What Are the Main Claims of the '770 Patent?

Claims Overview

• Independent Claims:
  Typically cover the core compound(s), their synthesis routes, and fundamental therapeutic use.

• Dependent Claims:
  Narrower claims refining the scope, such as specific substitutions, formulations, or dosage forms.

Below is a summarized breakdown based on the patent document (assuming typical claim structures; actual language from the patent is necessary for complete accuracy).

Type of Claim	Subject Matter	Scope	Examples
Independent Claims	Core chemical compound and method of use	Broad; encompasses novel compounds, e.g., a chemical formula with substituents X, Y, Z	E.g., a compound comprising a pyrimidine core with specific substituents
Dependent Claims	Specific variants, formulations, dosages	Narrower; includes specific substitutions, salt forms, pharmaceutical compositions	E.g., a compound with a particular side chain extended group

Sample Claims (Hypothetical based on similar patents)

• Claim 1: A chemical compound comprising a core structure of [specific chemical formula] with substitutions X and Y.

• Claim 2: The compound of claim 1, wherein the substituents are [specific groups].

• Claim 3: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.

• Claim 4: A method of treating [disease], comprising administering an effective amount of the compound of claim 1 to a subject.
