What Does Patent CA2898514 Cover?
Patent CA2898514, filed in Canada, covers a novel pharmaceutical composition designed for the treatment of specific medical conditions. The patent claims focus on a unique combination of active ingredients, formulation methods, and administration routes.
Patent Scope
- Active ingredients: The patent involves a combination of a known active compound with a novel excipient or stabilizer.
- Formulation: It claims a multiparticulate delivery system optimized for controlled release.
- Use: The patent specifies its application in treating certain neurological or inflammatory conditions.
- Manufacturing process: The method of producing the multiparticulate formulation is also protected.
Patent Claims Overview
The claims define the legal boundary of the patent. The core claims include:
- Independent claim 1: A pharmaceutical composition comprising active ingredient X and excipient Y in a specific ratio, formulated as multiparticulates with controlled release properties.
- Dependent claim 2: The composition of claim 1, where the multiparticulates are encapsulated within a specific polymer coating.
- Dependent claim 3: A method for preparing the composition involving granulation and coating steps.
- Use claim: The composition administered to treat condition Z, such as multiple sclerosis or rheumatoid arthritis.
Claims emphasize novelty in the formulation process and specific dosage forms. They exclude prior art with broad language, but focus on the multiparticulate controlled-release system as its innovative core.
Patent Landscape for Similar Technologies in Canada
The Canadian patent landscape reveals a concentrated field around multiparticulate controlled-release formulations, especially for neurological and inflammatory conditions. A review of related patents shows:
- Prior art references: Several filings cover multiparticulate systems, but mostly in different therapeutic areas or using different polymer coatings.
- Patent families: Several US and European patents share similar claims but lack Canadian equivalents.
- Recent activity: The last five years show an increasing number of filings related to multiparticulate formulations for oral delivery.

Canada’s patent landscape shows that CA2898514 occupies a specific niche, with limited direct competition but overlapping interests in multiparticulate controlled-release systems.
Patent Validity and Enforceability
- Examination history: The patents’ examinations cited prior art references but distinguished itself based on formulation specifics and manufacturing process.
- Remaining term: The patent was granted with a term expiring in 2037, providing market exclusivity for approximately 14 years from grant.
- Litigation: No significant litigation or oppositions have been filed to date.
Strategic Implications
- Patent strength: The specificity of claims offers a solid barrier against design-around strategies.
- Potential challenges: The claims may face validity challenges based on prior multiparticulate formulations, especially if similar compositions are found in prior art.
- Market exclusivity: The patent supports a narrow but defensible protection around a specific controlled-release multiparticulate formulation targeting neurological conditions.
Key Takeaways
- The patent covers a multiparticulate controlled-release formulation with specific composition and manufacturing methods.
- Its claims are narrow, focusing on the combination of active ingredient and excipient, coated with a particular polymer.
- The Canadian landscape exhibits limited direct competition but shares overlapping interests with patents filed internationally.
- Validity appears robust but should be monitored in light of prior art in multiparticulate systems.
- The patent provides a competitive advantage for its holder in targeted indications, notably in neurological and inflammatory diseases.
FAQs
1. How broad are the claims in CA2898514?
The claims are narrow, primarily covering a specific multiparticulate formulation with defined ingredients and coating methods.
2. What is the potential for patent infringement?
Any company producing a similarly controlled-release multiparticulate system with the claimed features may infringe if they do not design around the claims.
3. How does the patent compare to US or European patents?
It shares thematic similarities but emphasizes specific formulation aspects unique to the Canadian patent, which may not be explicitly claimed in foreign patents.
4. What are the main risks for patent validity?
Risks include prior multiparticulate formulations that predate the patent, which could challenge novelty or inventive step.
5. When does the patent expire, and what is the landscape outlook?
Expiration is projected for 2037; ongoing development of multiparticulate systems in Canada and abroad may impact enforceability.
