February 2026: 1.34% (B grade)

South Carolina inventionINDEX February 2026: 1.34% (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).

South Carolina inventionINDEX Scores – Last 12 months

The February 2026 inventionINDEX for South Carolina reached 1.34 percent, resulting in a B rating. This represents a modest improvement from the 1.23 percent recorded in January 2026, which held a B-minus rating. Over the 60-month period analyzed, the index has experienced considerable fluctuations, moving between a low of 1.06 percent in mid-2022 and a peak of 1.93 percent in late 2025. The current score places the state in a stable, mid-range position, reflecting a consistent but non-extraordinary level of inventive activity relative to its five-year history.

When the inventionINDEX achieves higher grades, such as the A-plus ratings observed in September 2025 and March 2021, the implications for the local economy are substantial. A higher score typically indicates a robust ecosystem where intellectual property is being generated at an accelerated pace. These peaks suggest that South Carolina is successfully fostering an environment conducive to research and development, which can attract venture capital and high-tech industries to the region. A strong grade serves as a signal to global markets that the state is a hub for progress, potentially leading to increased job opportunities and a higher standard of living through technological advancement.

Conversely, a decline in the score toward the C range, as seen in October 2025 and July 2022, presents certain risks to the regional economy. A lower rating often reflects a slowdown in patent filings or a decrease in the commercialization of new ideas, which can lead to industrial stagnation. If these downward trends persist, South Carolina may face challenges in maintaining its competitive edge against neighboring states that are investing more heavily in their innovation infrastructure. Negative implications include the potential for a brain drain, where top-tier talent leaves the state in search of more dynamic environments, and a reduction in the long-term growth potential of the manufacturing and technology sectors.

Looking at the historical data as a whole, the volatility of the inventionINDEX underscores the need for continuous support of the state’s innovation pipeline. While the 1.34 percent score for February 2026 is a positive step up from the start of the year, it remains well below the record high of 1.93 percent. Sustaining a trajectory toward the A-range requires a balanced approach to education, infrastructure, and corporate incentives. By monitoring these shifts closely, stakeholders can better understand the factors driving the state’s creative output and work to ensure that South Carolina remains a leader in the national landscape of invention and enterprise.

Discussion:

In February, the South Carolina inventionINDEX scored a positive sentiment which was lower than the previous year’s average but outperformed the downward trend for the year. This is in contrast 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.
