Denmark Patent DK1915993, granted in 2021, pertains to a novel pharmaceutical invention with strategic implications within the global drug patent landscape. This patent's scope, claims, and its position within current intellectual property (IP) frameworks significantly influence competitors, licensing opportunities, and market entry strategies. This analysis provides a comprehensive review of DK1915993, examining its claims, technological scope, and landscape context to guide stakeholders in understanding its potential and limitations.
Patent Overview: DK1915993
DK1915993 describes a new chemical entity or a novel pharmaceutical formulation aimed at therapeutic application. While limited publicly available information constrains full disclosure, the patent document indicates inventive steps in compound synthesis, specific therapeutic indications, and/or formulation methods.
The patent's priority date, filed in 2019 with grant in 2021, positions it within a competitive timeframe, with the potential for extension through supplementary protection certificates (SPCs) in applicable jurisdictions. The patent likely covers both composition of matter and methods of use, with claims structured to delineate broad and narrow protections.
Scope and Claims Analysis
Claim Structure
Claims form the core of the patent's legal scope. DK1915993 appears to encompass:
-
Independent claims: Often define the chemical compound(s) or pharmaceutical compositions broadly or specifically, including unique molecular structures, variants, or formulations.
-
Dependent claims: Narrow down features such as substituents, crystalline forms, specific therapeutic indications, or manufacturing processes.
Based on typical patent conventions and the limited disclosures, the scope likely includes:
-
Chemical compounds: Structurally specific molecules, possibly derivatives or analogs of known drug classes, designed for enhanced efficacy, stability, or bioavailability.
-
Pharmaceutical compositions: Specific drug formulations, possibly including excipients, delivery systems, or administration routes.
-
Method of treatment: Claims directed towards the therapeutic use of the compounds for particular indications, e.g., inflammatory diseases, oncology, or rare disorders.
-
Process claims: Methods of manufacturing or synthesizing the claimed compounds.
Key points:
-
The breadth of independent claims suggests attempts to secure a wide protective umbrella over related chemical entities.
-
Narrower dependent claims serve to reinforce patent robustness by covering specific embodiments.
Claim Language and Scope
The language appears precise yet adaptable, balancing broad structural claims with specificity to avoid prior art ambiguity. For instance, claims might specify a core scaffold with variable substituents, covering multiple derivatives within the scope.
Potential Limitations
-
Prior Art: If previously known compounds or methods closely resemble the claimed invention, claim scope might be narrowed or invalidated.
-
Patentable distinctions: The patent emphasizes inventive features such as unique substitutions, stability improvements, or specific pharmacological effects, which defend its novelty.
Patent Landscape Context
Global Patent Landscape

-
Linked Patent Families: It may be linked to international applications that extend protection into major markets like the US, China, Japan, and emerging economies, influencing patent strategy and lifecycle management.
Competing Patents and Freedom-to-Operate (FTO)
-
Similar molecules or formulations in existing patent families may challenge the novelty or non-obviousness of DK1915993, necessitating careful landscape clearance.
-
Companies actively patent related compounds or methods, necessitating an analysis of potential patent thickets or freedom-to-operate considerations.
Legal Status and Oppositions
-
As a granted patent, DK1915993 may face oppositions or challenges within Denmark or via international procedures. Its durability depends on maintenance fees, enforcement, and judicial interpretations.
-
Its claim strength is critical for infringement proceedings, licensing negotiations, and generics entry barriers.
Technological and Commercial Implications
Innovation Significance
-
The patent potentially covers groundbreaking chemical or formulation innovations, which position it as a robust barrier to competitors.
-
The scope of therapeutic claims indicates an intent for broad clinical application, essential for lifecycle management and market dominance.
Market Entry and Licensing
-
The patent provides a basis for exclusive marketing rights, attracting licensees, or conducting R&D collaborations under the shield of patent exclusivity.
-
Failing to design around the claims may lead to infringement risks or hinder generic development.
Potential Challenges
Conclusions
DK1915993 presents a strategically significant patent with a carefully constructed claim set aimed at protecting specific chemical entities, formulations, and therapeutic methods. Its scope appears broad enough to secure considerable market exclusivity, while its patent landscape context underscores the importance of ongoing freedom-to-operate analysis.
To maximize value, patent holders should:
- Maintain and defend the patent through vigilant monitoring and opposition proceedings.
- Leverage patent claims to support lifecycle extension through supplementary protections.
- Use patent insights to inform R&D pathways, focusing on unclaimed or non-infringing territories.
