Analysis of US Patent 7,977,045: Scope, Claims, and Patent Landscape
What does US Patent 7,977,045 cover?
United States Patent 7,977,045, granted on July 12, 2011, primarily covers a pharmaceutical composition involving a specific chemical compound or formulation. The patent relates to a method of treating certain diseases using a defined active agent, with features including formulation specifics, methods of synthesis, and potential therapeutic applications.
What is the scope of patent claims?
The patent includes a set of independent claims defining the core invention, supported by multiple dependent claims refining specific embodiments.
Independent Claims Overview
- Cover a compound or class of compounds with a specified structure, typically involving a core chemical framework.
- Include claims directed to pharmaceutical compositions containing the claimed compound.
- Encompass methods of treatment involving administering the compound to a patient suffering from a disease.
Dependent Claims
Dependent claims specify variations such as:
- Specific substituents on the core structure.
- Methods of synthesis.
- Dosage forms and routes of administration.
- Target diseases or conditions.
Claim Language Analysis
The claims use functional language to protect the compound’s structure as well as its use in methods of treatment. They avoid overly broad scope by including specific substitution patterns, which limits potential infringing compounds but maintains generality across multiple therapeutic applications.
