How do I create a patent map? What are the steps involved?

Step 1: gather

- Define the data to include in the analysis
- Choose a database that covers the required information
- Define your query (dates, IPC, keywords, etc.)
- Collect data; remove noise, i.e. irrelevant or insufficient information
- Harmonise applicants' names

Step 2: analyse

Carry out a statistical analysis of structured information such as bibliographic data, inventors' names, titles of inventions, etc. Do text mining on unstructured information such as abstracts, descriptions and claims.

- Export the data (full data set) to a spreadsheet
- Define the purpose of analysis (e.g. technologies, application)
- Add categories of information to documents
- Run a statistical analysis
- Check results

Step 3: visualise

Visualise the results of your statistical analysis by creating your patent map. There are many different kinds of patent maps for various purposes and users. You can use various graphs to show the results of your statistical analysis, for example simple bar or line charts, area graphs or bubble charts. These are all forms of patent maps.
