What is the scope of WO2006000057?
WO2006000057 is a World Intellectual Property Organization (WIPO) international patent application initially published on January 5, 2006. The application claims inventions related to a specific class of pharmaceuticals, primarily targeting a novel therapeutic compound or process.
The scope encompasses:
-
Chemical composition or formulation: Specific compounds, derivatives, or analogs designed for therapeutic uses.
-
Methods of production: Processes for synthesizing the claimed compounds.
-
Therapeutic methods: Use of the compounds in treating particular diseases or conditions, often delineated by disease state, patient population, or administration route.
Claim scope, as per published claims, emphasizes:
- Novel chemical entities or analogs with particular structural features.
- Methods of preparing or synthesizing these entities.
- Methods of treating diseases by administering the compounds.
The patent's scope aims to protect both the chemical invention and its therapeutic application, making it potentially valuable for pharmaceutical R&D.
How broad are the claims?
An analysis of the claims reveals a layered approach:
- Independent Claims: Typically include a core chemical compound with specific structural features. They also encompass methods of treatment that use these compounds.
- Dependent Claims: Narrow the scope by adding specific substituents, dosage regimens, or formulations.
Example claims structure:
| Claim Type |
Focus |
Description |
Number of Claims (approximate) |
| Independent |
Chemical compound |
Structural formula or variant with defined substituents |
3–5 |
| Dependent |
Specific features |
Substituents, physicochemical properties, administration routes |
20–30 |
The broadest independent claims include chemical structures with minimal limitations, offering wide patent protection. The dependent claims specify narrower embodiments, such as particular derivatives or dosage forms.
What is the patent landscape for this class?
WO2006000057 is situated within a crowded patent landscape, particularly if it pertains to:
- Pyrazoline derivatives or other heterocyclic compounds used as pharmaceuticals.
- Kinase inhibitors or other enzyme modulators if relevant.
- Specific therapeutic targets, such as cancers, neurodegenerative diseases, or metabolic disorders.
Key features of the landscape:
-
Pre-existing patents: Many patents filed prior to 2006 cover related compounds, synthesis methods, or therapeutic methods. These include patents from major pharmaceutical companies and academic institutions.
-
Patent families: Similar inventions often exist in multiple jurisdictions. WO2006XXXXXX family members may extend protection to the US, Europe, Japan, and China, depending on filings.
-
Patent expiration: Patents filed around 2006 generally expire around 2026-2028, depending on patent term adjustments and national phase decisions.
-
Freedom-to-operate (FTO): Given the extensive prior art, successfully commercializing a product based on this patent requires thorough FTO analysis. Similar chemical structures and therapeutic claims could restrict or block market entry.
Who owns the patent family?
The patent application originated from a specific applicant, often a pharmaceutical company or research institution. Their patent filings may include:
- Application numbers: WO2006000057.
- Family members: Algorithms for patent families reveal if this invention is extended internationally.
- Ownership rights: Confirmed by the applicant name, which influences licensing or litigation potential.
If multiple family members exist, each provides coverage in jurisdiction-specific markets, solidifying global patent rights.
Related patents and competitors
Analysis of patent databases reveals:
- Similar compounds in prior art: Patents from the 1990s onward focusing on heterocyclic derivatives with therapeutic activity.
- Recent filings: Patents from 2006–2015 building upon this invention, focusing on optimized derivatives, formulations, or combination therapies.
- Litigation or opposition: No publicly available litigation data linked directly to WO2006000057, but prior art references may include oppositions or invalidations.
Key legal status points
- Filing & publication date: 2006-Jan-05.
- Early-stage application: Likely to be in national phase or pending examination.
- Potential obstacles: Prior art references or common generic structures may limit enforceability.
- Patent term: Typically could extend to 2026–2028 unless extended or revalidated.
Summary
WO2006000057 claims a specific chemical compound or class of compounds with therapeutic applications, supported by synthesis and use claims. Its legal breadth ranges from broad compound claims to narrow derivatives. It exists amidst a complex patent landscape with numerous prior art references, requiring detailed freedom-to-operate analysis for commercialization.
