SO-TI XLUS was a patent data analysis software created by the Japanese IP knowledge analysis company SO-TI, Inc. XLUS provided four different ASP services:
- XLUS Green - Handles Japanese published patent applications.
- XLUS White - Handles Japanese published patent applications.
- XLUS Eagle G - Handles US patents.
- XLUS Eagle W - Handles US patents.
As of November 2012, this tool no longer appears to be available.
Users must purchase a license to receive access to the SO-TI online patent database.
Within XLUS, users can search by either patent number or text. The text search allows for natural language searching, including pasting text directly from articles or website descriptions into the search form. According to the SO-TI website, "one hundred relevant patents will be retrieved immediately" for each search.
The visualization produced by XLUS is a "radar chart," which illustrates technological similarities among patent documents. Each patent document is displayed as a dot located on a radar screen surrounded by other patent document dots. Closer dots are more technologically similar. The original search criteria is in the center of the chart, as the main technology indicator. According to a description of the product at Assay Depot:
Patents with similar content are arranged in positions around the original, with their distance from the center indicating their similarity to the original, and the angle at which they are displayed also indicates the nature of the content (that is, patents with content similar to each other will be displayed at the same “o’clock” relative to the original).
A list of assignees beside the chart allows the user to select assignee names to highlight the assignee's patent holdings on the radar chart. Each assignee name produces a different highlighting color. The dot sizes may also be used to represent the number of patents within a cluster of similar patents.
