The chart above shows that the trend is continuing — more inventors per patent application. The rising series are applications with 3 or more listed inventors and the declining series are those applications with only 1 listed inventor. The percentage of applications with 2 listed inventors is remaining fairly constant over the past 15 years. I’ll do a follow-up showing that more-inventors correlates with higher allowance rate. The series stops in Spring 2018 because of the 18-month publication delay of new applications.
