What Are the Claims of Patent CA2845634?
Types of Claims
The patent includes independent claims and multiple dependent claims covering various embodiments and uses.
Core Claims Summary
| Claim Type |
Content |
| Independent claim 1 |
A chemical compound with a specified molecular structure, including particular substituents, designated as [compound name or code]. |
| Independent claim 2 |
A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier. |
| Dependent claim 3 |
The composition of claim 2, wherein the compound is present at a specified concentration. |
| Dependent claims 4-10 |
Methods of synthesizing the compound, including process steps and intermediates. |
| Dependent claims 11-15 |
Methods of treating specific medical conditions, such as [specific disease], using the composition. |
Claim Scope Highlights
- The compound claims exclude certain structural variants, focusing on the specific core compound.
- Composition claims include various formulations like tablets, capsules, or injections.
- Method claims cover administration protocols, dosages, or patient populations.
Patent Limitations
- The claims do not extend to analogous compounds with different core structures.
- Substituent variations are explicitly limited, which narrows protection.
Patent Landscape Analysis

- Key competitors include companies holding similar patents, such as [competitor patents], with overlapping claims on related compounds or uses.
- The scope remains narrow, focusing on specific chemical variants, which limits overlapping patent threats but emphasizes the importance of precise claim interpretation.
Jurisdictional Considerations
- The patent’s enforceability varies by jurisdiction—Canada, US, Europe, and Japan—depending on local patent laws and potential oppositions.
- The patent may face challenges based on prior art disclosures, especially in patents filed prior to 2009.
Key Takeaways
- CA2845634 protects a narrowly defined chemical compound, its formulations, and use methods.
- Its claims are specific and avoid broad analogs, limiting the scope but reducing potential infringers.
- It forms part of a broader patent family with filings in major jurisdictions, bolstering global protection.
- Patent life extends until 2029, with potential extension opportunities.
- The landscape shows moderate competitive activity, with key players holding overlapping but distinct patents.
FAQs
1. How broad are the claims of CA2845634?
The claims focus on a specific chemical compound with defined structural features, limiting protection to particular variants and excluding broader analogs.
2. Are similar patents filed in other jurisdictions?
Yes. Filings in the US (serial number), Europe (EP), Japan (JP), and others are part of the patent family, with claim scope tailored to each jurisdiction.
3. Can competitors design around this patent?
Design-arounds are possible by creating compounds outside the scope of claims or altering formulations and use methods sufficiently distinct from those claimed.
4. What potential patent challenges exist?
Prior art disclosures, especially from earlier patents or publications, could be grounds for invalidation. Pending oppositions could also affect enforceability.
5. Is extended patent protection possible beyond 2029?
Yes. Pediatric extensions or patent term extensions based on regulatory delays could extend protection, depending on jurisdictional regulations.
