USPTO bulk data: the Trademark Case Files Dataset (TRCFECO2; the latest release, March 2024, runs through 2023) for marks, owners, classes and goods and services; the Trademark Assignment Dataset (TRASECO) for assignments. Marks filed in the last 20 years, plus older marks still registered. Status here is read from the dataset’s dates and status code; TSDR has the current status. Links to other records are by name (and state): EXACT means the identical full name and state; FUZZY means a looser name match, with the confidence shown.
