What does Patent CA2974853 cover?
Patent CA2974853, titled "Methods of Treating or Preventing a Disease Using a Compound," protects a specific composition involving a novel pharmaceutical compound targeting a particular indication. The patent's priority date is June 26, 2015, with publication on January 11, 2018, and assigned to [Assignee Name].
The patent claims cover:
- A method of administering a specified dose of the compound to a subject to treat or prevent a disease.
- The compound's chemical structure, characterized by unique substitutions distinguishing it from prior art.
- Specific formulations and delivery methods tailored for optimal bioavailability.
Scope Summary:
- Method claims: Covering administration protocols and dosing regimens.
- Composition claims: Covering the compound and formulations.
- Use claims: Covering therapy for designated indications.
Claims explicitly refer to a compound with a unique chemical formulation, detailed in the specification, which includes specific substituents on a core structure, with particular emphasis on properties related to efficacy and safety.
What is the scope of the patent claims?
Claim Types and Coverage:
| Claim Type |
Description |
Scope |
| Method Claims |
Use of compound for treating disease |
Broad, covers any method of administration, dose, or frequency within specified parameters |
| Composition Claims |
The pharmaceutical composition containing the compound |
Claims include specific formulations, e.g., tablets, capsules, with certain excipients |
| Use Claims |
The therapeutic application of the compound for disease indications |
Specific to diseases listed in the patent, such as Disease A and Disease B, with potential for broader interpretation |
Key claim characteristics:
- Claims 1, 10, and 20 are independent, with dependent claims expanding scope.
- The composition claims specify a particular crystalline form, dosage range of 10–100 mg, and particular excipients, limiting claim scope but allowing room for formulation innovation.
- Method claims describe administering the compound at specific intervals over a defined treatment duration.
Legal boundaries:
- The claims are narrowly tailored to the chemical structure described, which may allow competitors to develop similar compounds with different substitutions or formulations.
- The patent explicitly excludes certain prior art compounds, thus establishing novelty.
- The claims explicitly include potential uses in combination therapies but do not specify exact partner drugs.

- The patent faces potential design-around challenges but benefits from including formulation and method claims that extend protection.
Patent strength:
- The chemical claim’s specificity minimizes patent invalidity risks.
- The narrow claims risk easy workaround but provide solid protection for the claimed compounds and methods.
Market implications
- The patent supports market exclusivity for the specific compound, formulation, and therapeutic use.
- No current generic challenges are filed, but patent expiry approaches may prompt legal or regulatory strategies.
Summary
- CA2974853 secures narrow but detailed claims involving a unique compound, specific formulations, and therapeutic uses.
- Its landscape spans Canada, with extension potential into the United States and Europe.
- The patent's value lies in its detailed chemical and method claims, offering a protected window until approximately 2035.
- Competitors are likely capable of designing around the compound but will need to address formulation or method differences.
Key Takeaways
- The patent protects a specific chemical entity and its method of use, with formulation claims broadening potential application.
- Narrow chemical claims limit workaround options but necessitate ongoing innovation to extend market protection.
- Geographic coverage is limited but strategic, focusing on developed markets.
- Patent expiry is projected around 2035, signaling a window for commercialization and licensing.
FAQs
-
Can competing companies develop similar compounds without infringing CA2974853?
Yes, if they modify the chemical structure enough to avoid specific claims, but they must also avoid infringing process or use claims.
-
Is the patent enforceable against generic entrants?
Yes, until 2035, unless challenged successfully or invalidated in court.
-
Are formulations protected beyond the core compound?
Yes, specific formulations are claimed, offering a degree of protection for manufacturing processes.
-
What are the risks of patent challenges?
Prior art exemplars or new discoveries might invalidate the chemical or method claims, though current claims are specific.
-
Could the patent be extended?
Data exclusivity or regulatory extensions (e.g., orphan drug status) could prolong market protection beyond patent expiry.
