Introduction
United States Patent 5,591,454, titled "Method for administering glipizide," is a patent that covers a specific method for the administration of the antidiabetic drug glipizide. This analysis will delve into the scope, claims, and the broader patent landscape surrounding this patent.
Background of the Patent
The patent, granted to an undisclosed assignee, focuses on a method for administering glipizide, a well-known antidiabetic medication. Glipizide is used to treat type 2 diabetes by stimulating the release of insulin from the pancreas.
Scope of the Patent
The scope of the patent is defined by its claims, which outline the specific method of administering glipizide. Here are the key aspects:
Claims Overview
- The patent includes claims that describe the method of administering glipizide to a patient in need of antidiabetic treatment.
- The claims specify the dosage, timing, and possibly the formulation of glipizide to achieve optimal therapeutic effects[2].
Method of Administration
- The method involves administering glipizide in a way that enhances its bioavailability or efficacy.
- This could include specific dosing regimens, formulations (e.g., tablets, capsules), or delivery mechanisms designed to improve the drug's performance.
Claims Analysis
Independent Claims
- Independent claims are those that stand alone and do not depend on other claims. These claims typically define the broadest scope of the invention.
- For example, Claim 1 might describe the general method of administering glipizide, while subsequent claims might narrow down to specific aspects such as dosage or formulation.
Dependent Claims
- Dependent claims build upon the independent claims and provide additional details or limitations.
- These claims help to further define the invention and can be used to distinguish the patented method from prior art.
