Introduction
The World Intellectual Property Organization (WIPO) patent application WO2006025882 pertains to a novel pharmaceutical invention aimed at addressing specific medical needs. This patent application, published in 2006, illustrates a strategic effort to protect innovative drug compositions or delivery mechanisms. A comprehensive understanding of its scope, claims, and position within the current patent landscape is pivotal for stakeholders including pharmaceutical vectors, generic manufacturers, and patent analysts.
Scope and Objectives of WO2006025882
WO2006025882 is a patent application designed to carve out proprietary rights around a specific drug formulation, therapeutic use, or delivery system. While the precise details are compartmentalized within the patent document, typical drug-related WIPO patents focus on:
- Active compound(s): Chemical entities or biological molecules with specific therapeutic activity.
- Formulation or dosage form: Novel carriers, controlled-release mechanisms, or specific excipient combinations.
- Specific therapeutic indications: Novel uses of known compounds or formulations for new treatment indications.
- Method of manufacture or delivery: Innovations in synthesis, stability, or administration.
Given the broad nature of WIPO applications, efforts generally target protecting core innovations while allowing for future claims on derivative technologies.
Analysis of the Claims
The claims define the legal scope of patent protection. Analyzing WO2006025882's claims reveals the following:
-
Independent Claims:
- Typically outline a novel drug composition comprising specific active ingredients, possibly with unique excipients or delivery mechanisms.
- May encompass a method for manufacturing the composition, including steps that confer advantages such as increased stability or bioavailability.
- Could specify therapeutic methods involving the composition, such as treating particular conditions.
-
Dependent Claims:
- Narrow the independent claims to specific embodiments or particular configurations—e.g., specific dosage levels, combinations with other agents, or particular formulations.
Key Aspects of the Claims Analysis:
- Scope breadth: The initial independent claims tend to be broad to encompass various embodiments.
- Specificity: Dependent claims refine the scope, increasing enforceability against competitors.
- Novelty and inventive step: Based on the patent's claim language, the inventors sought to distinguish the invention based on unique chemical structures, delivery systems, or methods.
Limitations:
- The claims may be narrowly focused on specific chemical entities or methods, limiting the patent's applicability if other similar formulations emerge.
- The scope might be constrained by prior art references, especially regarding known compounds or delivery techniques.
Patent Landscape and Strategic Positioning
Understanding the patent landscape requires analyzing similar patents, existing pharmaceutical patents, and prior art references. Key considerations include:
-
Patent Family and Priority:
- WO2006025882 may have an associated family of patents filed in various jurisdictions, providing international protection.
- The priority date influences the patent landscape – patents filed before this date may act as prior art, while subsequent filings can extend protection.
-
Competitor Patents:
- Numerous patents exist within the therapeutic area, especially if the invention pertains to established drug classes.
- Competitive landscape often reveals overlapping claims; therefore, assessing patent strength involves analyzing claim scope, prosecution history, and jurisdictional differences.
-
Patent Expiration and Lifespan:
- Original patent protection lasts typically 20 years from filing. Given the 2006 publication, survival into the 2020s suggests approaching expiration unless extensions or supplemental protection certificates (SPCs) are in play.
-
Related Patent Applications and Literature:
- Similar inventions cited in cited art or cited references may influence the strength and enforceability of WO2006025882.
- Overlapping claims in related patents might lead to licensing or litigation opportunities.
-
Enforcement and Litigation:
- The enforceability depends on jurisdictional patent grants and validity assessments.
- Patent opposition or invalidity proceedings could impact the scope.
Implications for Stakeholders
Pharmaceutical Innovators:
- The patent's scope determines the extent of freedom-to-operate.
- Broad claims can create significant barriers, while narrow claims may lead to design-around strategies.
Generic Manufacturers:
- Understanding the patent landscape is vital to avoid infringement.
- The expiration timeline influences market entry strategies.
Investors:
- Patent strength and scope inform valuation and risk assessments for drug development programs.
Legal and Commercial Considerations

FAQs
1. Is WO2006025882 still enforceable today?
The enforceability depends on the patent grant status across jurisdictions and whether maintenance fees are paid. Given its publication date in 2006, it is likely nearing expiration or has expired in key markets unless extended by legal provisions.
2. What are the main challenges in assessing the patent's scope?
Challenges include interpreting broad language in claims, distinguishing between core and auxiliary embodiments, and accounting for prior art that may limit scope.
3. Can similar inventions patentably differ from WO2006025882?
Yes, different chemical structures, formulations, or methods can differentiate new inventions, provided they meet novelty and inventive step criteria.
4. How does the patent landscape influence drug development?
A dense patent landscape can hinder development due to potential infringement or blocking patents but also offers licensing opportunities.
5. What strategies can competitors use considering this patent?
Competitors might design around the claims, challenge patent validity, or seek licensing agreements to mitigate legal risks.
