The Invention Index measures a country’s or state’s innovation output by comparing GDP growth with patent production growth. 

Maine Invention Index August 2023: 1.05% (C grade)

Maine Invention Index over the last year:

ME Invention INDEX (22)

Anything over C grade is positive sentiment; anything under C is negative outlook/sentiment. Using that sentiment, it is possible to observe trends over time, and also compare states/countries. In doing so we can predict which states have the best chance to recover economically from the pandemic (or any other economic incident that may occur).


In August, the Maine Invention Index scored a positive sentiment which was higher than the previous year’s average and outperformed the upward trend for the year. This is similar to the prior 12 months, which experienced a slight upward trend. There has been no sudden drop in patent numbers, despite the evolving situation with Covid-19. However, it is possible that these approvals are happening on patents applied for prior to the Covid-19 outbreak. If this is the case, we may see a decrease in approvals – and a reduced Invention Index – in the coming months/years as the state feels the full economic impact of companies closing and/or being forced to minimize their staffing and therefore minimize their R&D work hours.
