Patent Search - XLUS EagleG

Service Description

Provider: SO-TI, Inc., was founded in 2006 in Tokyo, Japan. SO-TI has developed a web-based patent search platform that provides a radar-type visualization of relevant parts of the US or Japan Patent Office databases, using natural language queries to discover and display the relationship of patents to each other. SO-TI makes it possible to rapidly gain insight on the technological environment and future trend as well as the strengths and weaknesses of any company’s IP portfolio.

Background: It takes much effort and time to conduct a patent landscape search and a state-of-the-art search, which are important for determining the direction of research activities. Most of the time is spent reading the retrieved documents to categorize them. Such human-based categorization tends to be subjective, and the output varies depending on the skill of the individual. In contrast, XLUS EagleG electronically categorizes thousands of patents into clusters and places clusters that are similar to each other in the same area. Thus, an objective output can be obtained very quickly.

Service Details: An interface screen of XLUS EagleG is shown below. Any idea may be input into the query box in the form of natural language sentences. Alternatively, a user may copy and paste text data from other sources including academic papers and websites of other companies. The one hundred most relevant patents will be retrieved immediately. XLUS does not necessarily require a user to prepare a search formula. Therefore, even without much knowledge of the technology to be searched, retrievals and screening analyses can be conducted.

In order to search for relevant patents, XLUS utilizes a scheme called “tf-idf.” Using this scheme, the similarity between documents is calculated. The recent introduction of parallel computing technology has enabled XLUS to perform tremendous quantities of calculations within a few seconds. More than forty million words including compound terms appearing in all United States Patents are utilized in the retrieval. The accuracy of the search is ensured even if the number of patents to be retrieved continues to increase.

One of the core technologies of SO-TI resides is the original way in which search results are presented. In order to illustrate the similarity and technological relationships among patents, XLUS produces a radar chart. The distances between dots indicate the degree of similarity. After the query is submitted, SO-TI’s server farm performs the search and analysis, and within a few seconds the searcher’s Web browser shows relationships as a radar chart, with the original search term in the center.

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). As well as these angular and radial dimensions, the map provides two other visual metrics. The first is color — the names of the holders of the mapped patents are given to the right of the map, and clicking on these names highlights the holders’ patents on the map, with a different color assigned to each holder. Lastly, the size of the markers on the map can indicate “patent clusters” of very similar patents. The radar charts of XLUS allow a user to obtain a panoramic view of retrieved patents and provide extensive information that is intuitively understandable.





Deliverable: After selecting a license term in the Service Order Form and placing the order, you will receive an email from SO-TI within one day that includes an accession code to conduct patent searches on SO-TI’s web-based patent database.

Price: The default price for this service ($500) is for a one month licene. You can purchase a license for between one and 12 months by selecting the appropriate service in the Service Order Form. You also have an option for a free trial for one (1) week. After submitting your order, you will receive an access code from SO-TI by email. You can then visit http://so-ti.com/en, enter your access code, and begin searching US patents.
