Claims Analysis
1. Independent Claims
The independent claims of the '101 patent delineate the broadest protections:
-
Chemical Structure Claims: These claims define the precise structural formulae of the claimed compounds using chemical nomenclature and Markush structures. For example, a claim may specify a compound comprising a core scaffold with particular substituents or substituent positions.
-
Method of Use: Claims may extend to administering these compounds for treating specific diseases or conditions, such as certain cancers, inflammatory disorders, or viral infections.
-
Process Claims: Inclusion of novel synthesis methods, emphasizing unique reaction conditions or catalytic processes that distinguish the patent from prior art.
Example (hypothetical): A claim covering “A compound of formula I wherein R1, R2, R3 are selected from the group consisting of...”, establishing the boundaries of scope for chemical variants.
2. Dependent Claims
Dependent claims refine the protection, adding limitations such as:
-
Specific substituent groups (e.g., halogens, alkyl groups).
-
Particular salts, polymorphs, or pharmaceutical compositions.
-
Dosing methods, treatment algorithms, or combination therapies.
3. Claim Strategy
The patent employs both broad and narrow claims—broad claims safeguard expansive chemical classes, while narrower claims target specific compounds or applications, providing layered protection against design-around strategies.
