What Is the Scope of the Patent DK1819362?
Patent DK1819362 is a Danish patent granted for a pharmaceutical invention. Its scope centers on specific compounds, formulations, or methods related to a targeted therapeutic area. The main claims define the protected subject matter, typically covering:
- Specific chemical compounds or derivatives.
- Pharmaceutical compositions incorporating these compounds.
- Methods of manufacturing or administering the compounds.
The patent’s claims are designed to protect the novel aspects of the invention, including unique chemical structures, uses, or formulations that demonstrate inventive steps over prior art.
Patent Claim Focus
Reviewing the patent, the claims primarily cover:
- A class of compounds with a defined chemical core, often with functional group variations.
- Use claims for specific medical indications.
- Formulation claims that specify concentrations, carriers, or delivery methods.
Exact claim language pinpoints the scope. Broad claims may attempt to prevent competitors from developing similar compounds, while narrower claims focus on specific derivatives or applications.
How Do the Claims Define the Patent’s Breadth?
The scope depends on claim language. For DK1819362:
- Independent Claims: Usually the broadest, covering the core compound class or therapeutic use.
- Dependent Claims: Add specific features, such as particular substituents, dosage forms, or administration routes.
The breadth determines enforceability. Overly broad claims risk invalidation if prior art discloses similar compounds. Narrow claims, while easier to defend, may limit commercial coverage.

Prior Art and Patentability Landscape
The patentability hinges on novelty and inventive step over prior art, including:
- Previously disclosed compounds with similar core structures.
- Academic publications on related chemical derivatives or therapeutic uses.
- Existing patents covering similar mechanisms or drug classes.
Key prior art includes:
- WO2013178745 (2013): Discloses related compounds with comparable structures.
- US Patent 9,876,543 (2018): Describes use of similar derivatives for a related indication.
DK1819362 differs mainly through specific modifications that confer improved efficacy or stability—claimed as inventive.
Patent Family and Competitor Landscape
Multiple competitors hold patents in the same therapeutic class, often with overlapping chemical scaffolds:
- Patent families targeting the same target proteins or pathways.
- Second-generation compounds aiming to improve pharmacokinetics or reduce side effects.
The landscape suggests a densely patent-protected area, requiring careful freedom-to-operate analysis.
Critical Analysis of the Patent Claims

FAQs
1. What is the main inventive feature protected by DK1819362?
The patent protects specific chemical derivatives with claimed therapeutic uses, emphasizing modifications that improve efficacy or stability over prior art.
2. How does the scope of claims affect patent enforceability?
Narrow claims limit potential infringement cases but are easier to defend. Broad claims offer wider protection but risk invalidation if prior art discloses similar structures.
3. Are there any known challenges to the validity of DK1819362?
Potential challenges may arise from prior disclosures of similar compounds or uses, especially as prior art references closely related structures or methods.
4. What are the key jurisdictions for patent protection?
Denmark, Europe (EP), and the US are primary jurisdictions targeted for patent protection, with filings made to secure regional rights.
5. How does the patent landscape influence R&D decisions?
A dense patent landscape necessitates careful freedom-to-operate analysis and may influence the choice of chemical modifications or indications pursued.
