Analysis of United States Patent 9,657,003: Scope, Claims, and Patent Landscape
What is the Scope of Patent 9,657,003?
United States Patent 9,657,003 (issued on May 23, 2017) covers certain methods and compositions related to a specific class of compounds and their therapeutic applications, particularly in the treatment of diseases such as cancer. The patent claims to protect both the compounds themselves and their use in pharmaceutical compositions, including methods for inhibiting specific biological targets.
The scope includes:
- Novel chemical entities, namely specific small molecules with particular structural features.
- Methods for synthesizing these compounds.
- Methods for using the compounds in treating diseases involving abnormal cell growth or proliferation.
- Pharmaceutical compositions comprising the compounds.
The claims focus on chemical structures characterized by particular substitutions on core scaffolds, aiming to target specific biological pathways, notably kinase inhibition.
What Are the Specific Claims?
The patent contains 24 claims divided into independent and dependent claims. Key claims include:
- Claim 1 (independent): Defines a compound with a specified core structure where R1 and R2 are independently hydrogen or certain substituents, and further specifies double-bond configurations and substitutions on aromatic rings.
- Claim 2: Extends Claim 1 to include salts and pharmaceutical compositions of the compounds.
- Claim 3-6: Cover methods of using the compounds to treat cancer by administering an effective amount to a patient.
- Claim 7-10: Describe methods of synthesizing the compounds.
- Claims 11-24: Focus on specific compounds with defined substituents, related derivatives, and their pharmaceutical uses.
The claims emphasize structural specificity, often narrowing scope to particular substituents, which impacts manufacturing and patent infringement considerations.
