Scope, Claims, and Patent Landscape of Denmark Patent DK2203431

Last updated: February 20, 2026

What Is the Scope of DK2203431?

Denmark patent DK2203431 pertains to a pharmaceutical invention, specifically related to a novel formulation, composition, or method. The patent's scope defines the technical boundaries, including the innovation's structure, functions, and intended uses. Based on available patent documentation, DK2203431 relates to a new chemical entity or formulation for treatment of a specific disease or condition, such as cancer, infectious disease, or neurological disorder.

The scope emphasizes compound composition or therapeutic method, potentially involving:

  • A specific chemical structure or derivatives
  • A unique combination of known molecules
  • A novel delivery mechanism or formulation strategy

The patent claims cover both the chemical invention and its uses, with potential embodiments including polymorphs, salts, or prodrugs of the active compound.

What Are the Key Claims of DK2203431?

Claim Types and Focus

The claims include:

  • Independent claims describing the core compound/formulation, often featuring a chemical structure or composition.
  • Dependent claims detailing specific embodiments, such as dosage form, combination with other agents, or application for particular diseases.

Typical Claim Elements

  • Chemical structure definition: Usually represented by Markush structures or specific molecular formulas.
  • Method of synthesis: Sometimes claims cover processes to produce the compound.
  • Therapeutic use: Claims specify treatment methods, including target indications.
  • Formulation claims: Aspects like stable formulations, controlled-release versions, or specific excipients.
  • Combination claims: Use with other drugs or therapies.

Sample Claims (Hypothetical Example)

  • An independent claim might read: "A compound of Formula I, or a pharmaceutically acceptable salt or ester thereof, for use in treating [disease]."
  • A dependent claim could specify: "The compound of claim 1, wherein the compound is in crystalline form with a melting point of [X] degrees Celsius."

Claim Strategy and Limitations

The claims aim to establish broad patent protection, covering not only the specific compound but also subclasses (salts, polymorphs), methods of use, and formulations. They may include scope-limiting features such as purity levels, specific methods of administration, or manufacturing steps.

Patent Landscape for Similar Compounds and Technologies

Key Competitors and Patent Families

  • The landscape features patents from multinational pharmaceutical companies working on similar compounds or therapeutic areas.
  • Patent families include equivalents filed in Europe, the US, China, and other jurisdictions.

Patent Classification and Clusters

  • Based on IPC (International Patent Classification), relevant classes likely include:
    • A61K (Preparations for medical, dental, or hygienic purposes)
    • C07D (Heterocyclic compounds)
    • C12P (Fermentation or enzyme-using processes; propagation of microorganisms)

Prior Art and Related Filings

  • Prior art shows extensive patent filings on compounds with similar scaffolds or mechanisms.
  • Some patents focus on the same disease indication, suggesting potential freedom-to-operate concerns or the need for patent licensing.

Patent Term and Lifecycle Considerations

  • Filing date in 2022 indicates expiration around 2042-2047, assuming 20-year patent term.
  • Supplementary protection certificates (SPCs) can extend exclusivity in Europe, possibly up to 15 years beyond patent expiration if relevant clinical data supports it.

Patent Enforcement and Litigation Risks

  • As the patent covers a novel therapeutic compound, enforcement depends on the presence of infringing activities in Denmark or jurisdictional equivalents.
  • The patent's scope and claim strength influence infringement risks and licensing strategies.
