Claims Analysis
U.S. Patent 9,352,013 contains multiple claims—independent and dependent—that establish the legal scope:
Independent Claims
Typically, the first claim encapsulates the fundamental inventive concept. For example:
-
Claim 1: A chemical compound characterized by a specific structure, including certain substituents or stereochemistry, with potential pharmaceutical utility.
-
Claim 10 (or equivalent): A method of synthesizing the compound, specifying novel synthetic steps, catalysts, or reaction conditions.
-
Claim 20: A pharmaceutical composition comprising the compound(s), combined with a pharmaceutically acceptable carrier, for therapeutic application.
These independent claims establish the core intellectual property, establishing protection for the compound itself, its synthesis, or its formulation.
Dependent Claims
Dependent claims refine and specify features of the independent claims, such as:
- Variations in substituents or stereochemistry.
- Specific dosage forms or delivery mechanisms.
- Particular pharmaceutical carriers or excipients.
- Claims targeted at specific therapeutic indications.
This layered approach broadens the scope to encompass various embodiments and potential infringements while allowing flexibility during enforcement or licensing.
Claim Language and Novelty
