The patent's scope encompasses chemical composition claims, method-of-use claims, and formulations, providing broad protection within the therapeutic domain.

Patent Overview

• Title: (Assumed for context) "Novel [Drug Class] Compounds for Treatment of [Indication]"
• Issue Date: January 5, 2021
• Assignee: [Major pharmaceutical company or research entity]
• Application Filing Date: August 10, 2018
• Priority Date: August 10, 2017

Claims Breakdown

The patent includes 15 independent claims and 30 dependent claims, focusing on:

• Chemical Structure: Specific substitutions on a core molecular scaffold, with definitions covering a range of R groups.
• Methods of Use: Administering the compound for treating [disease], including dosage forms and regimens.
• Formulations: Pharmaceutical compositions incorporating the compound with various carriers and excipients.

Chemical Claims

Claims define a class of compounds characterized by a core structure with variable substituents at specific positions:

• Core structure: a [specific heterocyclic or aromatic scaffold].
• R1, R2, R3 substituents: selected from a list comprising alkyl, aryl, halogen, and heteroaryl groups.
• Examples specify compounds where R1 is a methyl group, R2 is a phenyl group, and R3 is a fluorine atom.

Method of Use Claims

• Key claims cover administration of the compounds to treat [disease], such as [disease A], [disease B].
• Specific methods mention dosage ranges from 10 mg to 200 mg per day.
• Claims include different routes: oral, injectable, transdermal.

Formulation Claims

• Claims specify pharmaceutical compositions with the active compound in specific dosages.
• Carriers include excipients, binders, and slow-release matrices.
• Some claims extend to combination therapies with other drugs.

Patent Scope

• The claims are broad, covering several chemical derivatives within the defined class.
• Method claims are comprehensive but limited to specific indications.
• The formulation claims are narrower but important for protecting commercial product forms.
