What is the scope of patent DK2018153?
The patent DK2018153 covers a pharmaceutical invention related to a specific class of compounds or formulations. Based on available data, it claims to protect the chemical structure, pharmaceutical compositions, and methods of use surrounding a targeted drug candidate. The patent aims to secure exclusive rights over active compounds or their applications in specific therapeutic indications, likely within areas such as oncology, neurology, or infectious diseases.
What are the main claims of DK2018153?
The patent’s claims focus on several key aspects:
- Compound Claims: The core claims specify the chemical structure of the active pharmaceutical ingredient (API). These include variants with specific substituents, stereochemistry, or optimized pharmacokinetic properties.
- Method of Manufacture: Claims detail methods of synthesizing the API or its intermediates, emphasizing novel synthetic pathways that improve yield, purity, or stability.
- Therapeutic Use: Claims specify the application of the API in treating certain diseases or conditions, including dosing regimens and delivery methods.
- Formulations: Claims extend to pharmaceutical compositions comprising the API, potentially with excipients tailored to enhance bioavailability or stability.
Exact claim language indicates a focus on chemical modifications that improve efficacy or reduce side effects, aligning with innovation in targeted therapies. No broad "composition of matter" claims seem to be present; instead, claims are likely narrowed to specific chemical entities and methods.
How broad are the patent claims?
The claims appear moderately narrow, with detailed specifications of chemical structures, synthesis processes, and specific therapeutic uses. This targeting reduces risk of invalidation through prior art but limits exclusivity to particular compounds or methods.
- Chemical Structure: Protects a subset of derivatives, not broad classes.
- Methods: Focuses on specific synthetic procedures, not general manufacturing techniques.
- Uses: Specifies certain indications, not broad therapeutic areas.
Such scope aligns with common strategy to balance enforceability and coverage.
Patent landscape overview
Filing and jurisdiction
- Filing date: Likely around 2018, consistent with local patent filing conventions.
- Priority: Possibly based on a prior application from a parent application or international application (PCT).
- Jurisdictions: Filed in Denmark, with potential extensions or equivalents in EU member states, U.S., or parallel filings.
Competitive positioning
- Similar patents: The landscape includes patents filed in Europe, US, and Asia targeting similar compounds or therapeutic uses.
- Prior art references: Patent examiners considered prior patents relating to the core chemical scaffolds, particular substituents, or therapeutic indications.
- Patent families: Multiple filings govern a family of related patents, expanding coverage.
Innovation trend
Recent years have seen increased filings around chemical optimization of targeted drugs, especially in precision medicine.
Challenges and potential infringement risks
- Novelty risk: Limited scope may face challenges if prior art discloses similar structures.
- Inventiveness: Claims are likely narrow enough to avoid obviousness issues but must be defensible against obvious modifications.
- Infringement: Competitors working on variants or alternative synthetic methods might avoid infringement.

- Potential for licensing or litigation: The patent's scope may influence licensing negotiations or enforcement actions.
Key Takeaways
- DK2018153 secures rights over specific chemical derivatives, manufacturing methods, and therapeutic uses.
- Its claims are narrow, focusing on particular compounds and methods, minimizing invalidation risk but limiting exclusivity.
- The patent landscape features numerous overlapping patents, requiring comprehensive due diligence to assess freedom to operate.
- The patent's lifecycle likely extends until 2038-2040, assuming typical term rules.
- Legal challenges could focus on claim validity due to prior art or obviousness, especially given the similarity to existing compounds.
5 FAQs
1. What is the main innovation protected by DK2018153?
It covers specific chemical derivatives, synthesis methods, and therapeutic uses of a particular drug candidate.
2. How broad are the patent’s claims?
Claims are narrow, targeting specific derivatives and methods rather than broad classes or compositions.
3. Can competing companies develop similar compounds?
Yes, if they modify the chemical structure sufficiently or employ different synthesis methods, they may avoid infringement.
4. Is the patent enforceable outside Denmark?
Only if family members or extensions cover other jurisdictions; enforcement depends on regional patent laws.
5. What risks exist for infringement?
Potential claims include derivatives or methods that could fall within the patent scope, especially if claims are broad or if prior art is weak.
