Patent Overview

Publication Details

  • Publication Number: US8741881B2
  • Authority: United States
  • Prior Art Date: The patent was filed on December 21, 2012, and granted on June 3, 2014[4].

Invention Description

The patent describes an improved transdermal hydroalcoholic testosterone gel formulation. This formulation is designed to provide a desirable balance of testosterone delivery and stability, making it more effective and user-friendly for patients[4].

Claims Analysis

Claim Structure

The patent includes multiple claims, each defining a specific aspect of the invention. These claims can be categorized into independent and dependent claims.

  • Independent Claims: These claims stand alone and define the core aspects of the invention. For example, Claim 1 might describe the composition of the testosterone gel, while Claim 2 might describe the method of applying the gel.
  • Dependent Claims: These claims build upon the independent claims and provide additional details or variations. For instance, a dependent claim might specify the concentration of testosterone in the gel or the type of solvent used[4].

Claim Construction

Claim construction is a critical process in patent law, as it determines the scope of the patentee's rights. The court considers the literal language of the claim, the patent specification, and the prosecution history when construing patent claims. This process ensures that the claims are interpreted in a way that aligns with the inventor's intent and the broader context of the patent[2].

Scope of the Patent

Patent Scope Measurements

The scope of a patent is a measure of its breadth and coverage. For US Patent 8,741,881, the scope can be analyzed using various metrics, such as the number of claims, the dependency between claims, and the specificity of the claim language. The USPTO's Patent Claims Research Dataset provides tools to analyze such metrics, helping to understand the patent's scope and its position within the broader patent landscape[3].

Patent Family and Related Applications
