Scope of the Patent Claims
1. Chemical Compound Claims
The core claims define the chemical entity with precise structural features. These claims typically cover:
- A novel compound with a specific molecular formula, functional groups, and stereochemistry.
- Variants and modifications that maintain the compound’s core activity, demarcated by Markush structures.
- Salts, esters, solvates, and prodrugs of the active compound, broadening patent coverage.
Such chemical claims aim to prevent competitors from synthesizing similar molecules that could circumvent patent rights via minor structural modifications.
2. Process Claims
Process claims describe methodologies for synthesizing the compound, including:
- Specific reaction conditions.
- Intermediates used in the synthesis pathway.
- Purification techniques ensuring product quality.
These claims serve to protect proprietary manufacturing processes, creating barriers to generic manufacturing and counterfeit production.
3. Therapeutic Use Claims
Use claims specify:
- The treatment of [target disease/condition] using the compound.
- Administration protocols, dosage forms, and delivery methods.
- Specific patient populations, such as refractory cancers or neurological disorders.
Use claims are critical in patents focused on medical indications, granting exclusive rights to treat particular diseases.
4. Formulation and Delivery Claims
While not primarily the focus, the patent may include claims covering specific formulations—e.g., sustained-release formulations or combinations with other active ingredients—further extending exclusivity.
Patent Term and Validity
DK1877119 enjoys a standard protection period, typically 20 years from filing, with supplementary protection may be applicable depending on local patent laws or regulatory delays.
