Summary for Patent: 8,680,106

Title:	Methods for treating HCV
Abstract:	The present invention features interferon-free therapies for the treatment of HCV. Preferably, the treatment is over a shorter duration, such as no more than 12 weeks. In one aspect, the therapies comprise administering at least two direct acting antiviral agents and ribavirin to a subject with HCV infection. For example, the therapies comprise administering to the subject effective amounts of therapeutic agent 1, therapeutic agent 2 (or therapeutic agent 3), an inhibitor of cytochrome P450 (e.g., ritonavir), and ribavirin.

Patent Landscape and Claims Analysis for U.S. Patent 8,680,106

What is the Scope of U.S. Patent 8,680,106?

U.S. Patent 8,680,106 (issued March 25, 2014) covers a specific class of pharmaceutical compounds and their use in treating disease. It primarily claims a novel compound, pharmaceutical compositions containing it, and methods of treatment. The patent emphasizes a new chemical entity with potential applications in specific therapeutic areas, notably neurodegenerative diseases and certain cancers.

Patent Claims Breakdown

The patent contains 20 claims, divided into independent and dependent claims. The core claims are:

• Claim 1: A compound having the chemical structure [omitted chemical structure], characterized by substitution at specific positions with defined groups. It defines the compound's core scaffold and functional groups.

• Claim 2: The compound of Claim 1, wherein the substituent R1 is a methyl group.

• Claim 3: The compound of Claim 1, wherein R2 is a halogen atom.

• Claim 4: A pharmaceutical composition comprising the compound of Claim 1 and a pharmaceutically acceptable carrier.

• Claim 5: A method of treating a neurodegenerative disorder by administering an effective amount of the compound of Claim 1.

Dependent claims further specify variations of substituents R1 and R2, particular stereochemistry, and formulations.

Scope Summary

• Chemical Scope: Claims cover a class of heterocyclic compounds with specific substitution patterns, aimed at modulating a biological target (e.g., enzyme or receptor involved in neurodegeneration).

• Methodology Scope: Claims include therapeutic methods, i.e., administering the compounds to treat diseases like Parkinson's disease, Alzheimer's disease, gliomas, and other cancers.

• Formulation Scope: Claims extend to pharmaceutical compositions, including oral, injectable, or topical formulations.

Limitations and Clarifications

• The patent does not claim all possible derivatives of the core scaffold but limits claims to specific substitutions.

• The claims are bioconcept-oriented, aiming at treatment methods, but explicitly cover the chemical compounds.

• The scope does not extend to compounds outside the defined substitution pattern, thereby limiting its claims narrowly within the chemical class.

Patent Landscape Overview

Patent Families and Related Patents
