Rhode Island inventionINDEX September 2026: 2.60% (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 Rhode Island inventionINDEX Scores

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

The Rhode Island inventionINDEX has demonstrated a remarkable rebound in recent months, positioning the state’s innovation climate near historic highs. Following a brief period of suppression in early 2026—culminating in a five-year low of 0.59 percent and a D rating in February 2026—the index orchestrated a rapid recovery beginning in April 2026. By August 2026, the score surged to 3.60 percent with an A+ rating, marking the second-highest monthly performance across the entire 60-month dataset. September 2026 sustained this momentum with a solid 2.60 percent score and an A+ grade, reflecting a robust six-month streak of top-tier performance that underscores renewed vitality in regional inventive activity.

When evaluated against the broader 60-month historical trajectory from September 2021 through September 2026, the current figures reflect an impressive return to peak operational strength. Over this five-year span, the index has experienced episodic volatility, ranging from peak performances such as 3.77 percent in September 2023 to cyclical troughs seen in mid-2022 and early 2026. Comparing the late 2026 performance with previous annual cycles reveals that the current stretch from April to September 2026 represents one of the most consistently high-performing six-month spans recorded, rivaling the strong multi-month rallies observed in late 2023 and mid-2025.

Achieving higher scores and top-tier grades like A and A+ carries significant positive outcomes for the state’s economic ecosystem. Elevated ratings signal a flourishing innovation environment, attracting private venture capital, encouraging research and development investment, and fostering collaboration between academia and local industry. High inventionINDEX scores often correlate with accelerated patent filings, high-value tech sector job growth, and enhanced commercialization of novel technologies, which together elevate Rhode Island’s competitive stature within the regional and national economy.

Conversely, lower scores and diminished grades, such as the C and D ratings observed during down periods in early 2022 and early 2026, indicate potential systemic headwinds. Drops in the index reflect reduced intellectual property output, tighter capital availability, or broader economic contraction affecting inventive enterprises. Protracted periods of lower scores risk weakening investor confidence, delaying product development cycles, and driving creative talent toward more dynamic regional markets, emphasizing the necessity of sustained support for the state’s innovation infrastructure.

Discussion:

In September, the Rhode Island inventionINDEX scored a positive sentiment which was higher than the previous year’s average but underperformed 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.
