Special notes on statistics
  • Statistical data is not available for IP Offices that did not provide statistical information, or for IP Offices that had no PPH request during the period.
  • For the CNIPA (China), the DPMA(Germany), the USPTO (US), the figure for "National_PPH" includes the figure for "PCT_PPH."
  • For the CIPO (Canada), the average first action pendency and the average total pendency for "all_applications" are those for non-PPH applications.
  • The first action allowance rate at the DPMA (Germany) is low because the Office may issue actions for minor formal defects.
