Patent Mapping and Patent Families – Case Studies
Background
Information is required in order to…• allow for good patent prosecution• provide a basis for portfolio development • watch competitors’ patent portfolio• react to inquiries• help in M&A projects
What is Patent Mapping?Patent Mapping…• is a tool for assessing large sets of patent data• allows the creation of a visual representation of
information from and about patent documents in a way that is easy to understand
• can identify which technical fields particular applicants are active in, and how their filing patterns and IP portfolios change over time
• helps to find out which countries are particularly active in certain technical fields
Who Uses Patent Mapping?Patent Mapping can provide valuable information
for…• corporate decision-makers• investors (venture capitalists, promotional banks)• innovators (R&D)• influencers (patent offices, policy-makers)• management
How is a Patent Map created?Gathering of Information:• define the data to be included in the analysis • choose a database that covers the required
information • define your query • collect data• remove “noise” (irrelevant or insufficient
information)• fine-tune results, e.g., harmonize applicants' names
How is a Patent Map created?Quantitative Analysis
statistically analyzing patent information typically useful data comes from bibliographical
information (e.g., number of patent applications, assignees, inventors, or patent classification codes, etc
examples:- number-based analysis- time-based analysis- ranking analysis
How is a Patent Map created?Qualitative Analysis
analyzing the content of patent applications/ patents
analysis can be performed by inter-relating technology contents, patent classification codes, assignees, application dates (e.g., selecting a core patent)

How is a Patent Map created?Analyzing of Information:• carry out a statistical analysis of structured information
(bibliographic data, inventors, titles, …)• do text mining on unstructured information such as
abstracts• export data to a spreadsheet / database• define the purpose of analysis (technologies, application,
…) • add categories of information to documents • run a statistical analysis • check results
How is a Patent Map created?Visualizing Results:• visualize results of statistical analysis by creating a
patent map• there are many different kinds of patent maps for
various purposes and users• various graphs can be used to show the results of
statistical analysis
