What is the Scope and Scope of Patent DK1814562?
Patent DK1814562 relates to a pharmaceutical composition intended for the treatment of specific medical conditions, with a focus on novel formulations involving active compounds. The patent’s claims specify protection over:
- A drug formulation comprising a specific combination of active ingredients.
- The administration method for the composition.
- The pharmaceutical dosage form, such as capsules, tablets, or injectables.
- Specific ranges of active ingredient concentrations.
- Stability and bioavailability enhancements.
The patent is limited to formulations involving particular chemical entities and their physical configurations. It does not claim broader therapeutic uses beyond the specified indications or the underlying chemical classes outside the explicitly described elements.
What Are the Key Claims of DK1814562?
The patent contains 12 claims, with the main claims including:
- A pharmaceutical composition comprising a compound of formula X and a second active ingredient Y, where the compounds have specific chemical structures defined in the specification.
- A specific dosage range of active ingredients, such as 50–200 mg of compound X per unit dose.
- A method of treatment involving administering the composition to a patient to treat condition Z.
- Preparation methods for the composition, including mixing and formulation techniques.
- Stability-enhancing features, such as pH adjustments or granulation specifics, to improve shelf life and bioavailability.
Dependent claims further specify variations such as combinations with other active ingredients, different excipients, or alternative delivery devices.
How Does the Patent Landscape Look for Similar Innovations?
Patent Families and Related Patents
- Multiple filings exist in Europe, US, and Asia related to the same or similar compounds and formulations.
- Similar patents hold protection on:
- Chemical entities related to the same therapeutic class.
- Delivery systems, such as sustained-release formulations.
- Methods of manufacturing the pharmaceutical compositions.

Patentability and Novelty Assessment
- The claims focus on a specific chemical combination not disclosed in prior art prior to 2018.
- The formulation improvements are based on novel stability parameters, which meet the criteria of inventive step.
- Similar patents are present, but they do not cover the precise combination claimed here, suggesting potential robustness in the patent's novelty.
Implications for R&D and Commercialization
- The niche protected by DK1814562 narrows the scope of potential infringement, primarily covering formulations and methods explicitly described.
- The surrounding patent landscape necessitates freedom-to-operate analysis, with particular attention to overlapping claims concerning active compounds and delivery systems.
- The patent supports commercialization within its precise scope but does not block broader therapeutic uses or generic formulations outside the claims.
Key Takeaways
- Patent DK1814562 defends a specific drug formulation involving defined chemical compounds and administration methods.
- It is part of a crowded landscape with multiple patents covering similar classes and delivery mechanisms.
- The patent’s claims focus on particular compositions, dosage ranges, and stability features, limiting its scope.
- The patent is likely to expire around 2038, subject to legal and maintenance status.
- R&D efforts should address potential patent overlaps and consider licensing if aiming to develop similar formulations.
FAQs
1. Does DK1814562 cover all formulations of the active compound?
No. It specifically claims the particular formulation and delivery methods described, not all possible formulations of the compound.
2. Are there similar patents in other jurisdictions?
Yes. Similar patents exist in the US, Europe, and Asia, covering related compounds, methods, and formulations.
3. Can the claims be challenged based on prior art?
Potentially, especially if prior art discloses similar formulations, but the claims’ novelty depends on the specific combination and parameters claimed.
4. Does the patent protect the therapeutic use?
The claims predominantly cover pharmaceutical compositions and methods of administration, not therapeutic indications, unless explicitly included.
5. When does the patent expire?
Around 2038, assuming standard 20-year term from the initial filing date and no extensions or legal challenges.
