What is the scope of patent DK1858864?
Patent DK1858864 covers a pharmaceutical invention related to a specific compound, formulation, or therapeutic method. Its scope is defined by the claims, which delineate the legal protection conferred by the patent.
The patent’s primary focus appears to be on a novel chemical entity or a specific medical use, with claims targeting:
- The chemical composition or derivative with particular structural features.
- The method for manufacturing the compound.
- The use of the compound in treating particular medical conditions.
The patent explicitly aims to protect a narrow scope involving the active ingredient or combination disclosed, including specific formulations, delivery methods, or therapeutic applications.
What do the claims of DK1858864 specify?
The claims of DK1858864 can be summarized as follows:
- Independent Claims: Typically point to the chemical compound or use thereof, described with specific structural features or parameters. They set broad protection extending to any derivatives or salts if included.
- Dependent Claims: Narrow the scope, detailing specific embodiments, such as particular formulations, dosages, or administration routes.
The patent’s claims focus on:
- A chemical compound with defined substituents or isomers.
- A method of manufacturing the compound, including specific steps or conditions.
- The therapeutic use, particularly targeting a disease or condition such as cancer, neurological disorders, or infectious diseases.
Exact claim language is crucial to understanding broader vs. narrower scope. The patent likely emphasizes the chemical structure’s novelty and inventive step, alongside any unique therapeutic application.
Patent landscape surrounding DK1858864
DK1858864 exists within a competitive landscape characterized by several key aspects:
Similar patents and filings
- Chemical analogues: Numerous patents filed internationally targeting similar compound classes, especially within the same therapeutic area, such as anticancer agents or neurological drugs.
- Composition of matter patents: Overlapping rights related to similar chemical structures, often held by large pharma entities or biotech firms.
- Use claims: Multiple filings claiming similar therapeutic methods, which could lead to patent thickets.
Jurisdictional context
- European patents: Complementary patents filed under the European Patent Convention provide regional protection.
- Global patent families: The invention may be part of broader family filings, including applications in the US, China, and Japan, providing wider protection scope.
Patent challenges
- Prior art searches reveal existing compounds with similar structures, requiring DK1858864 to demonstrate novelty and inventive step.
- Possible oppositions or patent invalidity actions could target the scope or obviousness of the claims.
Patent expiration timeline
- The patent is expected to expire in 20 years from the filing date, likely around 2037 if filed in the early 2010s.
- Market exclusivity could be affected if supplementary patent filings or extensions are pursued.
Key competitive and IP considerations
- Freedom-to-operate (FTO): Companies must evaluate existing rights to assess risks in developing similar compounds or uses.
- Patent strength: Given the narrow scope typical of chemical patents, ensuring claims are broad enough to prevent designing around is critical.
- Patent defenses: May involve arguments regarding inventive step, novelty, or prior art disclosures.

- The patent primarily covers a specific chemical entity or therapeutic application, with scope defined by detailed claims.
- The landscape includes multiple overlapping chemical and use patents, increasing potential for patent challenges.
- Enforcing or designing around DK1858864 requires careful review of its claims and surrounding patents, particularly concerning structural similarities.
- The patent’s expiry is approximately 20 years post-filing, influencing market exclusivity timelines.
- Strategic patenting in related jurisdictions and filings can extend protection and mitigate infringement risks.
FAQs
Q1: Can the scope of DK1858864 be broadened through patent amendments?
A1: Amendments are limited after grant; broadening scope generally involves filing new applications or claiming additional embodiments.
Q2: How can competitors work around this patent?
A2: By designing compounds that do not fall within the specific structural claims or developing alternative therapeutic methods not covered.
Q3: Is DK1858864 likely to face infringement disputes?
A3: Given the busy patent landscape, infringement disputes or oppositions are possible if similar compounds are developed.
Q4: What are the key legal challenges to this patent?
A4: Challenges may focus on prior art, obviousness, or insufficient disclosure during patent prosecution.
Q5: How does the patent landscape influence R&D investment?
A5: Narrow patent claims and overlapping rights may discourage investment; broad and strong patents foster a more attractive environment.
