The Keyword Analyzer tool counts the term frequency of specific terms found in a single patent. It is found in the "Keywords" tab on the document details window. Depending on how wide you set your DD window, you may have to scroll to the right a bit to expose the Keywords tab.

The Keyword Analyzer uses a straight term and string count method. It breaks up the terms counted in the document into two sets, the Claims Only and the Full Text.

The Keyword Analyzer uses stop-terms to remove common words like articles and prepositions, as well as common "patentese" terms like method, apparatus, claim, invention etc.

The Keyword Analyzer has a tool for creating new queries from the terms found in the patent of interest.

In this article, we'll review some of the basic ideas behind keyword searching.  

Patent documents are full of words.  Patents themselves can be relatively short, such as a two page design patent, while other patents can contain over 1000 pages of text!

Keywords are mainly found in four fields: Title, abstract, claims, and specification (which is also called the description or the disclosure).  When keyword searching, you'll want to keep in mind where in the document you want to search for certain terms, and how the language might vary in different parts of the document.

A keyword can be either a single term, like "fingerprint," "security," or "financial."  A keyword can also be a string such as "light emitting diode," "wireless communication" or "target molecule."

Too often patent searchers rely too heavily on keyword searching.  Keyword searching is amazingly powerful, but it should be used in conjunction with classification, and date searching for optimal results.

The Advanced Search window provides many tools for search patent data.

The search result grid is set up very much like a spreadsheet with familiar options for sorting and re-ordering. The spreadsheet-like view is helpful to quickly assess your search results.

However for doing a semi-detailed level-one analysis of each patent, it is helpful to view more information than what is available in the standard view–specifically the abstract and the representative patent image.
