West Virginia inventionINDEX September 2026: 1.24% (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 West Virginia inventionINDEX Scores

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

The West Virginia inventionINDEX recorded a score of 1.24% with a B- rating in September 2026, marking a notable rebound from the 1.03% C grade registered in August 2026. Over the evaluated 60-month historical period, this 1.24% mark aligns closely with the overall sample average of roughly 1.20%. It demonstrates a steady middle-tier trajectory that matches previous stabilizing months, such as April and July of 2026, while positioning the state comfortably above its mid-grade historical baseline.

When examined against multi-year highs and lows, the September 2026 performance shows significant resilience compared to softer periods in the dataset. For instance, the current 1.24% score represents a twofold increase over the 0.62% F grade logged in September 2025 and stands well above the historical lows of 0.41% seen in May 2025 and April 2022. While current performance remains below past ceiling marks like the 2.91% peak in July 2022 or the 2.28% high in October 2024, the broader trend suggests that the region has successfully navigated away from lower-tier fluctuations toward sustained stability.

Achieving higher inventionINDEX scores and superior ratings yields substantive structural advantages for the regional innovation ecosystem. Stronger ratings, particularly in the A-range such as the 1.87% scores achieved in early 2026, signal robust inventive vitality, enhanced intellectual property activity, and heightened investor confidence. Elevated marks attract capital, encourage research collaboration across academic and industrial sectors, and foster an environment where local startups can scale efficiently.

Conversely, sustained drops into lower rating tiers present notable operational and economic risks for the region. Lower scores, like the D+ and F grades observed during mid-2025, reflect diminished inventive output, stalled commercialization pathways, and potential capital flight to more competitive markets. Persistent underperformance in the index can stifle talent retention and suppress long-term economic growth, underscoring the vital necessity of maintaining proactive policy support, innovation infrastructure, and research investment across West Virginia.

Discussion:

In September, the West Virginia inventionINDEX scored a positive sentiment which was higher than the previous year’s average and outperformed the downward trend for the year. This is similar 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.
