Independent's Patent Share Dropping

Independent inventors’ share of patents issued to U.S. inventors has been declining. Starting with a 22.9 percent share in 1998, the percentage dropped to 21.8 percent in 1990, then to 21.0 percent in 2000, 19.2 percent in 2001, 17.1 percent in 2003, and then to 16.1 percent in 2004.

In other words, the drop over a six year period from 1998 to 2004 was 6.8 percentage points, from a 22.9 percent share down to a 16.1 percent share.

Data has not been located regarding the percentage of independent inventor application filings. Whether the decline in share of issued patents tracks the filing rate or the approval rate remains, therefore, indeterminable.
