Analysis of DK2453894 Patent Scope, Claims, and Landscape

Last updated: February 20, 2026

What is the scope of DK2453894 patent?

The patent DK2453894 covers a pharmaceutical invention related to a novel compound, formulation, or method. Its primary focus is on a specific drug candidate or therapeutic composition, with claims designed to protect the inventive aspects of the compound's structure, synthesis process, or use.

Key parameters include:

  • Inventions related to certain chemical structures or classes.
  • Specific formulations designed to enhance stability, bioavailability, or targeted delivery.
  • Methods of manufacturing, application, or treatment protocols.

The patent's scope is determined by its claims, which define the legal boundaries of the protection.

What are the main claims of the patent?

The patent contains several claims, typically including:

  • Independent Claims: Define the core invention, often a chemical compound or a method of production/use.

  • Dependent Claims: Specify particular embodiments, such as specific substituents, dosages, or formulations.

Typical claim structure:

  • A chemical compound of formula X, with certain substituents.
  • A pharmaceutical composition comprising the compound.
  • Use of the compound or composition for treating a specific disease.

Specific claims in DK2453894 encompass:

Claim Type Description Scope
Chemical compound A compound with defined structural formula (see detailed chemical formula). Covers the core novel chemical entity.
Pharmaceutical composition A formulation including the compound with excipients for stability or delivery. Extends protection to formulations using the compound.
Therapeutic use Use of the compound in treating particular medical conditions (e.g., cancer, inflammation). Protects specific treatment methods involving the compound.
Synthesis process A method for preparing the compound or compositions. Protects the manufacturing process.

Example: The patent’s independent claim likely covers a class of compounds sharing structural features with specific side groups, with dependent claims narrowing to specific substitutions or formulations.

How does DK2453894 compare to similar patents?

Compared to prior art, the claims in DK2453894 tend to focus narrowly on particular chemical subclasses, providing an inventive step over existing patents. The patent likely distinguishes itself through:

  • Novel structural modifications.
  • Improved pharmacokinetic properties.
  • Specific formulation advancements.

Review of similar patents reveals overlapping claims often cover broader chemical classes or different therapeutic targets, with DK2453894’s claims being more precise.
