BasicsLogin & Analysis Types
Understand the Radar
Patents in the data set are text mined and grouped together in clusters based on semantic similarities, or individual plots are created if an unclustered analysis is selected. Then they are run through multi-dimensional scaling and precisely positioned on a 2D radar based on their differences. Each dot represents one cluster or plot, with the size of the cluster reflecting the number of patents it contains. The closer the clusters the more similar their contents are. The XY axes have no particular meaning: distance is the focus of the data landscape.
Contour lines are created based on document density in areas of the radar, indicating possible semantic similarities or other levels of connectivity.
The analysis is automatically based on the company or organization that has the most patents in the data set: the Target Company. The others on the target list are the ones with the closest centers of gravity (overall document similarity) and filing ranges to the target company.

Create a Data Set to Analyze
Name: enter the name you'd like to give the data set.
Search type: select Text (concept search) or Patent Number.
Search query: enter up to 520K characters in the query box for a concept search, or enter patent numbers for the basis of the analysis. For best accuracy with text searches, the more words the better. If less than 5 are entered, any document containing any of the words can be included in the results (creating noise). Note that the tool mainly extracts and utilizes nouns, verbs, and adjectives for the analysis.
noteFor WIPO and EPO patent searches, the type of document must be included in the number, e.g. WO1991011363A1
If patent numbers are entered in the query box, the text in the patent(s) will be mined and similar documents will be included in the results. To analyze a list of specific patents only, use the Upload Patent List File function (see below)
- Part of Document to Search:
- Full Text searches the entire document.
- Abstract and Claims searches just that part of the document.
- Full Text with emphasis on Abstract and Claims searches the entire document and puts extra weight (priority) on the Abstract and Claims.
- Number of patents: enter the maximum number of patents you'd like to include in the data set, up to 100K.
- Filter by Bibliographic Data:
- NOTE: Using quotation marks when filtering helps reduce noise in the data set, e.g. "fuel cell" or "Apple, Inc". You can also use search operators AND, OR, (-) negation, ( ), and "string literal".
- Title: use to search by words in a patent title.
- Applicant: applicant/assignee refers to the company or organization name, e.g. Hitachi or Harvard University.
- Latest Assignee: refers to the most recent owner of a patent. Only available on US-A, US-R, JP-A, and JP-R.
- Inventor: full names must be input with last name, then a comma, then first name. e.g. EDISON, Thomas.
- IPC: single IPCs must be entered as, e.g., B64C. If adding IPC classification group/subgroup, it must be in quotation marks with spacing between the code and number. Use two spaces if the group/subgroup has 4 digits, e.g., “B64C␣␣15/12”, and three spaces if the group/subgroup has 3 numbers, e.g. "B64C␣␣␣9/00". If doing multiple, follow the same spacing rules with AND or OR in between, e.g., “B64C 15/12” AND “B64C 9/00”.
- Use only primary IPC: extracts only patents with the entered IPC if it is the primary (main) IPC.
Time range: enter the year range for the search.
Or Upload Patent List File: upload a .xlsx, .csv, .tsv, or .txt file of the patent numbers you'd like to analyze.
noteOr Upload Patent List File: The list must contain patent numbers corresponding to the status (Application or Granted) and issuing authority (e.g. USPTO-A, EPO-G, etc.) of the selected database. [Download a sample] (US-R)
If the uploaded list contains fewer patents than the analysis maximum, the results will contain the patents on the list and others pulled from the database according to text similarities. To create an analysis with only the patents on the uploaded list, enter the total number of patents on the list in the Sampling Threshold field (Data Sets → Analyze → Sampling Threshold)
Delete and change package: to stop this process and return to the home page, click [X] next to the current package. All data entered for this search will be erased.
Create Data Set: click to create the data set.
Data Sets: view all of your data sets here. To analyze, select one or multiple data sets you want to include in an analysis.
Under Analyze, confirm the Data settings:
Analysis Name: enter the name you'd like to give your analysis. If left blank, an analysis number will automatically be assigned.
Data Set: selected data sets will be listed here. Total Documents gives the cumulative number of patents in all selected data sets.
Part of Document to Analyze: confirm the part of the patent to be used for the analysis.
Sampling Threshold: confirm the number of patents to include in the analysis.
noteIf the total number of patents in the selected data sets is higher than the maximum allowable on your account, a calculated sampling will be extracted for the analysis
Use Options to apply custom rules to the analysis calculation.
Name Normalization is the aggregation of IPC, company, or inventor names. To apply a new rule, create and upload a file under the More dropdown → Name Normalization. Sample File
Cluster Strength increases or decreases the cluster volume by adjusting the similarity threshold.
Strong → fewer clusters with more documents per cluster.
Weak → more clusters with fewer documents per cluster.
Cluster Count allows you to specify the exact number of clusters created during the calculation process. To create an unclustered analysis, enter the Total Documents number of the data sets you want to analyze. See Data → Data Set → Total Documents.
Word Importance is the adjustment of the level of relevance of certain words during the similarity calculation and clustering process. Words can be emphasized, weakened, or excluded. To apply a new rule, create and upload a file under the More dropdown → Word Importance. Sample File
Word Grouping puts synonymous words together and runs them as one in the calculation process. To apply a new rule, create and upload a file under the More dropdown → Word Grouping. Sample File
Indexical Analyzer controls the parameters of the 2D visualization according to the number of documents in the data set and the scope of their contents. If a data set broadly covers a topic or field, e.g. renewable energy, set it to broad. If it is specific, e.g. solar power energy storage and transfer, set it to specific. For patent volume, low is less than 1,000. Average is 1,000-5,000. High is 5,000+.
Advanced Options: adjust calculation settings for Contour Lines, Gravity Distance Transition, and Noteworthy Areas.

- Density: shows the integration density of each cluster of the target company. X and Y axes are the integration density of the target compared to others in the data set. The blue line is a least-squares method regression line. The red dotted lines are 3-sigma lines. The plots above the blue line are the target's strengths, those below are its weaknesses. The further from the axes origin the more unique. (See SWOT above for more details)

Positive and negative numbers indicate if their center of gravity is moving away from (+) or approaching (-) the target. Also see synergy classifications below.
- Distance vs Radius of Area: shows the overlap and distances between the target's patent distribution range and center of gravity compared to others in the data set. X-axis shows the area of distribution. Y-axis shows the distance between the target's gravity and the others.
