How many patents have been issued since 1970?

There's a bit of an odd question for you, but the answer is easy enough by checking out the U.S. Patent Office's historical statistics. Turns out they issue about 100,000 or more patents a year these day, not quite so much in past years. Total from 1970-2009: 4,553,317 patents!
