Between the 1980s and the 2000s, based on patents filed/1000 population, innovations has strongly increased in the western US, but we also see strong growth in the Intermountain region (ID, UT, CO), plus Texas, MN, MI and New England.

One big changes, besides the growth in computing and semiconductors, is that software patents were not allowed in the 1980s. That new category opened opportunities for many more patent filings.
