Understanding Patents and Their Components
Before diving into the specifics of US Patent 5,047,398, it is essential to understand the basic components of a patent.
What is a Patent?
A patent is a form of intellectual property that grants the owner exclusive rights to make, use, sell, and distribute an invention for a specified period, usually 20 years from the filing date[4].
Patent Claims
Patent claims are the heart of a patent, defining the scope of protection granted by the patent. They outline what the inventor considers to be their invention and what they seek to protect[3].
Locating and Accessing Patent Information
To analyze US Patent 5,047,398, you need to locate and access the patent documentation.
Using the USPTO Patent Public Search
The USPTO's Patent Public Search tool is a powerful resource for finding and analyzing patents. This tool replaced legacy search tools like PubEast and PubWest, offering enhanced access to prior art and modern interfaces[1].
Patent 5,047,398: Overview
Patent Title and Abstract
To begin, identify the title and abstract of the patent. This provides a high-level overview of the invention.
Claims Analysis
The claims section is where the inventor specifies what is considered the invention. Here, you will find detailed descriptions of the invention's components, their relationships, and any limitations.
Independent and Dependent Claims
- Independent Claims: These claims stand alone and define the invention without reference to other claims.

Claim Scope
The scope of the claims determines the breadth of protection. Broader claims may cover more variations of the invention, while narrower claims are more specific but offer less protection.
Analyzing the Patent Landscape
Prior Art and Citations
Understanding the prior art cited in the patent is crucial. The Common Citation Document (CCD) application can help consolidate citation data from multiple offices, providing a comprehensive view of prior art[1].
Global Dossier
The Global Dossier service allows users to view the patent family for a specific application, including related applications filed at participating IP offices. This helps in understanding how the patent fits into the global patent landscape[1].
Legal and Policy Considerations
Enablement and Written Description
The USPTO guidelines for assessing enablement and written description are critical in determining the validity of the patent claims. These guidelines ensure that the patent specification provides sufficient information for one skilled in the art to make and use the invention[5].
Economic and Research Implications
Patent Claims Research Dataset
The USPTO's Patent Claims Research Dataset provides detailed information on claims from US patents and applications. This dataset can be used to analyze trends and measurements of patent scope, offering insights into the economic impact of patents[3].
Practical Steps for Conducting a Preliminary Search
To ensure that your analysis is thorough, follow these steps:
Step-by-Step Strategy
