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


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


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)

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


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

number of records filed during 2000 to 2005: >3000

number of records considered for mapping: 127

basis for selection of patent records: Assignees with more than15 patent records
