This patent is significant in the pharmaceutical industry, particularly in the development of unitary dosage forms. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.
Background and Inventors
The patent was invented by Terrence C. Dahl, Munir A. Hussain, and Robert L. Bell, among others, and assigned to Bristol-Myers Squibb & Gilead Sciences, LLC. The inventors aimed to create a unitary pharmaceutical dosage form that addresses specific challenges in drug delivery and formulation[1].
Scope of the Patent
The scope of the patent revolves around the development of a unitary pharmaceutical dosage form that combines multiple active pharmaceutical ingredients (APIs) into a single dosage unit. This dosage form is designed to improve the bioavailability, stability, and patient compliance of the APIs.
Key Components
- Active Pharmaceutical Ingredients (APIs): The patent describes formulations that include multiple APIs, which can be combined in various ratios to achieve desired therapeutic effects.
- Excipients and Formulation: The dosage form includes specific excipients and a detailed formulation process to ensure the stability and efficacy of the APIs.
- Delivery Mechanism: The patent outlines various delivery mechanisms, such as tablets, capsules, and other oral dosage forms, designed to release the APIs in a controlled manner[1].
Claims of the Patent
The patent includes several claims that define the scope of the invention:
Independent Claims
- Claim 1 describes a unitary pharmaceutical dosage form comprising at least two APIs, along with specific excipients and a detailed formulation process.
- Claim 2 specifies the ratios of the APIs and the types of excipients used.
- Claim 3 outlines the method of manufacturing the dosage form, including the steps involved in combining the APIs and excipients[1].
Dependent Claims
- These claims further detail the specific characteristics of the dosage form, such as the particle size of the APIs, the type of coating used, and the release profile of the APIs.
Patent Landscape
Prior Art and Related Patents
The patent landscape for unitary pharmaceutical dosage forms is extensive, with numerous prior patents and publications. For example, patents such as US 3,682,930 A and US 4,003,878 A describe earlier formulations and delivery mechanisms that laid the groundwork for the current invention[1].
Global Dossier and International Filings
