April 2026: 1.08% (C+ grade)
Maryland inventionINDEX April 2026: 1.08% (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 April 2026 Maryland inventionINDEX score of 1.08 percent, yielding a C-plus rating, represents a notable cooling period for the state’s innovation sector. This figure is particularly striking when compared to the performance of previous Aprils within the 60-month dataset. For example, the state recorded an A-plus rating with 1.42 percent in April 2025 and 1.36 percent in April 2024. Even in 2021 and 2022, April scores remained firmly in the A or high B ranges. The current decline from March 2026’s 1.28 percent indicates a loss of short-term momentum, placing the state at its lowest April performance level in five years.
Looking at the broader historical context, Maryland has consistently demonstrated a high ceiling for creative and technical output. Over the last five years, the index has frequently reached the A-plus range, peaking at 1.59 percent in October 2023 and 1.48 percent in June 2021. Aside from a significant statistical outlier in May 2023, where the score plummeted to 0.58 percent, the state has traditionally maintained a presence in the B-plus to A range. The current C-plus rating is a rare departure from this high-performance baseline, suggesting that the local innovation ecosystem is currently operating below its established historical capacity.
The positive outcomes of achieving a higher grade on the inventionINDEX are vital for Maryland’s long-term economic health. When the state operates in the A range, it typically reflects a robust environment for patent filings, increased research and development spending, and a high level of synergy between academic institutions and private industry. These higher scores serve as a powerful signal to venture capitalists and federal agencies that the region is a safe and productive bet for investment. This influx of capital and interest often leads to the creation of high-paying jobs in biotechnology, aerospace, and cybersecurity, further cementing the state’s reputation as a national leader in technological advancement.
On the other hand, the negative implications of a lower score or a sustained slide into the C range cannot be ignored. A lower inventionINDEX score may indicate a bottleneck in the commercialization of new ideas or a reduction in the resources available to independent inventors and startups. If the index continues to hover near the 1.00 percent mark, there is a risk of talent migration as top-tier researchers seek more active innovation hubs. Furthermore, a lower rating can lead to a more risk-averse investment climate, making it difficult for local entrepreneurs to secure the funding necessary to move from the prototype phase to market entry. Analyzing these trends is essential for stakeholders looking to implement strategies that will return the state to its peak performance levels.
Discussion:
In April, the Maryland 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.
