Number |
Description / Scope |
| Independent Claims |
3 |
Cover the general chemical formula and broad methods of use. |
| Dependent Claims |
22 |
Narrower claims specify particular substituents, preparation methods, and formulations. |
Sample Independent Claims (paraphrased)
- Claim 1: A heterocyclic compound characterized by specific substituents on a core ring structure, exhibiting activity against a particular receptor.
- Claim 2: A pharmaceutical composition comprising at least one compound as claimed in Claim 1.
- Claim 3: A method for treating a disease state by administering the compound of Claim 1.
Scope Interpretation
- Breadth: The broad formulas in the independent claims cover multiple derivatives, providing extensive territory for potential patent infringement or design-around strategies.
- Limitations: Specific substitutions and synthesis limitations in dependent claims narrow overall scope, protecting particular embodiments.
Claim Construction and Potential Limitations

Frequently Asked Questions
1. What are the core chemical features of the compounds claimed in U.S. Patent 7,087,613?
They involve heterocyclic structures with specific substitution patterns designed for therapeutic activity, particularly receptor modulation with variable functional groups.
2. How does the scope of claims in the '613 patent influence potential patent infringement?
The broad independent claims encompass numerous derivatives, increasing the likelihood of infringement by similar compounds. However, narrow dependent claims may serve as defense boundaries.
3. Are there existing patents that challenge the validity of the '613 patent?
Prior art such as patents filed before 2002 with similar chemical scaffolds could potentially serve as grounds for invalidation if they disclose similar compounds or methods.
4. How does the patent landscape affect market exclusivity for the claimed compounds?
The '613 patent provides market exclusivity until 2026 in the U.S., assuming maintenance and no challenges. Similar patents in other jurisdictions may extend or limit global protection.
5. What are the key strategies for navigating this patent landscape?
Options include developing non-infringing derivatives, licensing, challenging the patent’s validity based on prior art, or seeking orphan drug status to extend exclusivity.
