Where retired USPTO systems moved (TESS, PAIR, PatFT/AppFT and more)
USPTO replaces its online systems one at a time, so searching an old name such as TESS, PAIR or PatFT/AppFT rarely tells you which official page to use now. This page lists the current replacement for every retired system in one table. Fees and whether an account is required are given on the sourced detail pages, each with the source URL and the date it was checked.
