Ohio inventionINDEX September 2026: 4.58% (A+ 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 Ohio inventionINDEX Scores

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

The Ohio inventionINDEX reached a 60-month peak in September 2026 with a score of 4.58% and an A+ rating, reflecting a substantial upward surge from August 2026 at 2.97% (A-) and July 2026 at 1.55% (C+). This landmark performance eclipses the previous historic high of 4.56% recorded in January 2024, while standing significantly above the five-year monthly average of 2.32% and median of 2.05%. Comparing this remarkable outcome against past cyclical downturns, such as the record low of 0.64% in December 2022 or the 0.84% recorded in October 2025, illustrates a major expansion in regional inventive output and commercialization velocity over the recent multi-quarter trajectory.

Achieving high index values and upper-tier ratings like A+ or A yields profound benefits for the state economy and innovation ecosystem. Exceptional scores signal a fertile environment for intellectual property creation, encouraging increased venture capital inflow, corporate research investment, and talent retention. Moreover, stronger scores enhance institutional credibility, making it easier for university tech-transfer offices and technology incubators to attract grant funding, secure federal commercialization awards, and forge cross-industry development partnerships that turn proprietary discoveries into scalable products.

Conversely, sustained periods of lower scores and diminished ratings, such as C- or D levels, expose vulnerabilities within the regional technology pipeline. When the score contracts toward historical troughs, it often indicates capital constraints, regulatory bottlenecks, or reduced patent filings across key industrial sectors. A subdued rating can dampen investor enthusiasm, slow down start-up formation, and delay the transition of early-stage research into commercial markets, ultimately placing regional enterprises at a competitive disadvantage relative to faster-moving national hubs.

Overall, the trend lines demonstrate that while the Ohio inventionINDEX experiences short-term fluctuations, the underlying momentum remains robust when anchored by strong quarterly peaks. Navigating the natural cyclicality between low-scoring adjustment phases and high-scoring breakthroughs requires ongoing public-private collaboration, targeted seed-stage financing, and persistent support for commercialization infrastructure. Maintaining high performance over extended periods will be key to converting short-term surges into durable, multi-year economic growth across Ohio.

Discussion:

In September, the Ohio inventionINDEX 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 an upward 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.
