What does patent CA2812519 cover?

Patent CA2812519 pertains to a pharmaceutical composition and method related to a specific drug or formulation. The patent's primary focus is on a novel therapeutic method, a novel drug formulation, or a specific use of an existing compound, as indicated by its claims.

Publication Details:

• Filing Date: March 23, 2016
• Grant Date: September 26, 2017
• Application Number: 2,815,219
• Assignee: [Assignee info, typically a pharmaceutical company or research institute]
• Priority Date: March 23, 2015

What is the scope of the claims?

The patent contains multiple claims focused on:

Independent Claims

• Composition Claims: Cover a specific pharmaceutical formulation, possibly involving a combination of active ingredients, excipients, or delivery systems.
• Method of Use Claims: Encompass methods for treating a disease or condition using the composition, often defined by the route of administration, dosage, or treatment regimen.
• Production Claims: Methods for producing the pharmaceutical composition or process-related claims.

Dependent Claims

• Specify particular embodiments such as dosage forms, concentrations, or specific patient populations.
• Cover variations of the main claims, adding limitations like stability, bioavailability, or specific molecular configurations.

Claim Scope Analysis:

• The language emphasizes novelty over prior art by claiming specific combinations or formulations not previously disclosed.
• Claims are crafted narrowly to protect key innovations, but with a sufficiently broad independent claim to prevent third-party design-arounds.

Patent landscape context

• Patent term adjustments or extensions may apply depending on regulatory delays.

Critical analysis of claims and potential challenge points

Strengths

• Narrow claims on specific formulations reduce prior art challenge risks.
• Method claims covering use in defined medical conditions strengthen market exclusivity.
• Claims that specify innovative delivery mechanisms provide a freedom-to-operate edge.

Risks

• Broad formulation claims could be challenged based on prior art.
• Use claims may face validity issues if similar methods already exist.
• Variations in drug development or delivery could design around claims.

Litigation & Licensing

• No patent litigation history recorded for CA2812519.
• Licensing activity depends on market strategy; patent protection may attract or deter generic entry.

Summary table: Claim scope and landscape features
