Frequently Asked Questions
DATAMP FAQ'sQ: What is DATAMP?
A: DATAMP is an acronym for Directory of American Tool and Machinery Patents. Over the years DATAMP has expanded to include all of the early (pre-July 1836) U.S. patents that weren't originally numbered and were lost in a fire in December 1836. Of the approximately 10,000 of these patents, about 2,000 were restored from the original patent holders copies of their patents. The other 8,000 or so, we have only the name of the patent and that of the patentee, although we have found information about some of them from other sources. Of the 63,363 patents currently in DATAMP, 18,425 have links to Vintagemachinery.org containing information about the patent's manufacturer.
