Answers: what is the status of each of these applications — the `status` block, patent/publication numbers and applicant for up to 1,000 application numbers, in request order; a number we do not hold comes back in `not_found`, one that cannot be an application number in `invalid`, as you wrote it. Costs 1 request per 100 rows returned. Use /v1/applications/{n} for the full object.
