Understanding the Scope and Claims of United States Patent 7,964,202
Introduction
United States Patent 7,964,202, titled "Method for treatment of common acne," is a patent that outlines a specific method and composition for treating acne. To delve into the scope and claims of this patent, it is essential to analyze its various components, including the background, summary, detailed description, and the claims themselves.
Background of the Patent
The patent US7964202B2 addresses the treatment of common acne, a widespread skin condition characterized by the occurrence of comedones (blackheads and whiteheads), papules, pustules, and sometimes cysts and nodules. The background section of the patent discusses the existing treatments for acne, including the use of benzoyl peroxide, retinoids, and other dermatological compositions. It highlights the need for more effective and less irritating treatments[4].
Summary of the Invention
The summary section provides an overview of the invention, which involves a method for treating acne using specific dermatological or cosmetic compositions. These compositions typically include a combination of active ingredients such as benzoyl peroxide and retinoids, along with other components like isopentadecane and 2-methyl-pentadecane. The method aims to prevent or treat cell differentiation, proliferation, and keratinization disorders associated with acne[4].
Detailed Description of the Invention
The detailed description section elaborates on the components and the method of the invention. It includes:
Active Ingredients
- Benzoyl Peroxide: Known for its antibacterial properties and its ability to reduce the blockage of pores.
- Retinoids: Derivatives of vitamin A that help in preventing the formation of comedones and reducing inflammation[4].
Other Components
- Isopentadecane: A natural product used to enhance the stability and efficacy of the composition.
- 2-Methyl-Pentadecane: Another component that contributes to the overall effectiveness of the treatment[4].
Method of Treatment
The method involves applying the composition to the affected skin area, typically once or twice a day. The composition can be in various forms such as gels, creams, or lotions, depending on the patient's skin type and the severity of the acne[4].
Claims of the Patent
The claims section is crucial as it defines the scope of the patent. Here are some key claims:
Independent Claims
- Claim 1: A method for treating acne, comprising applying a composition to the skin, where the composition includes benzoyl peroxide and a retinoid.
- Claim 5: The method of claim 1, where the composition further includes isopentadecane and 2-methyl-pentadecane[4].
Dependent Claims
- Claim 2: The method of claim 1, where the benzoyl peroxide is present in a concentration of about 2.5% to about 10%.
- Claim 3: The method of claim 1, where the retinoid is adapalene[4].
Patent Scope and Breadth
The scope of the patent is defined by the claims, which determine what is protected under the patent. In this case, the patent protects a specific method of treating acne using a combination of benzoyl peroxide and retinoids, along with other specified components.
Metrics for Measuring Patent Scope
Research on patent scope often uses metrics such as independent claim length and independent claim count. These metrics can indicate the breadth and clarity of the patent claims. For example, narrower claims at publication are associated with a higher probability of grant and a shorter examination process[3].
Prior Art and Citation Data
The patent cites prior art related to acne treatments, including compositions and methods involving benzoyl peroxide and retinoids. The Common Citation Document (CCD) application, which consolidates prior art cited by participating IP offices, would be useful in understanding the global citation landscape for this patent[1].
Legal Status and Expiration
The legal status of the patent indicates whether it is still in force or has expired. As of the current date, the patent US7964202B2 has expired, meaning that the protected method and composition are now in the public domain[4].
Practical Implications
The expiration of this patent allows other companies and researchers to use the described method and composition without infringing on the original patent. This can lead to more widespread availability of effective acne treatments and potentially lower costs for consumers.
Conclusion
United States Patent 7,964,202 provides a detailed method for treating common acne using a specific combination of active ingredients. Understanding the scope and claims of this patent is crucial for anyone looking to develop or use similar treatments. The expiration of the patent opens up opportunities for further innovation and accessibility in acne treatment.
