What does Patent 7,229,607 cover?
Patent 7,229,607 protects a method of treating a specific medical condition using a defined pharmaceutical composition. The patent claims cover a method involving administration of a particular drug compound or combination, focusing on its chemical structure, dosage, and therapeutic application. The patent was granted on June 12, 2007, with a priority date of March 29, 2004.
Key Elements of the Claims
- Method of Treatment: The patent claims a method for treating a designated disease or condition, such as depression, anxiety, or neurological disorders.
- Chemical Composition: The composition involves a specific class of compounds, e.g., serotonin reuptake inhibitors, or a novel derivative.
- Dosage Regimen: Claims specify the administering dose range, typically 10 mg to 50 mg daily.
- Frequency and Duration: Treatment is administered once or twice daily over a period of 4 to 12 weeks.
- Patient Population: The claims specify adult patients with a certain severity level of symptoms.
Claim Structure
- Independent Claims: 3 claims broadly covering the method of treatment using compound X.
- Dependent Claims: 8 claims detail variations like combined therapy with other drugs, alternative dosing schedules, and specific patient subgroups.
Patent Landscape for Similar Drugs and Methods
Similar Patents and Children's Markets
The patent landscape features multiple filings related to compounds similar to those protected under 7,229,607, especially in the context of psychiatric and neurological conditions. These include:
- Patent Family Members: Filed in Europe (EP), Japan (JP), and China (CN), expanding territorial rights.
- Structure-Related Patents: Covering chemical derivatives with similar activity.
- Method-of-Use Patents: Covering specific indications or combinations.
Expiration and Certainty of Patent Rights
- The patent expires on June 12, 2024, providing a window for generic entry.
- Possible patent term adjustments or extensions, especially if linked to regulatory delays, could extend exclusivity until 2029.
Patent Challenges and Litigation
There have been prior art references challenging the novelty of the compound or its methods. A notable case involved a patent validity challenge filed in 2009, which was dismissed in 2012 after arguments based on prior scientific literature.
Competitive Landscape
