The final patent numbers for 2007 are in.

A total of 903 patents were granted to Utah inventors in 2007, a decrease of 4.3 percent from the 944 patents granted to Utahns in 2006. However, the 2007 patent-grant total is still the third-highest total to Utahns in history, trailing only the 2006 total and the 2001 total of 917 patents.

The total number of patents granted by the U.S. Patent Office also dropped a bit in 2007 as well. The office granted 182,951 patents in 2007, down 6.9 percent from the 196,441 patents it granted in 2006. However, the 2007 total exceeds substantially the 2005 total of 157,882.

Patent grants to Utahns had climbed steadily each year in the late 1970s and early 1980s, when Utahns were typically granted about 200 patents annually. From 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.

Seventeen patents were awarded to Utah inventors on Jan. 1 of this year.
