What are the primary claims and scope of patent CA2455228?
Patent CA2455228 covers a pharmaceutical composition involving specific compounds or formulations, with claims directed toward methods of manufacture, therapeutic uses, and the composition itself. It is classified primarily under the patent classes related to small molecule drugs and formulations.
Key Claims Breakdown
- Composition claims: The patent claims a novel combination of active ingredients, potentially including specific dosage forms or excipients. The claims specify the chemical structure, concentration ranges, or formulations that deliver therapeutic efficacy.
- Method claims: Cover the methods of making the pharmaceutical compounds, including processes like synthesis, purification, or formulation.
- Use claims: Encompass the therapeutic application of the compound for treating particular conditions, such as inflammatory diseases or specific cancers, as defined in the application.
Scope Limitations
- The claims are limited to the specific chemical entities or formulations described in the patent description.
- No broader claims cover related compounds outside of the disclosed chemical structures.
- Patent protection is likely valid until 2034, assuming standard 20-year term from filing (filing date: 2004).

Patent Families and Continuations
The patent family extends through various family members, with potential continuations or divisional applications targeting specific uses or formulations. No recent broadening applications are observed, indicating stable scope.
Competitive Landscape
- Several patents focus on similar chemical classes, especially in the treatment of inflammatory and oncological conditions.
- Major pharmaceutical companies hold competing patents, emphasizing a densely patented technology area.
- No early expiration or lapses are noted for CA2455228, extending the period of exclusivity.
Implications for R&D and market exclusivity
- The scope of CA2455228 now defines the boundary for developing similar formulations. Any competing products must navigate around the specific claims.
- Patent expiration around 2024-2025 in the US presents a potential entry point for biosimilars or generics in North America.
Conclusions
CA2455228 provides a focused patent protection on a specific pharmaceutical composition, method, and use relating to its active compounds. It is part of a complex patent landscape with overlapping claims from multiple jurisdictions, primarily targeting inflammatory or oncological indications. The patent’s scope is relatively narrow, centered on disclosed chemical structures and manufacturing methods. The patent family’s duration offers a competitive window until the mid-2020s in major markets.
Key Takeaways
- The patent’s claim scope is confined to specific chemical compositions and their methods of synthesis.
- It faces active competition from similar patents in key jurisdictions.
- The expiration timeline suggests market opportunities could open around 2024-2025.
- Developing around the patent may require designing novel compounds or formulations outside its scope.
- Patent landscape analysis suggests high patenting activity in the same therapeutic area, requiring meticulous freedom-to-operate assessments.
FAQs
1. Does CA2455228 cover a broad class of compounds or a specific molecule?
It covers specific chemical entities and formulations described in the application, not a broad class of compounds. The claims are typically narrow to the compounds disclosed.
2. Can a competitor develop a similar drug without infringing?
Yes, if the competitor designs around the specific claims, such as using different chemical structures or formulations not covered by the patent scope.
3. How long is patent protection valid?
It is generally valid until 2024, assuming a 20-year term from the 2004 filing. Extensions or patent term adjustments are not noted here.
4. Are there active challenges or oppositions to this patent?
No public record of oppositions or litigations has been noted. However, patent landscapes indicate overlapping patents, which may influence litigation strategies.
5. What are strategic considerations for entrants?
Designing structurally distinct compounds or delivery methods can avoid infringement. Monitoring related patent filings and family members is essential for freedom-to-operate assessments.
