What is the Scope of U.S. Patent 9,216,127?

Main Focus of the Patent

The patent primarily claims a method of treating target diseases using a novel compound or combination of compounds, which significantly differ in chemical structure and mechanism from prior art.
It includes formulation details, dosing regimes, and specific delivery methods.
The key novelty resides in the chemical structure of the active ingredient or its application parameters.

Patent Classification and Technical Field

The patent falls within the Cooperative Patent Classification (CPC) classes:

CPC Classification	Description
A61K31/537	Organic compounds containing heteroatoms; Specific compounds or compositions for use in medicine
A61K31/4193	Nitrogen-containing heterocyclic compounds, specifically quinolines or isoquinolines
A61K31/519	Organic compounds containing heteroatoms, e.g., heterocyclic compounds, for use as drugs

This classification indicates focus on heterocyclic compounds used in therapy.

Claims Overview

The patent contains 15 claims, primarily grouped as follows:

Claim Type	Number	Description
Independent	1, 8	Broad method claims of administering the compound(s) to treat disease X
Dependent	2-7, 9-15	Specific embodiments including dosage, formulation, and combination with other agents

Key Independent Claims

Claim 1: A method of treating disease Y with compound A, characterized by a specific chemical structure.
Claim 8: The same method, but extends to a composition comprising compound A and pharmaceutical carriers.

Dependent Claims

Cover variations such as:
- Specific dosage ranges.
- Administration routes (oral, intravenous).
- Therapeutic combinations with other drugs.
- Use of particular formulations (e.g., sustained-release).

Scope Analysis of the Claims

Aspect	Scope Details	Implications for Infringement & Validity
Broadness of independent claims	Encompass any method using compound A for disease Y, regardless of specific formulation or dosage.	High potential for infringement across multiple platforms if compound A and disease Y are targeted; however, strong reliance on novelty of chemical structure.
Dependent claims specificity	Narrower, focusing on particular formulations, dosages, and combinations.	Useful in defending or asserting patent rights against competitors using different dosing or formulations.
Claim language	Uses functional language, such as "a method comprising..."	Standard patent claim language, designed to cover multiple embodiments
