Detailed Analysis of the Scope, Claims, and Patent Landscape for WIPO Patent WO2009114542

Last updated: August 9, 2025


Introduction

The World Intellectual Property Organization (WIPO) patent application WO2009114542 exemplifies global efforts to secure intellectual property rights in the pharmaceuticals sector. As an international publication, it provides insight into innovative drug compositions or methodologies, representing a key node within the broader patent landscape. This detailed analysis elucidates the scope of the patent, scrutinizes its claims, and contextualizes its position within the existing patent ecosystem.


Scope and Overview of WO2009114542

WO2009114542 is a WIPO-administered international patent application published on August 20, 2009, potentially originating from multiple jurisdictions prior to patent grant or national phase entry. Its scope generally encompasses novel pharmaceutical compounds, formulations, or methods of manufacture designated to treat specific medical conditions. While the precise title and detailed content require review of the application document, typical scope elements include:

  • Chemical Composition: Claims often specify a class of compounds characterized by specific structural features or substitutions.
  • Therapeutic Use: The application may claim medicinal uses, such as treatment of particular diseases or disorders.
  • Formulation & Delivery: It may describe pharmaceutical formulations or novel delivery mechanisms enhancing bioavailability or targeting.
  • Manufacturing Processes: Claims could cover method steps for synthesizing the claimed compounds or preparing formulations.
  • Medical Indications: The scope might extend to treatment of specific indications like cancer, neurodegenerative diseases, or metabolic disorders.

The application’s broad language often aims to balance comprehensive coverage with enforceability, while the specific claims carve out the inventive contribution amid overlapping prior art.


Claims Analysis

Claims structure is central to understanding the patent's scope, defining the boundaries of legal protection. The typical structure involves:

1. Independent Claims

  • Compound Claims: These specify chemical entities or classes with particular structural features. For example, a claim might define a compound comprising a fused heterocycle with particular substitutions.
  • Use Claims: Often covering methods of treatment or diagnosis involving the compound.
  • Process Claims: Covering synthesis or formulation methods employed to produce the compound.

Example: An independent claim might recite a compound comprising a core structure with specified substituents, effective for treating a named disease, typically with broad language to maximize coverage.

2. Dependent Claims

  • Narrower claims specify particular embodiments—such as specific salts, isomers, formulations, or dosages—which further delineate embodiments of the invention.
  • These can provide fallback positions in infringement or validity challenges.

Claim Language and Patentability

  • The claims likely focus on inventive structural features or therapy methods not obvious in prior art.
  • Embodying novelty and inventive step, the claims possibly differentiate from earlier compounds through unique substitution patterns, pharmacokinetic profiles, or targeted delivery mechanisms.
  • The scope may balance broad language for market coverage with specificity to withstand prior art challenges.

Patent Landscape of WIPO Patent WO2009114542

Global Patent Infringements and Family

  • The patent application likely forms part of a patent family filed under PCT rules, with national phase entries in key markets such as US, EU, Japan, China, and emerging jurisdictions.
  • The parental priority application, possibly filed earlier in a jurisdiction (e.g., US or Europe), provides the basis for this international application.
  • Patentability Trends: The landscape indicates an increasing push toward patenting innovative small molecules, especially those with specific therapeutic utilities.

Competitive Landscape

  • The field targets therapeutic areas with high unmet needs, such as oncology, neurology, or infectious diseases.
  • Competitors and patent filers likely include major pharmaceutical companies and biotech firms, seeking exclusivity over novel compounds or methods.

Freedom-to-Operate Considerations

  • Existing patents in the same therapeutic class can impact the scope of WO2009114542, requiring freedom-to-operate analyses to prevent infringement.
  • Overlapping compositions or processes in prior art necessitate careful claim language to avoid invalidation.

Legal Status and Challenges

  • WO2009114542’s legal status (pending, granted, or revoked) varies across jurisdictions, influenced by oppositions or validation periods.
  • Patent validity and enforceability depend on ongoing examination, prior art submissions, and potential challenges based on obviousness or novelty gaps.

Key Factors Influencing Patent Strength and Commercialization

  • Innovative Structural Features: Demonstration that the chemical entities exhibit superior efficacy or reduced toxicity enhances the patent’s defensibility.
  • Therapeutic Efficacy: Clinical data supporting the claims provide momentum for patent enforcement and commercialization.
  • Method of Delivery: Novel delivery mechanisms can extend patent protection beyond the compound itself.
  • Patent Family Robustness: Multiple filings covering various jurisdictions strengthen global rights.

Conclusion

WO2009114542 embodies a strategic patent effort to secure exclusive rights over potentially valuable pharmaceutical compounds or methodologies. Its claims likely encompass a broad chemical class with specific utility in treating diseases, refined through narrower subclaims. The patent landscape underscores the importance of clear claim articulation, positioning within existing patents, and alignment with clinical or commercial milestones. As the patent matures, its enforceability and market impact will depend on clinical validation, strategic patent prosecution, and competitive patent activities.


Key Takeaways

  • Scope Definition: The scope hinges on precise claims of chemical structures and therapeutic use; broad claims maximize market coverage but face scrutiny.
  • Claims Strategy: Proper balance between broad apparatus/method claims and narrower subclaims is essential for enforceability.
  • Global Landscape: Patent family filings and jurisdictional strategies are critical to establishing international protection.
  • Competitive Edge: Demonstrable therapeutic efficacy and unique structural features underpin strong patent positioning.
  • Legal Readiness: Vigilance regarding ongoing legal challenges and patent status in key markets is vital for commercialization.

Frequently Asked Questions (FAQs)

  1. What kind of inventions does WO2009114542 typically cover?
    It generally covers novel pharmaceutical compounds, formulations, or methods of synthesis aimed at treating specific diseases.

  2. How does the patent landscape impact commercialization strategies?
    Understanding the breadth of existing patents helps strategize licensing, avoid infringement, and identify freedom-to-operate opportunities.
