The patent pertains to a novel manufacturing process designed to enhance the efficacy, stability, or bioavailability of a specific pharmaceutical compound or composition.
Scope of the Patent:
1. Focus of the Invention
The patent claims a specific method or process in pharmaceutical manufacturing, possibly involving steps like precise mixing, temperature control, encapsulation, drying techniques, or the employment of particular excipients. The scope emphasizes innovation in process efficiency, production safety, or improvement in drug performance.
2. The Core Claim Categories
- Method Claims: Encompass specific steps, sequence, or conditions critical for producing a pharmaceutical composition.
- Product-by-Process Claims: Covering the resulting composition, characterized by the process used for its manufacturing.
- Use Claims: Possibly protecting the application of the process or composition for treating specific diseases.
3. Limitations and Boundaries
The patent limits its scope to processes involving unique parameters—such as temperature ranges, solvent systems, or processing times—and may exclude existing methodologies. The claims likely specify key features that distinguish it from prior art:
- Specific combination of process steps
- Use of novel excipients or carriers
- Unique process conditions (e.g., milling size, drying method)
- Targeted improvements like increased stability, bioavailability, or manufacturability
Claims Analysis
1. Main Claim (Independent Claim)
The main claim usually defines a particular manufacturing method characterized by a set of innovative steps or parameters:
- For eksempel, "A method comprising: (a) dissolving a pharmaceutical ingredient in a solvent under specific conditions; (b) drying the solution using a particular drying technique; (c) encapsulating the dried material in a biodegradable polymer."
2. Dependent Claims
Specify particular embodiments, such as:
- Specific solvents or excipients
- Precise process parameters (e.g., pH, temperature, pressure)
- Different formulations or dosage forms (tablets, capsules, powders)
- Additional steps like stabilization or coating
3. Patent Strategy Reflected in Claims
The broad independent claim ensures fundamental patent protection, while narrower dependent claims secure rights across specific embodiments or improvements. This layered approach curtails workarounds and extends the patent’s enforceability.
Patent Landscape and Competitive Positioning
1. Global Patent Family and Related Applications
The patent’s family likely includes applications filed across jurisdictions (EPO, USPTO, China, etc.), reflecting its strategic importance. The filing date and priority application, if any, influence the scope of prior art and potential for patent term extension.
