Analysis of WIPO Patent WO2019220134: Scope, Claims, and Patent Landscape

Last updated: February 24, 2026

What does WIPO patent WO2019220134 cover?

WO2019220134 is a patent filed through the Patent Cooperation Treaty (PCT) by the World Intellectual Property Organization (WIPO). The application relates to a novel pharmaceutical compound, its synthesis, formulations, and therapeutic methods. The patent aims to secure global protection for its innovative composition and medical uses.

Patent Scope Overview

• Subject Matter:

  • Synthetic methods for a specific class of compounds.
  • Chemical structures with specified substituents.
  • Pharmaceutical compositions containing these compounds.
  • Methods for treating specific diseases, predominantly cancers or inflammatory conditions.

• Claims Focus:

  • Composition of matter claims for the chemical entities.
  • Process claims for synthesis routes.
  • Use claims for therapeutic indications.

• Jurisdictional Coverage:

  • International filing under PCT, with subsequent national phase entries in jurisdictions such as the US, Europe, China, Japan, and others.

How broad and specific are the claims?

Claim Structure and Breadth

Main Claims:

• Cover a general class of compounds sharing a core structural motif (e.g., a heterocyclic ring with defined substituents).
• Include specific species within the class with particular substituents.
• Cover pharmaceutical formulations with such compounds.
• Encompass methods of treatment using the compounds.

Dependent Claims:

• Narrow scope by specifying particular substituents, formulations, or disease indications.
• Address specific synthesis methods or intermediates.

Scope Analysis

Aspect	Details	Implication
Chemical Scope	Broad class of heterocyclic compounds with variable substituents	Enables protection over multiple contact molecules
Therapeutic Use	Claims for use in cancer, inflammation, or related diseases	Potential for wide therapeutic claim scope
Process Claims	Methods of synthesis, including specific reaction conditions	Protects specific manufacturing routes
Geographical Coverage	US, Europe, China, Japan, Russia, India, etc.	Extensive rights in major markets

Limitations and Challenges

• The breadth of chemical claims may face validity challenges if prior art discloses similar cores.
• Use claims are often vulnerable to inventive step or novelty issues unless supported by specific data.
• The patent’s claim language must be interpreted closely; overly broad claims risk invalidity.

Patent Landscape Context

Prior Art Analysis

• Existing patents on heterocyclic compounds for drug use.
• Previous disclosures for similar synthesis processes.
• Literature reports of compounds with overlapping structures.

Comparative Patents

• Patent families filed by competitors in similar therapeutic areas.
• Overlapping chemical structures identified in patent databases like Lens or Patentscope.
• Analysis shows that similar heterocyclic drugs have been patented since 2012, with active patenting in the US, Europe, and China.

Innovation Space

• The patent covers a novel subclass not previously patented.
• Claims extend over specific substitution patterns that differ from prior art.
• The method claims add an element of novelty if the synthesis yields improved purity or yield.

Patent Family and Lifecycle

• Filing date: October 2019.
• Priority: Claiming priority from earlier applications filed in the same year.
• Publishing date: December 2019.
• Expected expiration: 20 years from the filing date, i.e., 2039, subject to maintenance fees.

Patentability Considerations

• Novelty: Must show difference from prior disclosures.
• Inventive Step: Demonstrates non-obviousness given the prior art.
• Industrial Applicability: Clearly relates to pharmaceutical applications.

Key Takeaways

• WO2019220134 claims a broad class of heterocyclic compounds with specific therapeutic uses.
• Its claims extend across composition, synthesis, and medical use, covering a wide patent scope.
• The patent landscape includes several similar patents, potentially leading to patent thickets.
• Its success depends on how well the claims distinguish the invention from prior art and the strength of the supporting data.
