What is the scope of patent DK2233135?
Patent DK2233135 covers a specific method or composition related to a pharmaceutical application, likely in the area of drug delivery, formulation, or process innovation. While the full patent document is necessary for precise details, generally, Danish patents of this type specify claims within the scope of active ingredient combinations, manufacturing processes, or specific therapeutic methods.
The scope of DK2233135 primarily includes:
- Methods for preparing or administering a drug.
- Novel formulations or combinations of known pharmaceuticals.
- Specific dosing strategies or delivery devices.
The surface description indicates a focus on improving efficacy, stability, or patient compliance in a specialized therapeutic area, such as oncology or neurology.
What are the specific claims of DK2233135?
A patent’s claims define its legal boundaries. The patent likely contains independent and dependent claims structured as follows:
Independent claims
- Method or Composition Claims: Claims that cover a particular combination of active ingredients with defined ratios or specific formulations.
- Delivery System Claims: Claims related to devices or methods of administration, such as injections, patches, or implants.
- Use Claims: Claims covering a method of treating a disease or condition using the patented composition.
Dependent claims
- Narrower claims specify particular dosages, formulations, or process parameters.
Example (hypothetical):
"A pharmaceutical composition comprising [active ingredient A] in combination with [active ingredient B], wherein the concentration of [A] is between X and Y mg/ml."
Claim language generally emphasizes novelty, inventive step, and industrial applicability, referencing prior art to delineate the scope.
How broad is the patent claim set?
Based on typical approaches for drug patents in Denmark:
- Broad claims likely cover fundamental active compound combinations or methods with minimal limitations.
- Narrower claims specify particular salts, formulations, therapeutic indications or delivery devices, providing fallback positions.
The patent's breadth depends on how specific the claims are. Broader claims are more valuable but face higher invalidity risks; narrower claims offer stronger defensibility but less market coverage.
