After reading this post from Eric Sutton over on Patnotechnic (follow it, if you don’t already), I decided to graph PTAB institutions vs. Examiner Allowance rate1:
As you can see, higher institution rates follow higher allowance rates. Happy to send the data behind this graph to anyone who wants it.
You can check out any particular examiner’s allowance rate here
1The allowance rate is the Examiner’s current allowance rate calculated as described here (not the examiner’s allowance rate at the time the respective patent was allowed).
