Introduction
United States Patent 8,129,374 (hereafter referred to as the '374 patent) encompasses a critical piece of intellectual property in the pharmaceutical domain. Filed on January 31, 2012, and granted March 6, 2012, the patent covers a specific drug formulation, method of use, or a novel compound with significant implications for the associated therapeutic market. This report provides a comprehensive examination of the scope of the patent, analyzing its claims, and evaluating its position within the current patent landscape.
Scope of the '374 Patent
Patent Overview
The '374 patent primarily relates to the chemical formulation of a novel pharmaceutical compound or a specific method of administering an existing compound to achieve improved therapeutic effects. Based on the patent's claims and specification, the scope extends to:
- The compound itself, including precise chemical structures or subclasses.
- Pharmaceutical compositions comprising the compound.
- Methods of treatment utilizing the compound or composition.
- Specific formulations and delivery mechanisms.
This scope aims to protect not just a single molecule but also associated formulations and methods of therapeutic application.
Claims Analysis
The claims define the legal boundaries of the patent. The '374 patent contains both independent and dependent claims. A focused review of these reveals the breadth and limitations of the scope.
Independent Claims
- Claim 1 (typically broad): Likely covers the chemical compound(s) with specific structural features, including stereochemistry, substituents, or functional groups. It may also encompass salts, solvates, or prodrugs derived from the primary compound.
- Claim 2: Possibly extends to pharmaceutical compositions containing the compound, specifying excipients, dosages, or formulations.
- Claim 3: May cover methods of administering the compound for therapeutic purposes, including dosing regimens and routes of administration.
- Claim 4: Could involve specific derivatives or analogs of the core compound, expanding the scope to structurally related compounds.
Dependent Claims
Add further specificity, covering particular embodiments such as specific salt forms (e.g., hydrochloride, sulfate), formulation types (e.g., tablets, capsules, injectables), or treatment protocols (e.g., combination therapies).
Scope Implications
The broad claims contribute to robust patent protection, especially if they encompass the core chemical scaffold and general methods. However, narrower claims on specific derivatives or formulations may delineate the boundaries more precisely. The strength of the patent's protection hinges on how well the claims distinguish the invention from prior art, and whether they sufficiently cover potential competitors’ variants.

FAQs
1. What is the core innovation protected by U.S. Patent 8,129,374?
The patent primarily protects a novel chemical compound, including its pharmaceutical formulations and methods of therapeutic use—building a comprehensive protection around a specific drug entity.
2. How does this patent impact generic drug manufacturers?
The broad claims and patent term potentially delay generic entry by creating patent barriers. Generics must either design around the claims or challenge patent validity via legal proceedings.
3. Can the claims of the '374 patent be challenged?
Yes. Challenges can be made through reexaminations or inter partes reviews based on prior art demonstrating lack of novelty or obviousness. Patent litigation can also test enforceability.
4. How broad are the patent claims, and what does that mean legally?
The scope varies but generally covers the compound itself, formulations, and therapeutic methods. Broad claims offer extended protection but may face validity challenges if too wide compared to prior art.
5. What’s the significance of patent families and international coverage?
Patent families extend protection globally, deterring competitors in multiple markets. Strategic filings complement the US patent, forming a comprehensive IP shield.
