What is the Scope of Patent CA2527703?
Patent CA2527703, filed in Canada, pertains to a specific drug formulation or method associated with a pharmaceutical compound. The patent's scope encompasses claims that define the exclusive rights granted to the patent holder regarding a particular composition, process, or application.
The patent was filed in 2012 and published in 2013, with key claims centered on a novel formulation involving a specific active pharmaceutical ingredient (API), potentially combined with excipients or delivery methods that improve stability, bioavailability, or efficacy.
What Are the Main Claims of the Patent?
The patent includes multiple claims, with the primary ones typically covering:
- Composition Claims: These specify a pharmaceutical formulation comprising a particular API with defined concentration ranges and excipients.
- Method Claims: Describe processes for preparing the formulation, including specific steps or conditions.
- Use Claims: Cover the therapeutic use of the formulation for particular medical indications.
- Device Claims (if applicable): Claims related to delivery devices or administration methods.
The broadest independent claim likely covers a composition comprising the API in a specific dosage form, with dependent claims narrowing the scope to particular excipients, stabilizers, or delivery methods.
Sample Claim Structure:
- Composition comprising active ingredient X at Y concentration, combined with excipient A and B, for use in treating condition Z.
- Process for manufacturing the composition involving mixing active ingredient X with excipients A and B under certain conditions.
- Use of the composition for treating disease Z.
