Analysis of Patent 6,489,329: Scope, Claims, and Landscape
What is Patent 6,489,329?
Patent 6,489,329 titled "Methods of treating pathological conditions" was granted by the United States Patent and Trademark Office (USPTO) on December 17, 2002. It covers specific methods of administering a pharmaceutical agent, with a focus on its composition and therapeutic applications.
Patent Details
- Title: Methods of treating pathological conditions
- Inventors: [Name not specified here]
- Assignee: [Name not specified here]
- Filing Date: December 2, 1999
- Issue Date: December 17, 2002
- Application Number: 09/464,576
What are the Scope and Claims?
The patent claims cover methods involving the administration of a specific class of pharmaceutical compounds, primarily aimed at treating certain diseases or disorders. These claims fall into two categories:
Broad Claims
- Methods of treating particular pathological conditions by administering compounds characterized by certain chemical structures.
- Use of these compounds in specific dosage forms and regimens.
Narrow Claims
- Specific provides of chemical compositions, including precise chemical structures.
- Precise methods of formulation, such as doses, administration routes, and treatment durations.
Key Claims Summary
| Claim Type |
Description |
Scope |
| Method of Treatment |
Administering a compound to treat a condition |
Broad; covers any disease responsive to compounds |
| Composition Claim |
Pharmaceutical formulation containing the compounds |
Includes specific formulations and excipients |
| Dosage and Regimen |
Specific doses and administration schedules |

FAQs
-
Can I develop a similar drug after this patent expires?
Yes, once the patent expires, the protected compounds can be used freely, barring other existing patents covering different aspects.
-
Does the patent protect all uses of the compounds?
No, it mainly covers specific therapeutic methods listed in the claims, not all potential uses.
-
Are related patents enforced together?
Not necessarily. Enforcement focuses on specific patents; related patents may have separate legal statuses.
-
What are common strategies to work around such patents?
Developing compounds with different chemical structures or targeting different indications can circumvent existing claims.
-
Can I file a generic version based on this patent?
Only after patent expiry or if the patent is invalidated; legal counsel should review patent claims for infringement risks.
