March 2026: 1.26% (C+ grade)
Rhode Island inventionINDEX March 2026: 1.26% (C+ 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).

The March 2026 Rhode Island inventionINDEX score of 1.26 percent marks a period of modest recovery following a turbulent start to the year. While the current C+ rating represents an improvement over the February 2026 score of 0.59 percent, which stands as a multi-year low for the state, it remains a step down from the 1.43 percent B- rating recorded in January. This early-year volatility suggests that the state is currently in a transitional phase, struggling to reclaim the consistent innovation momentum that characterized the final quarter of 2025 when the index maintained a steady A rating or higher.
When viewed across the sixty-month historical horizon, the current performance is significantly lower than the state’s demonstrated potential. Rhode Island has frequently achieved the A+ tier, reaching historical peaks of 3.77 percent in both June 2021 and September 2023. More recently, the state enjoyed a robust period between July and October of 2025, consistently posting scores above 2.50 percent. The current C+ rating more closely reflects the inconsistent output levels observed in early 2022 rather than the high-growth phases that defined its most successful years, indicating a need for renewed focus on regional development and creative output.
The attainment of a higher grade, particularly in the A and A+ categories, creates a powerful catalyst for Rhode Island’s economic development. High inventionINDEX scores serve as a signal to global investors and venture capitalists that the state possesses a fertile environment for intellectual property creation and commercialization. These periods of excellence typically correlate with increased funding for local startups, the expansion of research and development facilities, and the creation of high-value jobs within the technology and manufacturing sectors. By maintaining a top-tier rating, the state reinforces its reputation as a competitive hub for innovation, attracting specialized talent and fostering long-term industrial resilience.
On the other hand, the implications of lower scores or the D-tier performance seen in early 2026 are concerning for the state’s economic outlook. A lower index score often reflects a stagnation in patent activity, a reduction in research initiatives, or systemic barriers to taking new ideas to market. These downturns can lead to a erosion of investor confidence and may prompt creative professionals to migrate to more active innovation ecosystems. If Rhode Island remains in the lower tiers for an extended duration, it faces the risk of falling behind regional competitors, making the task of revitalizing its innovative sectors increasingly difficult and costly.
Discussion:
In March, the Rhode Island inventionINDEX scored a positive sentiment which was lower than the previous year’s average and underperformed the downward trend for the year. This is similar to the prior 12 months, which experienced a slight 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.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
