Abstract

The USPTO receives more applications today than it ever has before. What happens to those applications? Patent prosecutors all have stories and personal experiences. Until quite recently, however, this sort of “anecdata” was all that was available, because the law prevented anyone from every finding out what happened to patent applications that did not ultimately issue as patents.

That changed in 2001, when the PTO began publishing data on pending applications, and when the PAIR system allowed the public to track the fate of those applications in real time. In this paper, we use those changes to report – for the first time ever – systematic data on the fate of applications in the PTO. We are able to confirm much received wisdom, but also to offer some surprising results.
