Understanding the Scope and Claims of United States Patent 6,451,991
Introduction
United States Patent 6,451,991 is one of the patents issued to Ionis Pharmaceuticals, Inc., a company known for its innovative work in the field of antisense therapeutics. This patent, along with several others, highlights the company's extensive research and development in gene-targeted therapies.
Background on Ionis Pharmaceuticals
Ionis Pharmaceuticals, Inc. has been a pioneer in the development of antisense oligonucleotides, which are short, single-stranded nucleic acid molecules designed to bind to the messenger RNA (mRNA) of a target gene. This binding can either block the production of a specific protein or modify the mRNA to produce a different protein. The company's 1,000th patent milestone, which includes U.S. Patent 6,451,991, underscores its significant contributions to the field of genetic medicine[2].
Patent Overview
Patent Number and Title
U.S. Patent 6,451,991 is titled "Chemistry Patents" and is part of a series of patents issued to Ionis Pharmaceuticals, Inc. This particular patent falls under the category of chemistry patents, which are distinct from the gene-related patents also issued to the company.
Claims and Scope
The patent claims in U.S. Patent 6,451,991 are related to specific chemical compounds and their synthesis methods. Here are some key aspects of the claims:
- Chemical Compounds: The patent describes and claims novel chemical compounds, particularly those related to antisense oligonucleotides. These compounds are designed to target specific genes and modify their expression.

- Independent Claims: These define the broadest scope of the invention and are usually the most critical claims.
- Dependent Claims: These narrow down the scope by adding additional limitations to the independent claims.
Claim Examples
While the exact text of the claims is not provided here, an example of a claim might look like this:
"A method of synthesizing an antisense oligonucleotide comprising the steps of:
- Preparing a nucleoside precursor;
- Coupling the nucleoside precursor to a solid support;
- Iteratively adding nucleoside precursors to form an oligonucleotide chain;
- Cleaving the oligonucleotide from the solid support;
- Purifying the oligonucleotide."
This is a hypothetical example, but it illustrates the level of detail and specificity involved in patent claims.
