United States Patent 6,103,248: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
United States Patent 6,103,248, titled "Topical preparation and therapy for head lice," was awarded to Craig G. Burkhart and his associates on August 15, 2000. This patent addresses a persistent and widespread problem of head lice infestation, particularly among children.
Background and Problem Statement
Head lice infestation is a significant public health issue, affecting millions of people annually. According to reports, approximately six million U.S. school children and ten million people of all ages are infested with head lice each year[1].
Patent Overview
The patent describes a topical preparation and therapy designed to treat head lice effectively. Here is a breakdown of the key components:
Topical Preparation
The topical preparation includes a killing agent, a carrier, and optionally, a surfactant. The killing agent is crucial for eliminating the lice and their nits (eggs), while the carrier ensures the even distribution of the active ingredients on the scalp. The surfactant, if included, enhances the penetration and spread of the preparation[1].
Therapy Method
The therapy involves applying the topical preparation to the scalp, typically leaving it on for a specified period before rinsing. This method is designed to be safe, effective, and easy to administer, making it suitable for both children and adults[1].
Claims and Scope
The patent includes 20 claims that define the scope of the invention. Here are some key aspects:
Independent Claims
- The patent claims cover the composition of the topical preparation, including the killing agent, carrier, and surfactant.
- It also claims the method of treatment, which involves applying the preparation to the scalp and rinsing it off after a specified time[1].
Dependent Claims
- These claims further specify the types of killing agents, carriers, and surfactants that can be used.
- They also detail the concentration ranges of these components and the conditions under which the treatment should be applied[1].
Patent Scope Metrics
To understand the scope of this patent, metrics such as independent claim length (ICL) and independent claim count (ICC) can be used. These metrics help in assessing the breadth and clarity of the patent claims.
- Independent Claim Length (ICL): This metric measures the number of words in the shortest independent claim. A shorter ICL generally indicates narrower and more specific claims.
- Independent Claim Count (ICC): This metric counts the total number of independent claims. Fewer independent claims often suggest a more focused invention[3].
