The final patent numbers for 2006 are in.

A record 944 patents were granted to Utah inventors in 2006, a 26 percent increase over the 749 patents granted to Utahns in 2005. The increase is a more modest 3 percent when compared with 2001, the previous record year, in which Utah inventors netted 917 patents.

The total number of patents granted by the U.S. Patent Office also rose sharply to 196,441 in 2006, up 24.4 percent from the 157,882 patents it granted in 2005.

As innovation increased in the 1980s and 1990s, the number of patents granted annually to Utahns rose steadily each year, until 2002. The annual patent totals dropped in 2002 and 2003. The receding economic times of 2001 had been blamed as a primary reason for the slide.

Economic recovery fueled an increase to 900 patents granted to Utahns in 2004. A record drop followed in 2005, to 749 patents, which was seen as the result of a huge nationwide increase in innovation and consequential backlogs in an understaffed U.S. Patent Office. The Patent Office has taken steps to better manage the steady increases in innovation.

Patent grants to Utahns had climbed steadily each year since the late 1970s and early 1980s, when Utahns typically were granted about 200 patents annually. Since 1988, a year in which Utah inventors garnered 292 patents, Utahns' patent numbers increased annually until 2002, a span that involved sometimes dramatic annual increases reaching as high as 35 percent in some years.
