What Is the Scope of Patent 7,214,696?
1. Core Chemical and Therapeutic Focus
The patent claims relate chiefly to a chemical compound or a class of compounds characterized by specific structural features, with claims encompassing:
- Structural formulae (e.g., a heterocyclic scaffold)
- Method of synthesis
- Pharmaceutical compositions containing the compound
- Therapeutic uses (notably, treatment of [specific disease or disorder], e.g., neurological conditions, cancers, infections)
Example: The patent might claim compounds of formula (I):
Chemical structure (e.g., a heterocycle with specific substituents)
which exhibit activity against target biological pathways such as kinase inhibition, receptor modulation, or enzyme suppression.
2. Types of Claims
A. Composition of Matter
- Primary claim type: Covers the chemical entity or a group of related compounds.
- Scope: Typically broad, including substituted derivatives within certain structural parameters.
B. Method of Use Claims
- Claims directed to methods of treating diseases using the compound.
- Examples include administration protocols, dosages, or formulations.
C. Method of Synthesis
- Potential claims covering specific synthetic routes for obtaining the compound.
- Generally narrower but essential for protecting proprietary processes.
3. Claim Scope Particulars
The claims' scope hinges on:
- The chemical structure definitions embedded in the claims.
- The functional features such as binding affinity or pharmacokinetic properties.
- The indications targeted (e.g., cancer, neurodegeneration).
Notably:
- The claims might be narrower if specific substituents are mandatory.
- Broad claims could encompass a wide class of derivatives but are often limited by prior art or patent limitations.

FAQs
Q1: Can the patent claims be broadened through litigation or reissue?
A: Generally, claims can be challenged via patent examination procedures or reissue petitions, but broadening rights post-grant is limited. Litigation could narrow or uphold key claims, depending on prior art.
Q2: How does the patent's scope protect against generic competitors?
A: Its patent claims cover specific compounds and uses, which could prevent generics from entering the market with identical molecules for the claims’ scope. However, structurally similar but non-infringing derivatives can challenge this.
Q3: Are method-of-use claims enforceable?
A: Yes, method-of-use claims can be enforced if the patented method is actively used or marketed. They often cover specific therapeutic indications.
Q4: What is the relevance of patent classification codes?
A: Classification codes like CPC C07D (heterocyclic compounds) and A61K (medical preparations) help identify the patent’s technical domain, aiding search and clearance activities.
Q5: How does this patent landscape impact R&D strategies?
A: Companies must navigate existing patents when developing similar compounds, possibly innovating around claims or licensing patents to avoid infringement.
