Time Series Map

One of the most basic Patent Maps is to collect patent documents for a particular right-holder,

arrange them by year of filing of patent application, and plot the number of patents or patent

applicaitons. This is called a Time Series Map and is easily created by anyone.

 How to Read the Map

A Time Series Map is used to analyze the trends of applicants or inventors as well as the number

of patent applications filed and patents issued.
