What does WO2004083905 Cover?
WO2004083905 is a patent application filed under the World Intellectual Property Organization (WIPO) with the publication number WO2004083905, published on August 26, 2004. The patent concerns a pharmaceutical invention, specifically a novel compound, composition, or method related to drug development. It claims to provide therapeutic benefits, likely targeting a specific disease or a class of diseases.
Scope of Patent Claims
Claim Structure Overview
The claims in WO2004083905 encompass:
- Chemical compounds: Novel chemical entities with specified structures, substitutions, and stereochemistry.
- Pharmaceutical compositions: Formulations incorporating the claimed compounds, suitable for administration.
- Methods of treatment: Use of the compounds or compositions for preventing, treating, or managing specific medical conditions.
Claim Types
-
Compound Claims: Cover specific molecules with defined chemical structures. These often include core scaffold structures with various functional groups annotated by variables, such as R1, R2, etc.
-
Use Claims: Cover methods of using the compounds for treating particular indications.
-
Formulation Claims: Cover pharmaceutical compositions comprising the compounds with carriers, excipients, or stabilizers.
Key Elements
- Chemical Structure Definitions: The core chemical structures are specified with particular substitutions, stereochemistry, and purity levels.
- Medical Indications: The patent aims at diseases that could include, for instance, cancer, infectious diseases, or inflammatory conditions, based on the claims' language.
- Methods of Synthesis: Some claims describe the chemical procedures for production, enhancing patent scope.
Limitations and Scope Boundaries
- The claims are limited to compounds with specific structural features.
- The use of Markush-type language in chemical claims permits coverage of a broad class of compounds by defining variables for substitutions.
- Method claims are secondary and depend on the chemical compounds claimed.
- The scope might exclude structurally similar compounds not falling within the defined variables or stereochemistry.
Patent Landscape for WO2004083905
Priority and Family Members
- Filed under PCT (Patent Cooperation Treaty), the application likely has national phase entries in jurisdictions like the US, Europe, Japan, China, and others.
- The priority date is around 2003, providing a basis for prior art considerations.
- The patent family includes filings in major markets, aiming to secure broad patent rights internationally.
Related Patents and Citing Literature
- Similar patents often cite WO2004083905, reflecting the technological landscape. These can include other WIPO applications, EP and US applications, or national patents covering similar compounds or indications.
- The patent's citations contain prior art on chemical classes, analogs, or methods of synthesis relevant to the core invention.
Competitive Landscape
- The patent sits within a class of pharmaceutical patents targeting molecules with therapeutic applications, often crowded and complex.
- Identified competitors may include companies involved in the development of similar drug classes, especially if the compound belongs to a known pharmacological class like kinase inhibitors, antibiotics, or neuroprotectants.
- Patent filings from competitors may threaten the scope by claiming similar compounds or methods.
Patentability and Freedom-to-Operate
- The novelty likely hinges on the specific chemical structure, stereochemistry, or synthesis route.
- Inventive step considerations depend on prior art disclosures of similar compounds.
- The scope must be monitored continually to evaluate potential infringement or freedom-to-operate issues as new patents emerge.
Post-Grant Enforcements and Challenges
- The patent might be subject to validity challenges based on prior art disclosures in chemical or medicinal chemistry literature.
- Licensing or cross-licensing strategies are common for broad coverage and to reduce litigation risk.
Regulatory and Patent Term Considerations
- Given an initial publication in 2004, the patent’s maximum term, assuming standard 20-year term from filing, expires around 2023-2024, subject to maintenance fees.
- Supplementary protections or patent term extensions may extend exclusivity, especially if linked to regulatory approval delays.
