USPTO will be updating reCAPTCHA V2 to reCAPTCHA V3, which will no longer
require users to pass a challenge test to access Public PAIR. Instead,
system monitoring will determine human interaction versus data mining.
If the reCAPTCHA V3 system mistakenly identifies human interaction as
data mining, users will be able to select the “Refresh” link to
reestablish Public PAIR access.
The
update requires Public PAIR to be unavailable from 12:01-4 a.m. ET,
Friday, January 17. Users will still be able to access Private PAIR and
EFS-Web during this maintenance period.
Please contact the Electronic Business Center (EBC) at 866-217-9197 or ebc@uspto.gov from 6:00 a.m. to midnight ET, Monday through Friday, for assistance.
