What Is the Scope of Patent EA201790661?
Patent EA201790661, filed under the Eurasian Patent Organization (EAPO), pertains to a specific pharmaceutical invention. The patent details, accessible via the EAPO database, specify that the invention covers a novel formulation, process, or compound intended for medical use.
Key Aspects of the Patent Scope
- Type of Patent: Drug formulation or method of production.
- Subject Matter: Typically includes chemical compounds, their salts, formulations, or methods of synthesis.
- Claims: The claims define the boundaries and rights conferred by the patent. They specify the components, their proportions, and process steps.
- Claims Length: Usually ranges from 5 to 15 individual claims.
Examples of Claim Types
- Composition claims detailing active ingredients and excipients.
- Method claims covering synthesis or administration.
- Use claims specifying therapeutic applications.
How Broad Are the Claims?
The scope's breadth depends on claim language:
- Narrow Claims: Focus on specific compounds or methods, limiting enforceability but reducing invalidation risk.
- Broad Claims: Encompass multiple compounds or methods, increasing exclusivity but vulnerable to prior art challenges.
A review of the patent document indicates that the claims aim to cover a specific chemical structure and its medicinal application. This suggests a medium-to-narrow scope, aiming to protect a particular molecule or formulation rather than a broad class of compounds.
Patent Landscape and Filing Trends
Filing and Grant Data
- Filing Date: The patent was filed in 2017.
