Patent Overview
United States Patent 8,778,916, titled "Oral Pharmaceutical Composition," was granted to address specific needs in the pharmaceutical industry. Here is a brief overview of the patent:
Invention Description
The patent describes an oral pharmaceutical composition, particularly focusing on the formulation of testosterone undecanoate. The composition is designed to improve the bioavailability and stability of testosterone undecanoate when administered orally[5].
Claims Analysis
The claims section of a patent is critical as it defines the scope of the invention and what is protected by the patent.
Independent Claims
- Claim 1: This is the broadest claim and sets the foundation for the invention. It describes an oral pharmaceutical composition comprising 18-22 percent by weight of solubilized testosterone undecanoate and 50-55 percent by weight of a solubilizing agent[5].
Dependent Claims
- These claims further specify the components and their proportions, such as the type of solubilizing agents, other ingredients, and the formulation process. For example, dependent claims might specify the use of particular solubilizing agents like castor oil or medium-chain triglycerides.
Scope of the Patent
The scope of the patent is determined by the claims and the description provided in the specification.
Key Components
- Testosterone Undecanoate: The patent focuses on the solubilization of testosterone undecanoate, which is a critical component for the oral delivery of testosterone.
