United States Patent 11,337,989: A Detailed Analysis of Scope, Claims, and Patent Landscape

Introduction

The United States Patent 11,337,989, titled "Compositions and methods for inhibiting inflammation and diseases using an alginic acid-based antimicrobial compound," is a significant patent in the field of pharmaceuticals and biomedical research. This patent, granted to its inventors, outlines innovative compositions and methods that utilize alginic acid to inhibit inflammation and reduce the risk of various diseases.

Patent Overview

Publication and Authority

The patent was published under the United States Patent and Trademark Office (USPTO) with the publication number US11337989B2. It is part of the patent application filed under US15/106,755 and was granted on October 4, 2022[4].

Prior Art and Background

The patent builds upon prior art related to alginic acid, a naturally occurring polymer found in brown seaweed. Alginic acid has been recognized for its various biomedical applications, including its antimicrobial and anti-inflammatory properties. The patent aims to leverage these properties to develop new compositions and methods for treating inflammation and diseases[4].

Claims and Scope

Independent and Dependent Claims

The patent includes a series of independent and dependent claims that define the scope of the invention. Independent claims typically outline the broadest aspects of the invention, while dependent claims narrow down the scope by adding specific details or limitations.

  • Independent Claims: These claims define the core compositions and methods involving alginic acid-based antimicrobial compounds. For example, Claim 1 might describe a composition comprising alginic acid and other components that inhibit inflammation and microbial growth[4].
  • Dependent Claims: These claims build upon the independent claims by specifying particular embodiments, such as the concentration of alginic acid, additional ingredients, or specific methods of application.

Claim Language and Metrics

The scope of the patent can be measured using metrics such as independent claim length and independent claim count. These metrics are important in assessing the breadth and clarity of the patent claims. For instance, longer independent claims may indicate a more detailed and specific invention, while a higher number of independent claims could suggest a broader scope of protection[3].

Compositions and Methods

Alginic Acid-Based Antimicrobial Compounds

The patent describes compositions that include alginic acid as the primary active ingredient. These compositions are designed to inhibit inflammation and reduce the risk of spreading diseases, including sexually transmitted diseases. The antimicrobial properties of alginic acid are harnessed to create formulations that can be applied topically or administered in other forms[4].

Additional Components

The compositions may also include other ingredients such as buffering agents (e.g., fumaric acid, ascorbic acid), microbiocidal agents, and stabilizers (e.g., EDTA). These components enhance the efficacy and stability of the alginic acid-based compounds[4].
