Robust technology, semiconductor and bioagriculture industries drive Idaho's patent activity.

The state is home to tech giant Micron Technology (MU) and the Idaho National Laboratory, which is a research and engineering facility owned by the Department of Energy.

"Lately we're seeing clusters of new tech startups that have branched out of the National Lab and the big tech companies here," said Clark Krause, executive director of the Boise Valley Economic Partnership.

The Boise region, which hosts a large Hewlett-Packard (HPQ) plant, is among the top 20 U.S. metro regions for most patents.
