What is the scope of DK1556389?
DK1556389, filed by a pharmaceutical entity in Denmark, covers a specific pharmaceutical compound or formulation. Its scope primarily encompasses the composition of matter, methods of use, and possibly methods of manufacture related to a particular drug or pharmaceutical process.
The patent's claims focus on a novel chemical entity or an innovative application of an existing compound, aiming for therapeutic efficacy against targeted indications. The scope often extends to:
- The chemical structure of the compound.
- Pharmaceutical compositions containing the compound.
- methods of preparing the compound.
- Therapeutic uses for specific conditions or diseases.
Without access to the complete patent document, typical scope elements include pharmaceutical salts, formulations, delivery mechanisms, and specific treatment protocols covered.
What are the key claims of DK1556389?
Based on standard pharmaceutical patent drafting and the available information, the claims likely include:
- Compound Claim: Patent claims on the chemical structure of the active pharmaceutical ingredient (API).
- Use Claim: Claims covering the application of the API for treating specific diseases or medical conditions (e.g., cancer, neurological disorders).
- Formulation Claim: Claims on pharmaceutical compositions incorporating the API with carriers or excipients.
- Method of Production: Claims on processes to synthesize the API or formulations.
- Combination Claims: Claims covering the API used in combination with other pharmaceuticals.
For example, if the patent claims a novel compound X with a specific structure, it may also include claims for its salts, solvates, and esters. Use claims for treatment typically specify dosage regimes, delivery modes, or administration routes.
