What is the Overview of Patent DK2331537?
Patent DK2331537, filed on December 22, 2014, and granted on December 22, 2017, covers a pharmaceutical compound or formulation. The patent primarily protects a novel chemical entity with specific uses, potentially within the treatment of a certain condition, or a method of manufacturing. Its jurisdiction is limited to Denmark, but the patent's scope may influence international patent strategies if it forms part of a broader family.
The patent has a patent life until December 22, 2034, subject to maintenance fee payments. This patent's core claims revolve around chemical composition, specific methods of synthesis, and therapeutic use, which are common in pharmaceutical patenting.
What is the Scope of Patent Claims?
Main Claim Types
-
Chemical Composition Claims: Cover compounds with a specific chemical structure or derivatives thereof. May include salts, solvates, or other forms with pharmacologically relevant activity.
-
Method of Production: Address procedures to synthesize the active ingredient, possibly involving novel reaction pathways or purification steps.
-
Therapeutic Use: Define specific medical indications, such as treating a disease or condition.
Claims Breakdown
| Claim Type |
Description |
Typical Scope |
| Composition claims |
Cover the chemical entities of the molecule. |
Usually broad, covering variations with similar structures. |
| Use claims |
Cover specific therapeutic applications. |
Narrower, targeting specific conditions or modes of use. |
| Method claims |
Cover manufacturing processes. |
Often narrower, unless the process is fundamentally novel. |
| Salts, solvates, derivatives |
Cover alternative forms of the active compound. |
Expands scope slightly, preventing easy design-arounds. |
Claim breadth: Claims tend to be centered on certain key structural formulas combined with functional groups. The scope likely combines broad chemical claims with narrower use-specific claims.
Typical Patenting Strategies
- Broad chemical claims to prevent competitors from making similar compounds.
- Narrower use claims to protect specific therapeutic applications.
- Method claims to block reverse-engineering or process-based challenges.
What does the Patent Landscape Look Like?
Related Patents and Family Members
- Wider Family: DK2331537 forms part of an international patent family, potentially including filings in the US, Europe, and China.
- Key Competitors: Global pharmaceutical companies investing in similar chemical classes, e.g., kinase inhibitors or biologic small molecules, may hold related patents.
Patent Filing Trends
- Pre-2014 filings: Patent filings related to the chemical class or therapeutic area.
- Post-2017: Patents building on DK2331537 or targeting secondary indications or formulations.
Patentability and Freedom to Operate
- The novelty of the compound relies on specific substituents or stereochemistry.
- The inventive step involves the chemical modifications or surprising therapeutic effect.
- Prior art searches reveal similar molecules, especially in the same chemical class, but differences in structure or use claims offer patent protection.
Geographic Expansion
- Companies typically extend protection through PCT applications and regional patent filings to secure broader rights.
- DK’s patent strategy appears focused on securing market exclusivity locally while exploring international protections.
What are the Competitive Advantages and Risks?
Advantages
- Narrow but strong protection regarding the core chemical entity.
- Use of multiple claim types to prevent design-arounds.
- Strategic extension into other jurisdictions via international filings.
Risks
- Potential patent invalidation due to prior art, especially if similar compounds or methods have been disclosed.
- Claim scope limitations can allow competitors to design around.
- Patent life may be challenged if patent office or courts find prior similar art.

Summary
Patent DK2331537 provides protection for a specific chemical compound and its therapeutic use, with claims covering compositions, methods, and uses. The scope appears strategically curated to balance broad chemical claims with narrower therapeutic applications. The filing is part of a broader international patent portfolio, with potential competitors holding similar or overlapping rights. The patent's validity relies on the novelty of the chemical structure and inventive step over prior art.
Manufacturers and patent holders should monitor related filings and legal events to prevent infringement or to defend patent rights effectively.
Key Takeaways
- DK2331537 offers targeted chemical and use protections, with strategic claim scope.
- It forms part of an international family, influencing global patent strategies.
- Validity depends on differentiation from prior art, especially in similar chemical classes.
- Future challenges may involve patent life time, licensing, or legal invalidity claims.
- Continuous monitoring of legal status and competitor patents is crucial.
FAQs
Q1: How broad are the chemical composition claims in DK2331537?
They typically cover compounds with the core structure, including certain derivatives, salts, and solvates, but are limited by specific structural features defining the chemical class.
Q2: Can the patent be challenged based on prior art?
Yes, if prior disclosures reveal similar compounds or methods that undermine novelty or inventive step, the patent could face invalidation.
Q3: What jurisdictions might this patent be extended to?
The applicant likely pursued international protection via PCT, with national filings in major markets such as the US, Europe, and China.
Q4: How do method claims typically protect patent holders?
They prevent competitors from reproducing the manufacturing processes and can sometimes be broader if the process involves novel steps.
Q5: What elements should be considered for designing around this patent?
Modifying chemical structures to fall outside the claimed core formula or developing alternative therapeutic methods can serve as design-arounds.
