Assessing the productivity of a law firm is a tricky business, and can be measured in multiple ways, including total number of applications filed, number of attorneys, and number of patents granted, among others. More than just measuring the total output of a firm, we were interested in measuring the productivity of patent prosecutors (attorneys and agents) inside a firm. Due to employee turnover, measuring this at the firm level is somewhat of a difficult task. However, in an attempt to minimize the influence of turnover, we limited our results to those firms among IP Today’s 2015 top patent firms that had at least 10 prosecutors and we restricted the date range to patents granted within the last 10 years.
Below is a ranking of firms that meet the above criteria based on an approximation of the average number of patents granted per prosecutor per year.
