bag8ger, Why don't you?
And then tell us how the process breaks down.
How many patents are approved with 'no' rejections?
How many are approved after a 'non-final' rejection?
How many after a 'final' rejection?
How many after two 'non-final' and one 'final'?
etc., etc., etc,....
Don't forget to assess how many 'claims' are removed from the application on average for each step.
Then after you have worked out the respective percentages of each, tell us how you derive the 'routine' aspect of your characterization. LOL
