Introduction
Understanding the scope and claims of a patent is crucial for inventors, researchers, and businesses to navigate the complex landscape of intellectual property. This article will delve into the details of United States Patent 5,514,650, titled "Aza cyclohexapeptide compounds," and provide a thorough analysis of its scope, claims, and the broader patent landscape.
Background of the Patent
United States Patent 5,514,650 was granted for "Aza cyclohexapeptide compounds," which are a class of synthetic peptides with potential therapeutic applications. The patent describes the synthesis, structure, and properties of these compounds, as well as their potential uses.
Patent Claims
Independent Claims
The patent includes several independent claims that define the scope of the invention. These claims are critical as they outline what is considered novel and non-obvious about the invention.
- Claim 1: This claim typically defines the broadest scope of the invention, often describing the general structure of the aza cyclohexapeptide compounds.
- Claim 2-5: These claims may narrow down the scope by specifying particular aspects of the compounds, such as specific amino acid sequences, synthesis methods, or pharmacological properties.
Dependent Claims
Dependent claims build upon the independent claims, providing additional details or limitations that further define the invention.
- Claim 6-10: These might include specific examples of the compounds, their uses in therapeutic applications, or methods for their preparation.
Claim Analysis
To understand the patent's scope, it is essential to analyze each claim carefully. For instance, if Claim 1 describes a broad class of aza cyclohexapeptide compounds, dependent claims might specify particular compounds within that class that have been found to have unique properties or uses.
Patent Scope

Patent Landscape
Prior Art
Understanding the prior art is essential to determine the novelty and non-obviousness of the invention. Prior art includes all publicly available information that existed before the patent application was filed.
- Search Tools: Utilizing tools like the USPTO's Patent Public Search, Global Dossier, and international patent databases can help identify relevant prior art[1].
Related Patents
Analyzing related patents can provide insights into the broader patent landscape and potential overlaps or distinctions.
- Patent Families: Using the Global Dossier service, one can identify related applications filed at participating IP Offices, which helps in understanding the global scope of similar inventions[1].
Litigation and Disputes
Patents can be involved in litigation, especially when there are disputes over infringement or validity.
- Example: While not directly related to this patent, disputes over pharmaceutical patents, such as the one between Merck and Sandoz over Cancidas, highlight the importance of clear claims and scope definitions[5].
International Patent Considerations
Global Patent System
The global patent system is harmonized through initiatives like the Common Citation Document (CCD) and Global Dossier.
- CCD: This tool consolidates prior art cited by multiple offices, making it easier to visualize the global patent landscape for a particular invention[1].
International Search Resources
Searching international patent databases is crucial to ensure that the invention is novel and non-obvious globally.
- EPO, JPO, WIPO: Databases provided by these offices offer access to international patent applications and machine translations, which can be invaluable in conducting a comprehensive search[1].
Economic and Research Implications
Patent Claims Research Dataset
The USPTO's Patent Claims Research Dataset provides detailed information on claims from US patents, which can be used to analyze trends and scope measurements.
