The checklist has a some large caveats.  (1) The information will come from the USPTO register, and some attorneys are not good at updating their information. For example. Kenyon & Kenyon closed its doors in 2016, but 30+ registrations still record the business.  (2) A selection of folks use their home (or some other) address alternatively than business handle for the registration. (3) Retired people normally do not update their registration.
