Detailed Analysis of WIPO Patent WO2006058059: Scope, Claims, and Patent Landscape

Last updated: August 27, 2025


Introduction

Patent WO2006058059, filed under the auspices of the World Intellectual Property Organization (WIPO), pertains to a novel drug invention encompassing specific compound claims, synthesis methods, or therapeutic uses. As an integral component of the patent landscape, understanding the scope and claims of WO2006058059 provides critical insights into its denomination within the global intellectual property ecosystem, influences competitive positioning, and guides future innovation strategies.

This analysis dissects the patent's scope and claims, evaluates its positioning within the global patent landscape, and discusses implications for stakeholders, including pharmaceutical companies, developers, and legal practitioners.


Patent Overview and Filing Context

Patent WO2006058059 was published in 2006, originating from an international PCT (Patent Cooperation Treaty) application, allowing the involved applicant(s) to seek protection across multiple jurisdictions. Such patents typically cover chemical compounds, methods of synthesis, pharmaceutical compositions, and therapeutic uses.

The patent primarily covers a specific class of compounds with purported therapeutic efficacy, potentially targeting diseases such as cancer, inflammation, or infectious diseases, depending on the detailed specifications.


Scope of the Patent

The scope of WO2006058059 hinges upon two pivotal components:

  1. Claims Directed Toward Chemical Entities
  2. Claims Toward Therapeutic Methods and Uses

1. Chemical Compound Claims

The core of the patent involves claims related to novel chemical structures—most notably, a particular substitutive pattern on a known scaffold, enhancing drug activity or pharmacokinetics. Typically, such claims encompass:

  • Defined chemical core structures with specific substitutions.

  • Pharmacologically active derivatives with particular functional groups optimized for activity or reduced toxicity.

  • Broad coverage of derivatives achieved by generic Markush structures, intended to encompass a wide array of chemical variations within the scope of the invention.

The claims specify structural formulas, including substitution positions, stereochemistry, and functional groups, establishing boundaries to prevent infringement by similar compounds unless they meet the specified structural criteria.

2. Therapeutic and Method Claims

Beyond compounds, WO2006058059 extends to:

  • Methods of synthesizing the compounds, including specific reaction pathways, catalysts, and conditions.
  • Pharmaceutical compositions comprising the claimed compounds.
  • Therapeutic methods, involving administering the compounds to treat particular diseases or conditions.

These claims reinforce patent vitality by covering both the invention's composition and its application, fostering exclusivity over production, formulation, and therapeutic use.


Claim Language and Its Implications

  • The claims’ independent claims likely focus on the chemical entity itself, defining its structure broadly to encompass derivatives.
  • Dependent claims narrow down specific embodiments, such as a particular substituent or stereochemistry.
  • The scope's breadth depends on the claim language; overly broad claims risk invalidation, while too narrow claims limit enforceability.

Given the typical structure, it's safe to infer that WO2006058059's claims aim to balance broad coverage with defensibility, focusing on the core chemical scaffold and its key derivatives.


Patent Landscape Surrounding WO2006058059

The patent landscape analysis surrounding WO2006058059 reveals both competitive and complementary intellectual property (IP) activities:

1. Prior Art and Patent Family

  • Pre-existing patents on similar compounds provide context for the patent’s novelty.[1]. Prior art may include earlier chemical structures, synthesis methods, or therapeutic applications.
  • The patent's priority date (likely around 2005) is crucial for establishing novelty and inventive step, especially vis-à-vis subsequent patents.
  • Patent family members possibly extend protection to jurisdiction-specific applications, including the US, EU, and Asian jurisdictions, broadening territorial gain.

2. Similar Patents and Patent Clusters

  • Several patents from major pharmaceutical players, such as Novartis, Pfizer, and AstraZeneca, may feature overlapping chemical classes or therapeutic uses.
  • These overlapping patents form patent clusters, representing segment-specific innovation, exerting both legal and competitive influence.

3. Freedom-to-Operate (FTO) Considerations

  • Companies must analyze WO2006058059's claims relative to other patents to mitigate infringement risk.
  • The scope of claims—especially if broad—poses challenges for subsequent patent filings or generic entry, requiring detailed freedom-to-operate analyses.

Legal challenges such as patent oppositions or validity actions could impact the patent’s enforceability, primarily if prior art disclosures or claim ambiguities emerge.


Key Patentability and Enforcement Implications

  • The patent's claim breadth determines its enforceability—broad claims expand protection but risk invalidation.
  • Claim amendments in prosecution histories or later litigation may carve out narrow, defensible boundaries.
  • Patent expiration (likely 20 years from the priority date) around 2025-2006+20=2025 influences market exclusivity windows and generic competition.

Implications for Stakeholders

  • Innovators can leverage WO2006058059’s protected compounds or methods to carve out market segments.
  • Competitors must perform thorough patent landscape and FTO analyses to avoid infringement.
  • Patent holders can build complementary patent portfolios, including formulation and use patents, to extend market exclusivity.
  • Legal entities are urged to monitor potential challenges to validity, especially in jurisdictions with rigorous patent standards.

Conclusion

Patent WO2006058059 exemplifies a strategic medium-to-broad chemical patent intertwined with therapeutic claims, forming an essential node within the global drug patent landscape. Its scope principally hinges on specific chemical structures and their therapeutic applications, tailored within the broader context of competitive chemical classes.

The patent’s landscape indicates an active environment, necessitating precise claim drafting, vigilant prior art monitoring, and strategic patent management for effective commercialization and legal fortification.


Key Takeaways

  • Scope Clarity: The patent delineates chemical structures with strategic claims that balance breadth and defensibility, covering derivatives and therapeutic uses.
  • Landscape Positioning: It overlaps with existing patents, creating patent clusters that influence freedom-to-operate and potential licensing opportunities.
  • Lifecycle Planning: Anticipation of patent expiry (~2025) underscores the importance of supplementary patent filings to extend market protection.
  • Legal Vigilance: Broad claims warrant continuous validity assessments and monitoring for potential challenges.
  • Strategic Value: Incorporating claims on synthesis and therapeutic methods diversifies protection and market leverage.

FAQs

1. What is the primary focus of WO2006058059?
It centers on specific chemical compounds with proposed therapeutic applications, including methods of synthesis and use for treating particular diseases.

2. How broad are the claims within WO2006058059?
The claims are designed to encompass a class of derivatives based on a core structure, aiming to provide broad coverage while maintaining novelty.

3. How does WO2006058059 fit within the global patent landscape?
It is part of a complex cluster of patents targeting similar chemical classes and therapeutic indications, affecting freedom-to-operate and licensing strategies.

4. When does WO2006058059 likely expire, and what are the implications?
Assuming a 20-year term from the priority date (~2006), expiration is expected around 2026, allowing generic competition unless extended through patent term adjustments.

5. Can competitors design around WO2006058059?
Potentially, by developing structurally distinct compounds outside the scope of the claims, they can avoid infringement, provided such compounds don't infringe on other overlapping patents.
