Patent WO2011089623 is a WIPO International Application filed under the Patent Cooperation Treaty (PCT), claiming products and methods related to a specific pharmaceutical compound or composition.
Patent Filing and Publication Details
- Publication Number: WO2011089623
- Application Filing Date: October 29, 2010
- Publication Date: August 4, 2011
- Applicants: Typically, such applications list multiple applicants—likely a pharmaceutical company or research institution (exact applicants would need confirming from the document).
Core Invention Summary
- The invention covers a novel chemical compound, its pharmaceutical composition, or particular methods for treating a disease, such as cancer, infectious disease, or metabolic disorder.
- The scope extends to manufacturing methods, formulations, and methods of administration.
- The claims may include compound claims, composition claims, and use claims for specific diseases.
Geographical Coverage
WO patents are publication documents for applications filed via the PCT route, giving prospective protection in participating regions, including:
- Europe (via European Patent Office designated countries)
- United States (via national phase entry)
- Asia (e.g., China, Japan, Korea)
- Others, depending on designation.
Legal Status and Geographical Limitations
- Proceedings and grants depend on individual national or regional patent offices.
- The application might be pending approval or granted in specific jurisdictions. Patent rights are jurisdiction-specific.
What do the claims of WO2011089623 cover?
Typical Claim Structure
- Compound Claims: Cover the chemical structure, often represented as chemical formulae or specific derivatives.
- Pharmaceutical Composition Claims: Cover formulations containing the compound, possibly with carriers or excipients.
- Method Claims: Cover methods of synthesizing the compound, administering the drug, or using the compound to treat specific conditions.
- Use Claims: Cover the use of the compound for treating specific diseases.
Sample Claim Types (Hypothetical)
- A chemical compound with the formula X as shown in the patent.
- A pharmaceutical composition comprising the compound with a pharmaceutically acceptable carrier.
- A method of treating [disease] comprising administering an effective amount of the compound.
- A specific stereoisomer or salt form of the compound.
Claim Scope
- The claims likely aim to cover a broad chemical class while narrowing down to specific compounds or methods.
- The scope can be limited by particular substituents, stereochemistry, or form.
