What Does Patent EA201892568 Cover?
Patent EA201892568 was granted by the Eurasian Patent Organization (EAPO). It applies to a pharmaceutical invention, with a priority date established on a specific date. The patent protection extends across member states of the EAPO, which includes Russia, Armenia, Belarus, Kazakhstan, and Kyrgyzstan. The patent expiration date is typically 20 years from the filing date, subject to maintenance fees and legal status.
The patent claims cover a particular compound, formulation, or method of use. The precise language of these claims defines the scope of protection, including:
- The chemical structure or composition
- Method of preparation
- Therapeutic application
Patent rights do not typically extend beyond these claims; therefore, the scope is as broad or narrow as the claims allow.
What Are the Specific Claims?
The claims in EA201892568 detail the novel aspects of the invention. They generally include:
- A chemical compound with defined structural features
- A pharmaceutical formulation comprising the compound
- A unique method of synthesizing the compound
- Specific use cases, such as treating a certain disease
For example, Claims 1-3 might specify the chemical structure and broad formulation, while Claims 4-6 focus on particular dosage forms or methods of administration. Third-party infringing activity hinges on these claims.
The claims are written with legal precision, balancing broad coverage and specificity. Broad claims aim to prevent competitors from making similar compounds, while narrower claims protect specific embodiments.
