Michigan inventionINDEX September 2026: 1.71% (B- grade)

The inventionINDEX measures innovation output by comparing GDP growth with patent production growth.

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).

Historical Michigan inventionINDEX Scores

The Michigan inventionINDEX score for the past 12 months is shown in the table below.

The September 2026 Michigan inventionINDEX recorded a score of 1.71% with a B- rating, reflecting clear upward momentum compared to the preceding summer months. In August 2026, the score stood at 1.37% with a C+ rating, while July 2026 registered at 1.03% with a C rating. This consecutive monthly increase demonstrates an encouraging rebound after a relative slowdown in mid-2026, where scores dipped below 1.00% in April at 0.98%. Compared to the trailing twelve-month average of approximately 1.32%, the latest figure represents a solid gain of nearly 40 basis points. The recent trajectory indicates renewed vigor in early-stage innovation metrics, patent filings, and local entrepreneurial activity across the state.

When evaluated across the broader 60-month historical timeline, the September 2026 outcome sits comfortably above the five-year baseline average of 1.46%. While it remains below the historic peaks observed in September 2023 at 3.09% A+, August 2023 at 2.94% A+, and October 2024 at 2.97% A+, it signifies a resilient recovery from historical troughs. The index reached its lowest point in July 2023 with a score of -0.11% and an F rating, alongside occasional dips into the D range such as October 2023 at 0.21%. Positioned in the upper middle tier of historical performances, the current score confirms that the regional innovation engine is operating efficiently without exhibiting severe volatility.

Securing a higher score and an elevated rating yields substantial positive strategic outcomes for the regional innovation landscape. Stronger grades signal robust commercialization activity, active intellectual property development, and heightened venture capital enthusiasm. An elevated rating instills greater confidence among early-stage investors, encourages research institutions to scale technology transfer initiatives, and attracts top-tier technical talent to the ecosystem. Higher scores often correlate with accelerated business formation, stronger university spinoff rates, and greater long-term economic resilience as novel technologies transition from concept to market expansion.

Conversely, persistent lower scores and depressed ratings bring critical negative implications for long-term economic health. Ratings falling into the lower C, D, or F tiers reflect stifled invention disclosures, funding bottlenecks, and reduced capital deployment. A prolonged downward trend can lead to investor risk aversion, delayed commercialization pipelines, and potential capital flight to competing technology hubs. Furthermore, weaker index performance places additional pressure on economic developers and academic centers to re-evaluate supporting infrastructure, funding mechanisms, and policy incentives necessary to rekindle regional inventive activity.

Discussion:

In September, the Michigan inventionINDEX scored a positive sentiment which was higher than the previous year’s average and outperformed the upward trend for the year. This is in contrast to the prior 12 months, which experienced a downward trend.

As the economy continues to stabilize in the post-pandemic era, it remains uncertain whether any backlog of applications still exists or if the department has returned to normal processing timelines. The inventionINDEX could also be affected by lingering consequences from the pandemic, such as company closures, reduced workforces, and limited R&D capabilities, which may still be impacting current operations.
