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? Quantitative Analysis Qualitative Analysis Patent Map
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
