Detailed Analysis of the Scope and Claims of United States Patent 5,466,861: A Comprehensive Guide

Introduction

United States Patent 5,466,861, titled "Bridged Bicyclic Aromatic Compounds and Their Use in Modulating Gene Expression of Retinoid Receptors," is a significant patent in the field of pharmaceuticals and biotechnology. This patent, issued to researchers involved in the development of novel compounds, provides a detailed insight into the invention, its claims, and the broader patent landscape.

Patent Overview

Publication Details

  • Publication Number: US5466861A
  • Authority: United States
  • Prior Art Date: The patent was granted based on prior art dating back to the early 1990s[4].

Invention Description

The patent describes novel bridged bicyclic aromatic compounds and their use in modulating gene expression, particularly in the context of retinoid receptors. These compounds are designed to regulate cellular processes influenced by thyroid hormone, vitamin D, and retinoids such as 9-cis-retinoic acid. The invention includes pharmaceutical compositions containing these compounds and methods for their use in treating various conditions, including bone calcification and energy regulation[4].

Claim Scope

Importance of Claim Scope

The claim scope in a patent application is crucial for defining the boundaries of the invention and ensuring the patent's validity. A common misconception is that broader claims are always better, but this can lead to difficulties in getting the patent granted and increased risk of invalidation[3].

Specific Claims in US5466861A

The claims in this patent are detailed and specific, focusing on the structural formulas of the bridged bicyclic aromatic compounds. For example:

  • The compounds have a specific structural formula (I) with defined groups such as R1, R2, and R3.
  • R1 can be selected from lower alkyl or adamantyl groups.
  • R2 can be --O--R13 or --S--R13 where R13 is lower alkyl.
  • The compounds can form 5- or 6-membered cycloalkylene rings with specific substitutions[4].

Balancing Claim Scope

The claims must be balanced to ensure they are not overly broad, which could lead to invalidation due to abstract idea exceptions or failure to meet the written description requirement. The patent drafters have carefully defined the claims to be anchored to the embodiments disclosed in the specification, avoiding the pitfalls of overly broad claims[3].

Patent Landscape Analysis

Defining Scope and Keywords

To analyze the patent landscape around US5466861A, one must define the scope of the analysis and identify relevant keywords. This includes terms related to bridged bicyclic aromatic compounds, retinoid receptors, and gene expression modulation[5].

Searching and Organizing Patents
