In 2024, the forecast for total patents in environmental technologies in the US is 8.54, representing a slight decline compared to values in previous years. Compared to 2023, this marks a continuous downward trend in environmental patent registrations. The forecasted year-on-year decline is consistent from 2024 to 2028, showcasing a slow but noticeable shrinkage in patent activities in this sector, with a compound annual growth rate (CAGR) indicating a decrease in innovation momentum.

Future trends to watch for:

A shift towards clean energy innovations might stimulate patent growth.
Increasing government incentives and funding could alter the declining trend.
Emerging global sustainability mandates might also influence patent filings positively.
