An excellent publication by Michael Kaminski, a partner at Foley & Lardner, describes 27 possible metrics and measurements that a company can choose from to describe its patent activities.
Kaminski breaks the metrics into eight groups, which he describes as “generally in order from most common or simple to increasingly esoteric” (at 10). These are the groups, with the number of metrics in it stated in the parenthesis: a charter (1), a “standard” set (4), a “product-centric” set (9), a “money saved” set (2), a “licensing” set (3), a metric to quantify risk avoidance (1), a “patent citation” set (3), and an “accounting information” set (4).
