2.2. Independent Claim Analysis
Claim 1 (Compound Claim)
"An isolated compound comprising [hypothetical structure], wherein R1, R2, R3 are independently selected from [lists of functional groups]."
- Scope: Protects a broad class of compounds based on core structure with variable substituents.
- Implication: Encompasses multiple analogs, enabling extensive freedom for derivation by the patent holder.
Claim 2 (Method of Use)
"A method of treating a neurological disorder comprising administering an effective amount of the compound of claim 1 to a subject."
- Scope: Medical use patent; covers methods utilizing claimed compounds.
- Limitations: Does not specify disease stages or patient populations explicitly, offering broad therapeutic coverage.
2.3. Dependent Claims
Dependent claims specify particular substituents, dosages, or formulations, e.g.:
- Claim 8: "The method of claim 2, wherein the neurological disorder is Alzheimer’s disease."
- Claim 12: "The compound of claim 1, wherein R1 is a methyl group."
These narrow claims carve out specific embodiments, providing fallback positions in litigation.
3. Patentability and Novelty Analysis
