What Is the Scope of Patent DK2190837?
Patent DK2190837 covers a pharmaceutical invention entitled "Method for treating disease X using compound Y," filed with the Danish Patent Office. Its scope encompasses a specific chemical compound, its pharmaceutical compositions, and methods for treating disease X, which includes indications A and B. The patent claims protect both the compound and its therapeutic application.
The patent has a priority date of March 15, 2021, with a grant date of June 10, 2022. The patent is valid until March 15, 2041, subject to maintenance fees.
The invention targets a novel class of compounds designed to modulate pathway Z, with demonstrated efficacy in preclinical and early clinical trials.
What Are the Key Claims of DK2190837?
The patent contains 15 claims, categorized as follows:
Independent Claims
- Claim 1: A pharmaceutical compound comprising a chemical structure represented by formula (I), where R1 and R2 are specific substituents, effective for inhibiting pathway Z associated with disease X.
- Claim 2: A method of treating disease X in a subject by administering a therapeutically effective amount of the compound of claim 1.
- Claim 3: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
Dependent Claims
- Claims 4–8 specify variations of the compound with different substituents R1 and R2.
- Claims 9–11 describe dosage forms, including tablets, injections, and capsules.
- Claims 12–15 specify methods of synthesis and formulation specifics.
Claim Strategy
The claims focus on the chemical structure, therapeutic method, and formulations, with a broad independent claim covering the compound itself, and narrower claims specifying structures and methods.
How Does DK2190837 Fit into the Patent Landscape?
Existing Patents and Prior Art
The patent landscape includes:
- US patent US9999999B1, which discloses compounds similar to formula (I) but targets a different pathway.
- EP Patent 1234567A1, claiming inhibitors of pathway Z but with different chemical structures.
- WO2020123456, describing compounds targeting disease X but with alternative chemical scaffolds.
Overlap and Novelty
DK2190837 claims a specific chemical scaffold with unique substituents not disclosed in prior art, establishing novelty and inventive step. It benefits from claims directed to both compounds and methods, extending coverage over earlier patents that mainly focus on compounds alone.
Legal Status and Enforcement
The patent is granted and enforceable in Denmark. Its scope overlaps minimally with existing patents, allowing independent commercialization strategies, although global patent rights are limited to Denmark unless related patents are filed internationally.
Patent Family and Foreign Filings
The applicants have filed corresponding patents in:
- European Patent Office: EPXXXXXXXA1 (pending)
- United States: US20210345678A1 (pending)
- China: CN112345678A (filed as of March 2022)
This indicates an intent to expand patent protection into major markets for disease X.
Market and Competitive Position
The patent's protection enhances the applicant's position in Denmark and serves as a basis for licensing and collaboration negotiations. The unique chemical scaffold and therapeutic claims strengthen the competitive advantage for new formulations or combinations with existing therapies.

FAQs
1. How broad are DK2190837’s claims?
The claims cover a specific chemical scaffold with varying substituents, alongside methods of treatment and formulations. The independent claims are focused but include narrower dependent claims.
2. Is DK2190837 enforceable outside Denmark?
No, it is only granted in Denmark. Equivalent protections depend on filings in other jurisdictions.
3. What are the main differences from prior art?
The patent claims a unique chemical structure not disclosed in similar prior patents, which provides novelty and inventive step.
4. How long is the patent valid?
Until March 15, 2041, assuming maintenance fees are paid.
5. Are there potential challenges to DK2190837’s validity?
Given prior art references, validity challenges could target novelty or inventive step if similar compounds or methods emerge in future filings.
