Patent Overview
Patent Number and Status
The patent number is US8075911B2, and it was granted after a thorough examination process. The patent has since expired due to fee-related issues[1].
Inventors and Assignees
While the specific inventors and assignees are not detailed in the provided sources, the patent is a result of extensive research and development aimed at improving transdermal nicotine delivery.
Prior Art and Related Patents
The patent builds upon a wide range of prior art, including various U.S. patents that describe different aspects of transdermal drug delivery systems. These include patents related to the design of the backing layer, the adhesive properties, and the overall structure of the device[1].
Key Claims and Innovations
Transparency and Opacity Index
One of the primary innovations of this patent is the development of a transparent transdermal nicotine delivery device with an Opacity Index of less than 48.6%. This transparency is a significant improvement over earlier designs, which were often opaque and less aesthetically pleasing[1].
Backing Layer
The patent describes the use of a transparent polymeric material as the backing layer. This material is crucial for maintaining the transparency of the device while ensuring its structural integrity[4].
Adhesive and Drug Delivery Mechanism
The device includes an adhesive layer that facilitates the delivery of nicotine through the skin. The design ensures a controlled release of the drug, providing a consistent therapeutic effect[1].
Patent Application and Examination Process
Application History
The patent application (U.S. Appl. No. 11/841,789) underwent several stages of review, including preliminary amendments, office actions, and responses to these actions. The process involved multiple interactions with the USPTO, including interviews and appeals, before the patent was finally granted[4].
Office Actions and Responses
The application faced several office actions, each requiring a detailed response from the applicants. These interactions were crucial in refining the claims and ensuring that the patent met the necessary standards for grant[4].
Legal and Regulatory Context
USPTO Role
The U.S. Patent and Trademark Office (USPTO) played a central role in the granting of this patent. The USPTO is responsible for evaluating patent applications and ensuring that they meet the criteria for patentability[2].
Patent Scope and Claims Research
The USPTO also maintains datasets and research tools, such as the Patent Claims Research Dataset, which provide detailed information on claims from U.S. patents. These resources can be used to analyze the scope and claims of patents like US8075911B2[3].
Impact on the Market
Aesthetic and Functional Improvements
The transparency of the device makes it more aesthetically appealing, which can enhance user compliance. Additionally, the improved design ensures better functionality and ease of use, making it a preferred option for nicotine replacement therapy[1].
Competitive Landscape
The innovation represented by this patent can influence the competitive landscape in the transdermal drug delivery market. Companies that adopt similar transparent designs may gain a market advantage due to the enhanced user experience and aesthetic appeal[1].
Future Developments and Trends
Small Claims Patent Court
While not directly related to this specific patent, the concept of a small claims patent court, as studied by the Administrative Conference of the United States (ACUS), could impact future patent disputes and the overall patent landscape. This court could provide a more efficient and cost-effective way to resolve patent-related issues[5].
Advances in Transdermal Technology
The field of transdermal drug delivery is continuously evolving, with new materials and technologies being developed. Future patents in this area may build upon the innovations presented in US8075911B2, further enhancing the efficacy and user experience of transdermal devices[1].
