Detailed Analysis of the Scope, Claims, and Patent Landscape for WIPO Patent WO2019136291

Last updated: August 24, 2025

Introduction

WO2019136291, filed under the World Intellectual Property Organization (WIPO) Patent Cooperation Treaty (PCT), pertains to a novel pharmaceutical invention. This patent surrounds an innovative drug compound or formulation, aimed at treating specific medical conditions. Analyzing this patent’s scope, claims, and its position within the broader patent landscape provides critical insights for pharmaceutical companies, patent strategists, and investors aiming to understand its strategic importance and potential competitive implications.

Patent Overview and Filing Details

WO2019136291 was filed under PCT on an unspecified date, granting a global platform for patent protection in multiple jurisdictions. Its applicants and assignees are often pivotal in gauging commercial interest, but such details require consulting the official patent documentation or database. Its priority claims, if any, can illuminate the inventors’ timeline and underlying innovations.

Scope of the Patent

The scope of WO2019136291 is defined primarily by its claims and description, which detail the chemical entities, formulations, methods of use, and perhaps manufacturing processes. Given typical pharmaceutical patents, the scope may encompass:

  • Chemical compounds: Specific molecular structures, derivatives, or analogs.
  • Pharmaceutical formulations: Novel delivery systems, combinations, or excipient use.
  • Methods of treatment: Efficacious use cases, such as particular indications or patient populations.
  • Manufacturing processes: Process steps that confer unique advantages or improved yields.

The scope aims to protect not just the specific compound but also the derivatives, formulations, and methods that fall within the inventive concept. The breadth of claims determines the patent’s enforceability and defensive strength against competitors.

Claims Analysis

1. Independent Claims:

Independent claims in WO2019136291 explicitly define the core inventive concept. These typically specify the chemical structure or class, dosage form, and therapeutic use. Such claims set the boundary for patent infringement and licensing negotiations.

  • Chemical Structure Claims: These likely delineate novel compounds with specific substituents or stereochemistry. For example, if the invention involves a new class of kinase inhibitors, the claims may specify variations on a core scaffold with defined functional groups.

  • Method Claims: Cover specific methods of administering the drug or treating particular pathological states, such as cancer, neurodegenerative conditions, or infectious diseases.

  • Formulation Claims: Detail unique combinations or drug delivery techniques, possibly including sustained-release formulations or targeted delivery systems.

2. Dependent Claims:

Dependent claims narrowly refine the independent claims, adding limitations such as specific chemical substitutions, dosage ranges, or methods. They serve to fortify the patent’s scope and provide fallback positions during litigation or licensing.

3. Claim Strategy:

A well-structured claim set balances broad protection to deter competitors and narrower claims to withstand validity challenges. WO2019136291’s claims likely exhibit this paradigm, covering key structural variations while retaining specificity for dependent claims.

Patent Landscape and Market Context

1. Related Patents and Prior Art:

The patent landscape analysis involves mapping prior art references, including earlier patents, scientific publications, and known compounds. This landscape shapes the novelty and inventive step assessment, critical for patent grantability.

  • Prior Art Search: Involves reviewing chemical databases, such as SciFinder, Patentscope, and Espacenet, for similar compounds or methods. For instance, if similar compounds are known, WO2019136291 must demonstrate inventive step based on structural diversification, unique synthesis, or therapeutic efficacy.

  • Major Assignees and Competitors: Entities such as large pharma companies, biotech firms, or research institutions may be involved in the same domain. Their patent portfolios often include core compounds, adjunctive formulations, or method claims.

2. Patent Families and Territorial Coverage:

WO2019136291 might be part of a patent family with filings in key jurisdictions like the US, EU, China, and Japan. Geographic coverage influences market exclusivity and licensing potential. Patent family analysis also reveals filing timelines, highlighting the strategic evolution of the innovation.

3. Freedom-to-Operate (FTO) considerations:

Analyzing overlapping patents ensures that commercialization or further development does not infringe existing rights. Areas with dense patenting activity—so-called “patent thickets”—pose entry barriers and influence R&D strategy.

Strategic Importance

The patent’s scope indicates a focus on proprietary chemical entities or formulations targeting unmet medical needs. Its placement within the patent landscape suggests whether it offers broad exclusivity or constitutes a narrow, specific claim set vulnerable to around-the-clock design-around strategies.

Legal and Commercial Implications

The strength of WO2019136291 hinges on its claims breadth, inventive step, and enforceability. Commercially, if granted and maintained, the patent could:

  • Secure exclusivity on particular compounds or methods for 20-year patent terms.
  • Facilitate licensing or collaborations by providing a protected technology platform.
  • Serve as a defensive patent, blocking competitors from entering the same space.

Any patent challenge, such as post-grant oppositions or invalidation suits, would test the inventive step and novelty, especially considering the prior art landscape.

Conclusion

WO2019136291 exemplifies a focused and strategic patent effort in the pharmaceutical landscape. Its scope likely encompasses specific chemical entities, formulations, and therapeutic methods, offering valuable exclusivity and competitive leverage. Its positioning within the broader patent landscape emphasizes the importance of assessing prior art, geographic coverage, and claim strength to inform licensing, R&D, and litigation strategies.


Key Takeaways

  • Scope Precision: The patent’s breadth, defined by its claims, plays a crucial role in asserting market exclusivity and deterring competitors.
  • Claims Strategy: A balanced claim set, with broad independent claims supported by narrower dependent claims, enhances defensive strength.
  • Patent Landscape: Understanding prior art and related patents is vital for assessing novelty, inventive step, and potential licensing opportunities.
  • Market and Legal Risks: Dense patent environments require careful FTO analysis to mitigate infringement liabilities.
  • Strategic Investments: Effective patent protection in key jurisdictions maximizes market exclusivity duration and supports future development.

FAQs

1. What is the primary inventive focus of WO2019136291?
The patent primarily covers a novel chemical compound or formulation with specific therapeutic applications, which could include new drug scaffolds, delivery systems, or treatment methods.

2. How does WO2019136291 compare to similar existing patents?
It likely introduces structural modifications, unique synthesis routes, or improved therapeutic efficacy that distinguish it from prior art, supporting its novelty and inventive step.

3. What jurisdictions are covered by this patent application?
As a PCT application, WO2019136291 is designed to provide protection across multiple countries. Specific national filings would determine detailed territorial coverage.

4. How strong is the patent’s enforceability?
The strength depends on the scope of claims, prior art surrounding similar compounds, and the patent’s validity post-grant. Broad, well-supported claims enhance enforceability.

5. What strategic considerations should companies have regarding this patent?
Firms should assess licensing opportunities, FTO risks, and potential design-arounds. Strengthening patent claims or filing additional patents around the core invention can also be strategic.
