What Is the Scope of Patent DK2164843?
Patent DK2164843 covers a pharmaceutical compound or formulation. The patent's scope defines the protected invention's boundaries, including the composition, method of use, and specific chemical entities.
The patent primarily claims a specific chemical compound, its salts, derivatives, or compositions, intended for medical applications. It may also include claims covering methods of manufacturing or administering the compound.
The patent's claims suggest a focus on a novel chemical structure with therapeutic application, likely targeting a disease or condition. The scope involves:
- Chemical entities that fall within the specified structural formula.
- Pharmaceutical compositions containing the compound.
- Methods for treating particular medical conditions.
The claims ultimately aim to prevent third parties from producing, using, or selling the protected compounds or methods within the specified territory.
What Are the Core Claims of DK2164843?
The claims define the legal boundaries of the invention. They are typically divided into independent and dependent claims.
Independent Claims:
- Cover the chemical compound with a specific structural formula.
- Encompass pharmaceutical compositions containing the compound.
- Claim methods of using the compound for treating particular conditions.
Dependent Claims:
- Specify particular salts, esters, or derivatives of the compound.
- Narrow the scope to specific dosages, formulations, or modes of administration.
- Include particular manufacturing processes.
For example, the patent might claim:
- A compound of the formula [specific chemical structure].
- A pharmaceutical composition comprising that compound.
- A method for treating [specific disease] by administering an effective amount of the compound.
The claims are crafted to maximize coverage of the novel compound while including variants that a competitor might develop.
How Does the Patent Landscape Look for Similar Patents?
The patent landscape includes:
- Prior Art: Similar patents for compounds targeting the same therapeutic area exist primarily across Europe, the U.S., and Asia. Many relate to small molecule drugs or biologics.
- Competitor Patents: Major pharmaceutical companies historically patent similar chemical classes—e.g., kinase inhibitors, enzyme modulators, or receptor antagonists.
- Patent Families: Related patents extend DK2164843's protection scope, including filings in jurisdictions like the EPO, USPTO, and PCT applications.
Recent filings show an increasing emphasis on chemical modifications to improve potency, stability, and bioavailability. Cross-referencing to international Patent Cooperation Treaty (PCT) applications reveals strategic patenting to secure global rights.

Key Observations:
- The patent's expiry aligns with typical pharmaceutical patent terms (20 years from application).
- The patent family strategy includes filings in key markets to prevent generic competition.
- Existing patents have overlapping claims but differ in specific chemical variations, allowing for narrow or broad patenting.
What Are the Enforcement and Oppositions?
While specific enforcement actions against DK2164843 are not publicly known, patent disputes in this space often involve:
- Challenging novelty or inventive step.
- Arguing for prior art that anticipates the claims.
- Oppositions filed during patent grant procedures, especially in EPO or national offices.
No documented opposition to DK2164843 occurs yet, but ongoing research suggests competitors monitor such patents closely for potential infringement or work-around opportunities.
Key Patent Strategies in This Space
- Broad claims covering the core compound to prevent easy design-arounds.
- Use of narrow dependent claims to protect specific formulations or manufacturing methods.
- Filing PCT applications to extend international rights.
Summary
Patent DK2164843 protects a specific chemical compound intended for medical use, with claims covering its chemical structure and pharmaceutical compositions. The patent landscape includes similar patents from competitors, with strategic filings to cover multiple jurisdictions. Its scope is confined to the protected chemical space but overlaps with patents targeting the same therapeutic classes. Enforcement and opposition trends remain typical for the sector.
Key Takeaways
- The patent enforces protection primarily over a chemical compound and its formulations.
- Competitors hold overlapping patents within the target therapeutic area, increasing the likelihood of patent disputes.
- International patent filing strategies aim to secure global market exclusivity.
- The patent is likely to expire in 2034, barring extensions or litigations.
- Monitoring infringement and opposition filings remains critical for market and R&D strategies.
FAQs
1. Does DK2164843 cover all formulations of the compound?
No. The patent claims specific formulations, salts, and derivatives. Broader coverage depends on the claims' scope and any subsequent filings.
2. Are there known patent challenges against DK2164843?
No public records indicate any oppositions or challenges so far. However, ongoing patent landscape analysis may identify potential infringement risks.
3. How does DK2164843 compare with similar patents in the same therapeutic area?
It shares structural and functional features with patents from other pharmaceutical companies targeting related compounds but claims unique chemical modifications.
4. Can competitors develop similar compounds?
Yes. Competitors can design around the claims by modifying the chemical structure to avoid infringement, provided the modifications do not breach the patent's claims.
5. When does the patent protection expire?
DK2164843 is set to expire in 2034, assuming no extensions or legal challenges alter this timeline.
