Overview of United States Patent 7,632,517
Patent Title and Abstract
United States Patent 7,632,517, titled "Buccal, polar and non-polar spray containing zolpidem," pertains to the development of buccal aerosol sprays or capsules that facilitate the rapid absorption of zolpidem through the oral mucosa. Zolpidem is a medication commonly used for the short-term treatment of insomnia.
Inventors and Assignees
The patent was granted to inventors who developed this innovative formulation, and it is assigned to a pharmaceutical company. Understanding the assignee is important for determining the current ownership and potential licensing or collaboration opportunities.
Claims Analysis
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.
- Independent Claims: These claims outline the core elements of the invention, such as the composition of the buccal spray, the type of solvents used (polar and non-polar), and the method of administration.
- Dependent Claims: These claims build upon the independent claims by specifying additional features, such as the concentration of zolpidem, the type of excipients used, and any specific manufacturing processes.
Claim Construction
Claim construction is the process of interpreting the meaning and scope of the claims. This is critical for determining what is protected by the patent and what might infringe upon it. The claims in this patent would be analyzed to understand the exact formulation, the method of delivery, and any other specific aspects that are protected.
Scope of the Patent
Protected Subject Matter
The scope of the patent defines what is protected and what is not. For Patent 7,632,517, the protected subject matter includes:
- The specific formulation of the buccal spray containing zolpidem.
- The use of polar and non-polar solvents.
- The method of administration through the oral mucosa.
Exclusions and Limitations
Understanding what is not protected is equally important. For example, the patent might not cover other routes of administration or different formulations that do not use the specified solvents.
Patent Landscape
Prior Art and Related Patents
To understand the patent landscape, it is essential to conduct a thorough search of prior art and related patents. Tools like the USPTO's Patent Public Search, Global Dossier, and international databases such as the European Patent Office's esp@cenet and WIPO's PATENTSCOPE can be used to identify similar patents and applications[1][4].
Competitive Analysis
Analyzing the competitive landscape involves identifying other patents and products in the same field. This can include looking at patents held by competitors, new applications in the pipeline, and any ongoing litigation related to similar inventions.
International Patent Protection
Global Patent Family
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 can help in understanding the global protection of the invention[1].
Machine Translation and International Databases
