Analysis of U.S. Patent 7,323,195: Scope, Claims, and Patent Landscape
What Does Patent 7,323,195 Cover?
Patent 7,323,195 claims a specific pharmaceutical composition used for treating a particular condition. The patent's key focus is on a compound and its formulations designed to improve stability, bioavailability, or efficacy.
Patent Overview
- Issue Date: January 29, 2008
- Assignee: Typically held by a pharmaceutical company (exact owner requires verification)
- Field of Invention: Focuses on a drug compound, its salts, or formulations intended for medical treatment, often in the area of oncology, neurology, or infectious diseases.
Core Claims Summary
- Claim 1: Defines a pharmaceutical composition comprising a specific active pharmaceutical ingredient (API), with details about its chemical form or salt, and a carrier.
- Claims 2-10: Detail variations including dosage forms, methods of administration, and specific excipients or stabilizers used.
- Claims 11-20: Describe methods of using the composition for treating the specified disease or condition.
- Claims 21-30: Cover manufacturing methods, stability enhancements, and controlled-release features.
The claim scope primarily involves the chemical entity, its formulations, and therapeutic methods. The claims are structured in a manner typical for drug patents, balancing composition coverage with method claims.
How Broad or Narrow Are the Claims?
Patent Scope
- Composition Claims: Generally broad to cover the API with common excipients.
- Method Claims: More specific, limiting to particular diseases or administration routes.
- Formulation Claims: Vary from broad (any formulation of the API) to narrow (specific excipient combinations or release mechanisms).
Limitations and Specificities
- The patent's claims limit themselves to certain forms of the API (e.g., salts, solvates) and specific formulations.
- The claims do not encompass all possible uses or derivatives, which indicates targeted patent protection rather than broad-spectrum coverage.
Patent Term
- The patent was filed around 2003, with a standard 20-year term, expected to expire in 2023 unless extended.
Patent Landscape: Similar Patents and Competitor Activity
Related Patent Families
- Several patents are linked to the core compound, covering:
- Alternative salts or polymorphs.
- Different formulations (e.g., controlled-release, combination therapies).
- Method of manufacture.
Competitor Patents
- Companies in similar therapeutic areas filed parallel patents, often expanding on their technology with broad claims.
- Some patent filings in the same class focus on formulations optimizing bioavailability or reducing side effects.
Patent Announcements & Litigation
- No public records indicate litigation directly involving this patent.
- Patent validity challenges are common for similar patents; however, this patent remains granted and enforceable until expiration.
Patent Filing and Priority
- Priority date: Likely around early 2003.
- Subsequent continuation or divisional filings may exist, expanding coverage or modifying claims.
- The landscape demonstrates active patenting around the same API or its cues in different jurisdictions, especially Europe and Japan.

FAQs
Q1: Can the patent be extended beyond its expiration date?
A: Patent term extensions are possible for patents associated with drug approval delays, but in the U.S., extensions are rare and limited to 5 years max.
Q2: How does this patent impact biosimilar development?
A: As this patent covers small molecules, biosimilar issues are less relevant; however, related formulations or methods might face patent hurdles.
Q3: Are there known patent challenges to this patent?
A: No publicized challenges or litigations are linked to patent 7,323,195.
Q4: What jurisdictional protections does this patent have?
A: Valid only in the U.S.; comparable patents may exist in other regions, which need separate review.
Q5: Can this patent cover combination therapies?
A: The claims focus on the specific composition and methods involving a single API; combination therapies would require additional patent coverage.
