USPTO Patent Grant Rate and Growing Backlog
Patent – Patently-O 2024-11-29
Summary:
by Dennis Crouch The USPTO utility patent grant rate data reveals an interesting narrative of policy shifts and administrative changes over the past fifteen years. The graph shows a clear upward trajectory from a notable low point around December 2009, when the grant rate bottomed out near 50%, to recent levels hovering around 75-80%. This dramatic shift beginning in 2010 coincided with Director David Kappos taking the helm at the USPTO, marking a decisive break from the more restrictive patent policies of his predecessor Jon Dudas. Under Kappos’s leadership, the office embraced a more applicant-friendly approach, focusing on working with inventors to achieve allowable claims rather than pursuing multiple rounds of rejection.
More recent data points to subtle but noteworthy changes in USPTO practice. Since Director Kathi Vidal’s confirmation in April 2022, the grant rate has shown a modest decline from its peak levels of around 80-85% during 2020-2021. While the current grant rate remains substantially higher than the pre-Kappos era, this recent downward trend suggests a potential recalibration of examination practices under Vidal’s leadership.
The grant rate shown in the graph represents a monthly calculation derived by dividing the number of issued patents by the total number of resolved patent applications for each month, but with an important limitation: the analysis includes only published patent applications.
