Which ISAs do US filers choose?

WIPO provides a very nice statistics lookup tool on its web site.  I used that tool to make this pie chart showing the International Searching Authorities that were chosen in 2018 by filers in RO/US.

As you can see, ISA/EP, ISA/KR, ISA/RU and ISA/US accounted for virtually all choices made by US filers.  Ranked by percentage, they were:

  • 39.48% EP
  • 37.79% US
  • 16.23% KR
  •   5.24% RU

These four ISAs together accounted for more than 98 percent of choices.
