Understanding the Scope and Claims of United States Patent 8,435,502
Introduction
United States Patent 8,435,502, titled "Cosmetic/dermatological compositions comprising naphtholic acid compounds and polyurethane polymers," is a patent that covers specific formulations and methods for treating dermatological conditions. Here, we will delve into the details of the patent's scope, claims, and the broader patent landscape in which it resides.
Patent Overview
The patent, assigned to a company involved in cosmetic and dermatological research, describes compositions and methods for the treatment of skin conditions such as acne. These compositions include naphtholic acid compounds and polyurethane polymers, which are formulated for topical application[2].
Claims
The patent includes several claims that define the scope of the invention. Here are some key claims:
Independent Claims
- Claim 1 typically describes the broadest aspect of the invention, which in this case might include the composition comprising naphtholic acid compounds and polyurethane polymers.
- Claim 2 and subsequent claims may narrow down the invention by specifying particular concentrations of the compounds, methods of application, or specific dermatological conditions treated.
Dependent Claims
- These claims build upon the independent claims, adding additional limitations or specifications. For example, a dependent claim might specify a particular ratio of naphtholic acid to polyurethane polymer or a specific method of preparation.
Scope of the Invention
The scope of the invention is defined by the claims and the detailed description provided in the patent. Here are some key aspects:
Active Ingredients
- The patent focuses on the use of naphtholic acid compounds, which are known for their dermatological benefits, particularly in treating acne.
- Polyurethane polymers are included to enhance the stability and delivery of the active ingredients.
Formulation
- The compositions are formulated for topical application, indicating that they are designed to be applied directly to the skin.
- The patent may specify various forms of the composition, such as creams, gels, or ointments.
Methods of Treatment
- The patent describes methods for treating dermatological conditions, including acne, using the specified compositions.
Patent Landscape Analysis
Saturated Patent Space
The field of dermatological and cosmetic compositions is highly saturated with patents. Conducting a patent landscape analysis is crucial to understand the competitive landscape and potential barriers to entry. This analysis helps in identifying existing patents, pending applications, and the overall saturation level in the technology area[3].
Competitors and Related Patents
- A comprehensive patent landscape analysis would reveal other patents and applications related to dermatological treatments, including those from competitors.
- This analysis can help in identifying gaps in the current technology and potential areas for innovation.
Global Patent System
- The patent landscape extends beyond the U.S., involving international patent offices. Tools like the Global Dossier and Common Citation Document (CCD) can provide insights into related applications and citations across different jurisdictions[4].
Allowance Rates and Patent Prosecution
The probability of receiving a U.S. patent, as studied by Carley, Hegde, and Marco, indicates that only about 55.8% of patent applications are eventually granted without using continuation procedures. This rate varies significantly across different technology fields, with "Drugs and Medical Instruments" and "Computers and Communications" fields showing a decrease in allowance rates over time[1].
Implications for Inventors and Policymakers
- For inventors, understanding the patent landscape and the specific claims of existing patents like US 8,435,502 is crucial for avoiding infringement and identifying novel aspects of their inventions.
- Policymakers can use data from patent landscape analyses to inform policies related to intellectual property, innovation, and competition in the pharmaceutical and cosmetic industries.
Tools for Patent Searching
Several tools are available for conducting thorough patent searches, including the USPTO's Patent Public Search, Global Dossier, and resources from international intellectual property offices. These tools help in identifying prior art, tracking the status of related applications, and analyzing the patent family of a specific application[4].
Conclusion
Understanding the scope and claims of United States Patent 8,435,502 requires a detailed analysis of the patent document itself, as well as a broader examination of the patent landscape. This involves identifying key claims, understanding the formulation and methods described, and analyzing the competitive and regulatory environment in which the patent exists.
