Without the full text, the precise scope at the claim level remains inferred from typical pharmaceutical patents. Nevertheless, such patents generally aim to secure broad composition and method claims alongside narrow, specific chemical structures.
Claim Analysis
Given standard patent strategies, the claims in BR112014028909 are likely to be:
-
Compound Claims: Covering the novel chemical entities with specified structural features, such as particular heteroatoms, functional groups, or stereochemistry conferring anticancer activity.
-
Pharmaceutical Composition Claims: Including the compound in combination with pharmaceutically acceptable carriers, stabilizers, or adjuvants.
-
Use Claims: Claiming the use of the compound for treating specific cancers, aligning with the intended medical indication.
-
Method of Manufacturing: Detailing synthetic routes to produce the claimed compounds with specific steps, catalysts, or conditions.
-
Optional Claims: Covering variants such as salts, enantiomers, or prodrugs derived from the core compound.
Claim breadth in such pharmaceutical patents often reflects a strategic attempt to balance broad coverage with enforceability. A thorough claim analysis would evaluate whether the invention claims encompass only the specific compound or a class of related compounds, affecting market exclusivity.
