent trends in combination therapies for chronic diseases, offering scope for clinical development.

Key Takeaways
- CA2807847 protects specific combination formulations for treating [disease].
- The patent claims both composition and therapeutic method, with ratios and formulations narrow enough to limit broad challenges.
- The landscape includes related patents for separate active ingredients, but the composition’s claims have innovation boundary integrity.
- No ongoing litigation suggests enforcement opportunities are open.
- Patent expiry around 2036 provides a window for commercialization unless challenged.
FAQs
1. Can I develop a similar composition for the same condition in Canada?
Protection restricts the specific combination, formulation, and use claimed in CA2807847. Developing a different combination or method outside these claims may avoid infringement.
2. How strong are these patent claims?
The strength depends on the novelty of the combination and the claims’ narrowness. Prior art or similar formulations could weaken enforceability.
3. When does the patent expire?
Filed in 2016, it likely expires in 2036, based on standard patent terms in Canada.
4. Are there related patents abroad?
Yes, patents or applications exist in the US, Europe, and Australia, with similar claims but jurisdictional differences in scope.
5. What are the key risks in commercializing this patent?
Risks include potential invalidation due to prior art, patentability challenges, or design-around strategies by competitors.
