United States Patent 9,427,402, titled "Preparation for improving solubility of poorly soluble drug," addresses a significant challenge in pharmaceuticals: enhancing the solubility of drugs that are difficult to dissolve. The patent describes a method and composition for improving the solubility of such drugs, which is vital for their effective absorption and therapeutic efficacy.
Inventors and Assignees
The patent was granted to inventors who have developed this innovative solution, and it is assigned to a specific entity, typically a pharmaceutical company or research institution. Understanding the assignee can provide insights into the commercial and research interests behind the patent.
Scope of the Patent
Technical Field
The patent falls within the technical field of pharmaceutical formulations, specifically focusing on solubility enhancement techniques. This field is critical for drug development, as many drugs are inherently poorly soluble, which can limit their bioavailability and therapeutic effectiveness.
Detailed Description
The patent provides a detailed description of the preparation method, including the materials and processes involved. This includes the use of specific excipients, solvents, and formulation techniques that enhance the solubility of the drug. The description also covers the advantages of the invention, such as improved bioavailability and stability of the drug formulation.
Claims of the Patent
Independent and Dependent Claims
The patent includes both independent and dependent claims. Independent claims define the broadest scope of the invention, while dependent claims narrow down the scope by adding additional limitations. For example, an independent claim might describe the general method of preparing a solubility-enhanced drug formulation, while a dependent claim might specify a particular excipient or solvent used in the process.
Claim Analysis
Analyzing the claims involves understanding the specific elements and limitations defined in each claim. This is crucial for determining the patent's scope and potential infringement. Here is an example of how to analyze a claim:
- Independent Claim 1: A method for improving the solubility of a poorly soluble drug, comprising mixing the drug with a specific excipient and solvent.
- Dependent Claim 2: The method of claim 1, wherein the excipient is a polymer and the solvent is an aqueous solution.
Claim Scope and Limitations
The scope of the claims defines what is protected by the patent. Any method or product that falls within the scope of these claims could be considered an infringement. The limitations in the claims, such as specific materials or processes, help to narrow down the scope and avoid overly broad protection.
Patent Landscape
Prior Art and Related Patents
To understand the patent landscape, it is essential to identify prior art and related patents. This involves searching databases such as the USPTO's Patent Public Search, the European Patent Office's esp@cenet, and other international patent databases[1][4].
Global Dossier and International Filings
The Global Dossier service provided by the USPTO allows users to view the patent family for a specific application, including related applications filed at participating IP Offices. This helps in understanding the global reach and protection of the patent[1].
Citation Data and Office Actions
